Tracking the Oil Movements

The oil he industry counts on a small group of little-known companies whose main job is to count the number of tankers leaving ports, at best using data gathered from satellites, at worst using simple binoculars. They then guess how much crude is being carried by measuring the depth of the vessels in the water.

Swiss-based Petro-Logistics S.A., one of those companies, calls its work “the art and science of tanker tracking,” with the aim being to discover what oil producers “are really doing as distinct to what they say they are doing,” according to a statement on its website. While the information produced by companies such as Petro-Logistics and U.K.-based Oil Movements serves as a main input for estimates by consultants, traders and official bodies, it’s not the only measurement stick in use.

The matter becomes even more complex for oil moved within pipelines. Russia, for instance, exports roughly 30 percent of its crude via pipeline, according to official data. That flow is most often measured by independent groups using infra-red photography, which provides only a rough approximation of output.

The Organization of Petroleum Exporting Countries traditionally has published a measure of production based on what the group calls “secondary sources,” in effect consultants who calculate flows from a variety of sources, including tanker tracking data. The cartel also publishes production figures based on what OPEC countries release publicly.

The IEA and the U.S. government also publish estimates, as do many news organizations, including Bloomberg. The most recent addition to this flood of information is the Joint Organisations Data Initiative (JODI), a project begun in 2002 that’s backed by some of the world’s richest countries.Although all of these sources rely on tanker-tracking data as a base of their data, each group also incorporates its own market intelligence and different methodologies to come up with their data

Space Conquest: Brazil

vls-1, Brazilian Space Agency's satellitel launch vehicle. image from wikipedia

The Brazilian government is ending a decade-long project to operate Ukraine’s Cyclone-4 rocket from Brazilian territory following a government review that found too many open questions about its cost and future market success, the deputy chief of the Brazilian Space Agency (AEB) said.  It remains unclear whether the decision will force Brazil to pay Ukraine any financial penalties for a unilateral cancellation of a bilateral agreement. Over the years, the work to build a launch facility for Ukraine’s Cyclone at Brazil’s Alcantara spaceport has suffered multiple stops and starts as one side or the other fell short on its financial obligations to the effort…

“There have been challenges on the budget issues, on the technological aspects, in the relationship between Brazil and Ukraine and in the actual market for export that would be available. So it is a combination of things.”  said Petronio Noronha de Souza, AEB’s director of space policy and strategic investments.  The Alcantara Cyclone Space project was to give Brazil and Ukraine access to the global commercial launch market for satellites in low and medium Earth orbit, with the possibility of launching very light telecommunications satellites into geostationary orbit.

Noronha de Souza said the idea of making a profit in the launch business is now viewed as an illusion. The project, he said, was unlikely ever to be able to support itself on commercial revenue alone.  “Do you really believe launchers make money in any part of the world? I don’t believe so. If the government doesn’t buy launches and fund the development of technology, it does not work,” he said.  “Everybody talks about SpaceX [of Hawthorne, California] like it’s magic, somehow different. It’s no different. Their connections with NASA have been important. If NASA had stopped the funding, where would they be? I really appreciate what they are doing, but I doubt whether launch bases can make money and survive on their own without government support.”…

While the Cyclone-4 project is about to end, Brazil has maintained as a strategic goal the development of a space-launch vehicle from the Brazilian military-owned Alcantara facility. As such it is continuing work with the German Aerospace Center, DLR, on a small solid-fueled vehicle, called VLM-1 for Microsatellite Launch Vehicle, that began as a launcher for suborbital missions and has evolved to a small-satellite-launch capability….

AEB is a purely civilian agency funded through the Science and Technology Ministry. Until a few years ago, the Brazilian military had not been a player in the nation’s space policy. That is starting to change with the Brazilian Defense Ministry’s establishment of space-related operational requirements.  Among those requirements is a radar Earth observation satellite, which AEB has penciled into its program for around 2020. Aside from allowing the use of its Alcantara site, the Brazilian military is not yet financing any AEB work, but the military is expected to pay for launches of its satellites once the development is completed

AEB is finishing design of a small multimission satellite platform whose first launch will be of the Amazonia-1 Earth observation payload, with a medium-resolution imager of 10-meter-resolution, similar to the capacity of today’s larger China-Brazil CBERS-4 satellite, which is in orbit.

Brazil and Argentina’s CONAE space agency will be dividing responsibility for an ocean-observation satellite system, using the same multimission platform, called Sabia-Mar. The first Sabia-Mar is scheduled for launch in 2017, with a second in 2018, according to AEB planning.

Excerpts from Peter B. de Selding Brazil Pulling Out of Ukrainian Launcher Project,  Space News, Apr. 16, 2015

Russia has rushed to take advantage of the cancellation of space agreement between Brazil and Ukraine. [Russia] wants bot build  joint projects and space programs on the long term with BRICS Group member countries, particularly Brazil.  Brazil attempts to build its own cosmodrome, and unfortunately for the loss of Ukraine and its technology, the Brazilian-Ukrainian Project for the use of the Cyclone rocket in coastal launchings is practically minimalized…Russia proposed its variant of work, consisting in principle on the installation, already existent, of several satellite navigation stations Glonass and tbe idea of helping Brasilia in some way to the construction of the cosmodrome.

Connectivity to the Masses: Satellites for Africa

o3b satellites africa

Africa’s demand for bandwidth is doubling every year, outpacing the laying of terrestrial telecom fibre links and encouraging commercial satellite operators to launch more units into orbit.   The arrival of submarine cables on Africa’s eastern shore just five years ago (see e.g. Eastern Africa Submarine Cable System (EASSy)) was largely expected to herald the end of satellite connections, which had been the region’s only link to the outside world for decades.  But the opposite is happening with Africa’s political geography – notably its many landlocked countries, such as Zambia, South Sudan and Rwanda – bringing undersea cable plans back to earth.

“If you are to provide connectivity to the masses, fibre is not the way to do it. Do you think that it would make economical sense to take fibre to every village in Kenya?” said Ibrahima Guimba-Saidou, a senior executive for Africa at Luxembourg-based satellite operator SES SA “Satellite is still around and will continue to be around because it’s the best medium to extend connectivity to the masses.”  Hundreds of millions of people on the continent still have no access to the Internet, he said….

SES, one of the world’s largest commercial satellite operators, expects to launch its Astra2G satellite in 2014 after sending three others dedicated to Africa into orbit in the last year. Nine of its 56 satellites orbiting the earth are allocated for Africa.  Europe’s biggest satellite operator Eutelsat plans to fire off its tri-band EUTELSAT 3B this month after launching another to extend sub-Saharan Africa coverage in 2013.

The demand for Internet and data services in Africa has been driven by affordable mobile broadband connections. Mobile broadband users could grow by nearly eight times to 806 million by the end of 2018, according to Informa estimates.  New services such as digital television, onboard Internet connection for passenger aircraft, and delivering education and health services electronically will also drive demand.

The private sector has several initiatives to extend the capacity from submarine cables inland using terrestrial cables, but until that bottleneck is addressed, satellite operators are innovating to plug that black hole. One operator, O3B, or Other 3 Billion, has launched four of the next-generation medium earth orbit (MEO) satellites and plans two other launches in 2014 to make an orbital constellation of 12.  At a height of 8,000 kms (5,000 miles), the MEO units allow for faster speeds than traditional stationary satellites at 36,000 kms.  O3B’s tests have delivered capacity five times better than what traditional satellites can manage, making its technology suitable for both voice and interactive applications, said Omar Trujillo, vice president for Africa and Latin America….”A lot of applications for mining, oil and gas, will continue to be done by satellite,” he said. “The main market may not be international links for Nairobi or Johannesburg but will be communication for some of these remote areas that have had very low demand before, but now have fast-growing demand.

Space-the Wild West and the Five Eyes

Space is a current and future battleground without terrain, where invisible enemies conceivably could mount undetectable attacks to devastating effect if the right deterrent and defensive plans aren’t pursued now, the assistant defense secretary for global strategic affairs told a think tank audience on Sept. 17, 2013  Madelyn R. Creedon spoke to a Stimson Center gathering whose audience included analysts focused on the question of deterrence in space. The center released a publication this week titled “Anti-satellite Weapons, Deterrence and Sino-American Space Relations,” presenting a number of essays examining various perspectives on space deterrence.

Creedon noted that in Defense Department parlance, deterrence is “the prevention of action by the existence of a credible threat of unacceptable counteraction and/or the belief that the cost of action outweighs the perceived benefits.” In other words, she said, if deterrence is effective, an adversary has or believes he has more to lose than to gain by attacking.  Deterrence remains a core defense strategy for the United States, she added, and the nation’s nuclear deterrent is “still alive and well.”  Creedon acknowledged that one classic approach to considering space deterrence — that is, preventing potential enemies from attacking U.S. or partner satellites and other military or economic assets in space — is to try to apply lessons learned during the Cold War. Then, the United States and the Soviet Union kept an uneasy diplomatic truce and piled up enough nuclear weapons to guarantee mutually assured destruction.

But one flaw to comparing the two deterrent challenges, she said, is that an attack that disables a satellite, unlike one from a nuclear warhead that flattens a major city, doesn’t threaten a nation’s existence. Another is that the two superpowers spent decades constructing an elaborate, mirrored, deterrent Cold War architecture and protocols, while space is still, comparatively, “the Wild West.” A third is that an attack in space or cyberspace may rely on digital rather than conventional weapons, and so could occur without warning or even detection.

“If there is an attack against a space asset, it isn’t visible,” she said. “You can’t watch it on CNN, and unless you’re directly affected by the capability that the space assets provide, you’re probably completely oblivious that the attack happened.”

She said DOD is developing and implementing what safeguards it can implement in space using four mutually supportive elements to deter others from taking action against U.S. assets:

— Working to internationalize norms and establish a code of conduct to enhance stability;

— Building coalitions to enhance security;

— Adding resilience to U.S. space architectures; and

— Preparing for an attack on U.S. and allied space assets using defenses “not necessarily in space.”

“We believe this four-element approach … will bolster deterrence,” Creedon said.

The department is working with the State Department and international partners to define elements of good behavior in space, she said. “States must remain committed to enhance the welfare of humankind by cooperating with others to maintain the long-term sustainability, safety, security and stability of the outer-space environment,” she added.  Creedon said work is underway to build deterrent coalitions and increase space awareness. She said the “Five Eyes” nations, which include the United States, United Kingdom, Canada, Australia and New Zealand, are extending their intelligence cooperation to expand their collective space situational awareness

The United States is meanwhile working to lower the benefit to potential attackers by employing more satellites, participating in satellite constellations with other countries and purchasing payload space on commercial satellites when feasible.  Creedon said the U.S. approach to space deterrence is similar to its strategy in any domain: take “prudent preparations to survive, and to operate through, and, hopefully, prevail in any conflict.”

Space Weapons and Space Law

moon

“Policy, law and understanding of the threat to space is lagging behind the reality of what is out there,” warned Mark Roberts, a former Ministry of Defence official who was in charge of government space policy and the UK’s “offensive cyber portfolio”.….

The disabling of satellites would have a disastrous impact on society, knocking out GPS navigation systems and time signals. Banks, telecommunications, power and many infrastructures could fail, Roberts told the conference….Agreements such as the 1967 Outer Space treaty and the 1979 Moon treaty are supposed to control the arms race in space. Some states have signed but not ratified them, said Maria Pozza, research fellow at the Lauterpacht Centre for International Law at Cambridge University.  Existing treaties do not specify where air space ends and outer space begins – although 100km (62 miles) above the Earth is becoming the accepted limit.

The Navstar constellation of satellites was used to provide surveillance of Iraq during the Gulf war in 1991. Was that, asked Pozza, an aggressive use of space, a “force-multiplier”? Satellites may have also been used to photograph and locate al-Qaida bases, Osama bin Laden or even assess future strikes against Syria.

The Chinese government has recently moved to support a 2012 EU code of conduct for space development, which, Pozza said, was a softer law. The draft Prevention of the Placement of Weapons in Outer Space treaty has not yet been agreed. “Are we dismissing the possibility of a hard law or giving it a good chance?” Pozza asked.

The Chinese tested an anti-satellite weapon in 2007 that destroyed a defunct orbiting vehicle and showered debris across near Earth orbits. Other satellites have been jammed by strong radio signals. BBC transmissions to Iran were disrupted during this year’s elections through ground signals ostensibly sent from Syria.

In 2011, hackers gained control of the Terra Eos and Landsat satellites, Roberts said. The orbiting stations were not damaged. “The threat can now be from a laptop in someone’s bedroom,” he added.

Professor Richard Crowther, chief engineer at the UK Space Agency, said scientists were now exploring the possibility of robotic systems that grapple with and bring down disused satellites or laser weapons to clear away debris in orbit.  Both technologies, he pointed out, had a potential dual use as military weapons. 3D printing technologies would, furthermore, allow satellite operators to develop new hardware remotely in space.

The UK is formulating its space security policy, group captain Martin Johnson, deputy head of space policy at the MoD, said. Fylingdales, the Yorkshire monitoring station, has been cooperating for 50 years with the USA to enhance “space awareness” and early warning systems. The UK, Johnson said, was now working with the EU to develop a complementary space monitoring system.

Just Hit Seeme; the new military satellites of DARPA

Seeme Program Image from DARPA website

The Seeme Program from DARPA website:

DARPA’s SeeMe (Space Enabled Effects for Military Engagements) program aims to give mobile individual US warfighters access to on-demand, space-based tactical information in remote and beyond- line-of-sight conditions. If successful, SeeMe will provide small squads and individual teams the ability to receive timely imagery of their specific overseas location directly from a small satellite with the press of a button — something that’s currently not possible from military or commercial satellites.

The program seeks to develop a constellation of small “disposable” satellites, at a fraction of the cost of airborne systems, enabling deployed warfighters overseas to hit ‘see me’ on existing handheld devices to receive a satellite image of their precise location within 90 minutes. DARPA plans SeeMe to be an adjunct to unmanned aerial vehicle (UAV) technology, which provides local and regional very-high resolution coverage but cannot cover extended areas without frequent refueling. SeeMe aims to support warfighters in multiple deployed overseas locations simultaneously with no logistics or maintenance costs beyond the warfighters’ handheld devices.

The SeeMe constellation may consist of some two-dozen satellites, each lasting 60-90 days in a very low-earth orbit before de-orbiting and completely burning up, leaving no space debris and causing no re-entry hazard. The program may leverage DARPA’s Airborne Launch Assist Space Access (ALASA) program, which is developing an aircraft-based satellite launch platform for payloads on the order of 100 lbs. ALASA seeks to provide low-cost, rapid launch of small satellites into any required orbit, a capability not possible today from fixed ground launch sites.

From the DARPA Website

Raytheon Company was awarded a $1.5 million Defense Advanced Research Projects Agency (DARPA) contract for phase one of the agency’s Space Enabled Effects for Military Engagements (SeeMe) program. During the next nine months, the company will complete the design for small satellites to enhance warfighter situational awareness in the battlespace.  Raython News Release, Dec. 13, 2012

Battlespace: the Space-Based Infrared System and Missile Defense

The Space-Based Infrared System (SBIRS) is a consolidated system intended to meet the United States’ infrared space surveillance needs through the first two to three decades of the 21st century. The SBIRS program is designed to provide key capabilities the areas of missile warning  (MW), missile defense (MD) and battlespace characterization.

SBIRS is an integrated “system of systems” that will include satellites in geosynchronous orbit (GEO), sensors hosted on satellites in highly elliptical orbit (HEO), and ground-based data processing and control. SBIRS ground software integrates infrared sensor programs of the U.S. Air Force (USAF) with new IR sensors. SBIRS continues to struggle with cost overruns…. By September 2007, the expected project cost had increased to $10.4 billion

The original contract consisted of 2 HEO satellite sensors and 2-3 GEO sensors (and satellites) with an option to buy a total of 5 GEOs.

Exceprts from Wikipedia, SBIRS

Lockheed Martin’s SBIRS contracts include four highly elliptical orbiting (HEO) payloads, four GEO satellites, and ground assets to receive, process, and disseminate the infrared mission data. Lockheed Martin expects to receive funding to begin long lead parts procurement for the fifth and sixth GEO satellite by the end of the year (2012).

Lockheed Martin has received the GEO-4 (May 2012).   The GEO-4 structure, identical to the previous three SBIRS GEO spacecraft, is made from lightweight, high-strength composite materials designed to withstand the accelerations and vibrations generated during launch and support the spacecraft throughout on-orbit operations.  According to Lockheed Martin “Delivery of the SBIRS GEO-4 core structure is a major milestone indicating the program is continuing to meet its commitments….Based on lessons learned from the first two SBIRS geosynchronous satellites, production of GEO-3 and GEO-4 is proceeding very well. In addition, we have a number of affordability initiatives in place jointly with the Air Force to continually reduce the cost of each follow-on SBIRS satellite.”
