  DARPA awards nine new contracts to foster drone swarm technology

  Nathan Strout The Defense Advanced Research Projects Agency has issued nine new contracts to companies developing drone swarm technologies, the agency announced April 13. Through the agency's Offensive Swarm-Enabled Tactics program, or OFFSET, it hopes to foster technology developments that will enable 250 small unmanned air or ground robots to work together in support of the war fighter. The program works in five main areas: swarm tactics, swarm autonomy, human-swarm teaming, virtual environment and physical test bed. The agency has hosted multiple swarm sprints to encourage rapid innovation in one or more of those areas. The nine awards mark the fifth such swarm sprint, with this one focused on swarm tactics and physical test beds in an urban environment. “The urban environment presents compelling challenges such as tall buildings, tight spaces, and limited sight lines,” Timothy Chung, the OFFSET program manager in DARPA's Tactical Technology Office, said in an agency news release. “Enhancing the Swarm Physical Testbeds that tackle those unique challenges is a desired goal of the OFFSET program.” Four of the participants will be tackling the swarm tactics portion of the sprint, where they will be asked to solve problems such as “disrupting the opposition's decision making, obfuscating swarm intent, updating maps of a dynamic environment, and maintaining the swarm's communications indoors.” The remaining five performers will work on the physical test bed thrust area, which includes reducing deployment times, utilizing new navigation sensors, incorporating fixed-wing aircraft into the swarm and enhancing mobility for robotic, wheeled vehicles in urban settings. Participants will incorporate their technologies into the OFFSET swarm systems architecture to demonstrate their respective solutions, with field tests taking place in December 2020. The recipients are as follows: Thrust area: Physical test bed Michigan Technological University/Michigan Tech Research Institute Johns Hopkins University Applied Physics Laboratory HDT Expeditionary Systems, Inc.

  US eases military UAS export rules

  By Harry Lye The US has eased rules governing the export of military unmanned aerial systems (UAS) making it easier for it to sell UAS internationally. Under the new rules, announced by US State Department Assistant Secretary for Political-Military Affairs René Clarke Cooper, UAS that fly under 800kph (497mph) will no longer be subject to “presumption of denial” that made approving their sale more difficult. The change affects the US's implementation of the Missile Technology Control Regime (MTCR). Under the new rules, possible UAS sales will be vetted using rules already in place for other exports. Commenting on the change during a telebriefing, Cooper said: “All proposed transfers affected by this change will continue to be subject to the same rigorous review criteria that we have outlined in our UAS Export Policy, our Conventional Arms Transfer Policy, and of course, the Arms Export Control Act, as well as the specific non-proliferation criteria that has been identified in the MTCR Guidelines. “The United States is going to continue conducting our robust review procedures for exporting UAS technology to support global non-proliferation objectives, and we encourage members of the MTCR, as well as non-members such as China, to do the same.” The new rule change applies to UAS but will not affect systems such as cruise missiles, hypersonic aerial vehicles and ‘advanced unmanned aerial combat vehicles'. Cooper added that the subset of UAS covered by the new regulations ‘poses no risk for weapons of mass destruction delivery'. Commenting on the move in a statement the White House said: “While the Missile Technology Control Regime (MTCR) is critical in slowing proliferation and promoting peace and security, it is in dire need of modernization as it applies to UAS. In a sector of rapidly-evolving technology, the MTCR's standards are more than three decades old. “Not only do these outdated standards give an unfair advantage to countries outside of the MTCR and hurt United States industry, they also hinder our deterrence capability abroad by handicapping our partners and allies with subpar technology. More than two years of discussion with MTCR partners were unable to produce consensus on this overdue reform.” The White House added that the move would bolster US National Security “by improving the capabilities of our partners and increase our economic security by opening the expanding UAS market to United States industry,” adding that it saw the decision as an example for other MTCR members to follow. https://www.airforce-technology.com/news/us-eases-military-uas-export-rules/

  MDA to deliver mission-critical SAR information for maritime surveillance

  ichmond, BC - MDA, a Maxar Technologies company (formerly MacDonald, Dettwiler and Associates Ltd.), (NYSE: MAXR) (TSX: MAXR), today announced that it has signed a multi-million dollar contract with the South African National Space Agency (SANSA) for a one-year maritime surveillance program that includes the delivery of synthetic aperture radar (SAR) data products from the RADARSAT-2 satellite, using MDA's global network of ground receiving stations. The contract includes two additional option years. As part of the Presidential program Operation Phakisa, SANSA has been tasked to acquire SAR imagery with the aim of enhancing the monitoring and protection of South Africa's coastal regions and oceans. Initiatives under this program are considered crucial in accelerating the delivery of South Africa's development priorities. Operations Phakisa estimates that the approximate total contribution of coastal resources (marine fishing, port and harbour development, attractive lifestyles, recreation and tourism) is 35% of South Africa's GDP. The information provided by the SAR data contributes to ensuring improved governance and enables the securing of South African resources, such as the National Ocean and Coastal Information System. The South African Exclusive Economic Zone (EEZ) is roughly 1.5 million square km and forms part of the economic resources and trade routes of South Africa. The Council for Scientific and Industrial Research (CSIR), South Africa's central and premier scientific research and development organization will create the ship and oil detection products for SANSA to share with various government agencies. “RADARSAT-2 provides a unique method of cost-effectively and accurately monitoring very large areas and providing information in near real-time, demonstrating immediate value to users,” said Mike Greenley, group president of MDA. “MDA has decades of remote sensing expertise to help our customers anticipate and address their most complex mission-critical challenges with confidence.” Under this contract, using RADARSAT-2 information, MDA will provide systematic weekly broad-area surveillance over South Africa's EEZ and on-demand high-resolution image acquisitions. RADARSAT-2 Ocean Surveillance Mode is well suited for broad area maritime surveillance, and is unique as a single scene covers over 250,000 ㎢ and allows for the detection of ships and oil within the coastal and offshore regions regardless of light or weather condition. https://mdacorporation.com/news/pr/pr2018091001.html
