  DARPA wants a robotic satellite mechanic launched by 2022

  By: Nathan Strout   The Defense Advanced Research Projects Agency is on track to announce a new commercial partner for its robotic servicing payload by the end of the year, with plans to have a spacecraft in orbit in 2022. “I'm standing here with a smile on my face. The program is moving forward and things are looking good and we're very hopeful,” Joe Parrish, program manager for the Robotic Servicing of Geosynchronous Spacecraft program at DARPA, said at the 2019 Global Satellite Servicing Forum Oct. 1. “We're looking to launch RSGS in late 2022.” RSGS is intended to deliver a GEO spacecraft with a payload consisting of two large 2 meter arms and a number of tools that will allow it to perform maintenance and other work on satellites in GEO. The spacecraft will perform four main functions in space: inspection, orbital adjustments, anomaly resolution and installation of self-contained payloads. With a host of cameras onboard, RSGS will be able to inspect other satellites. This can help operators on the ground diagnose problems and inform in-orbit repairs. It can also use its arms to capture a satellite and move it, either to a new orbit or to dispose of it. DARPA envisions RSGS being able, again using its arms, to install new payloads on existing satellites, replacing legacy hardware and augmenting its mission for years to come. And, of course, RSGS will be available to traverse the GEO landscape to help satellites that fail to deploy correctly. “If somebody launches up into GEO while we're up there and a solar array fails to deploy or a reflector or antenna fails to deploy, we can come galloping to the rescue,” said Perrish. “The benefit is not to demonstrate robot arms waving around in space. The benefit is to increase the resilience of our infrastructure in space.” While DARPA is developing the payload with robotic arms, according to Parrish, DARPA needs a commercial partner to build the spacecraft that will house the payload and carry it around in orbit. “We're looking for the partner to provide the spacecraft bus — so using a heritage GEO bus that may have had some tailoring for RSGS requirements, integrating the payload and the spacecraft bus together, procuring and launching that integrated spacecraft to GEO, and then providing mission control center for operations for a long period of time,” explained Parrish. Parrish said that the full project would be turned over in due time to the commercial partner to operate RSGS for fun and profit. But DARPA has hit some stumbling blocks in securing that commercial partner. In 2017, Orbital ATK sued DARPA to stop it from developing what it saw as competition to its own satellite servicing space vehicle. While that effort failed, the company's efforts to develop its own satellite servicing program have continued. Orbital ATK was acquired by Northrop Grumman in 2018, and now the Northrop Grumman subsidiary SpaceLogistics is preparing to launch the first satellite life extension vehicle into space in the coming weeks. Then, in January, Maxar Technologies' Space Systems Loral pulled out of an agreement with DARPA to build the spacecraft to host the RSGS payload as the company moved out of the GEO construction market. DARPA has spent much of the last year working to find a new commercial partner. In May they hosted a Proposer's Day to discuss the program with potentially interested companies, and now Parrish says they expect to announce a partner toward the end of the year. “2019 has been quite a year,” said Parrish. “We are still in source selection for a new commercial partner.” Meanwhile, work on the payload itself is ongoing. The first of two flight robotic manipulator arms is in final assembly and will be shipped to the Naval Research Lab in the next two weeks, where it will be integrated into the payload. The second arm lags the first by about two months, said Parrish, and is currently in assembly. In 2020, all of the components of the payload will be sent to NRL for assembly into the actual payload. https://www.c4isrnet.com/battlefield-tech/space/2019/10/03/darpa-wants-a-robotic-satellite-mechanic-launched-by-2022/

  Army on path to use space sensors to help guns on the ground see farther

  Jen Judson WASHINGTON — The Army is on a path to use space sensors to help its artillery see and shoot well beyond current capability. The service has already wrapped up an effort to achieve this capability, which took place in Europe in February and March, Gen. Mike Murray, Army Futures Command commander, told reporters in a media call. Murray was discussing how Army modernization would proceed despite COVID-19 social isolation measures in April. The Army will continue to build upon these early successes tapping into space assets to help guns on the ground hit long-range targets, an Army spokesperson told Defense News in a written statement. Conducted through Futures Command's cross functional team in charge of Assured Position, Navigation and Timing (A-PNT), the service was able to link space sensors with shooters in live-fire demonstrations in Grafenwoehr, Germany, on three separate occasions with the latest on March 23, the spokesperson wrote. Over the course of the demonstrations, the team “successfully sensed and hit targets at ranges beyond line of sight using satellite capabilities that have not been accessible to ground forces until now,” the spokesperson said. The exercise showed the “Army's ability to engage and defeat time sensitive targets with timely and accurate fires anywhere on the battlefield.” Tapping sensors that can help guide missiles and munitions to targets deep into the battlefield is critical to the Army's future long-range precision fires capability and key to operating across multiple domains. But achieving such distances requires connecting sensors and shooters that have never worked together before Long-Range Precision Fires (LRPF) is the Army's top modernization priority as it plays a critical role in the future battlefield and will be a centerpiece in the service's future Multi-Domain Operations doctrine currently in development. The LRPT cross functional team will continue to push the capabilities to far greater ranges than previously capable or than those distances previously allowed prior to the United States' withdrawal from the Intermediate-Range Nuclear Forces Treaty in 2019. During the initial live-fire demonstrations, a unit conducted an operation using the weapons and ammunition associated with their mission — in this case the Army integrated the capability with the Multiple Launch Rocket System (MLRS) and the M777 howitzer. The demonstrations used high explosive rounds equipped with a precision guidance kit fuze fired from the M777 howitzer or MRLS launcher. The Advanced Miniaturized Data Acquisition and Dissemination Vehicle accessed various sensors and target data was transmitted through the Joint Automated Deep Operations Coordination System and the Advanced Field Artillery Database System for the technical and tactical fire direction processes, the spokesperson detailed. The demonstrations gave “insight” into current capabilities “and their ability to link in novel ways to provide a capability down to the division operational level of combat,” the Army spokesperson said. Originally, pre-pandemic, the Army had planned to work on the capability throughout the scaled-back Defender Europe 2020 exercise using space-based sensors to pursue deep targets that “have not been responsive to ground forces until now,” according to the spokesperson. The APNT team will build upon the demonstrations by finding ways to reduce the sensor-to-shooter timeline to meet capability needs in the future anticipated operating environments. Ultimately, the Army will integrate the capability into the future Extended Range Cannon and a “full suite of Army fires platforms.” The ERCA cannon has already reached ranges of roughly 40 miles in recent tests at Yuma Proving Ground, Arizona. The service also plans to begin integrating with aviation platforms, the spokesperson said. The demonstrations are feeding into a “targeting process multi-domain operational strategy,” according to the spokesperson. The Army also plans to work on an architecture that connects both kinetic and non-kinetic assets from across joint, interagency and multinational partners. https://www.c4isrnet.com/2020/07/06/army-on-path-to-use-space-sensors-to-help-guns-on-the-ground-see-farther/

  Recalculating: GPS, L-band and the Pentagon’s untenable position on 5G

  Daniel S. Goldin Last week, Ajit Pai, the chairman of the Federal Communication Commission, submitted the L-band Ligado spectrum proposal for approval, which, he said, will “make more efficient use of underused spectrum and promote the deployment of 5G” with “stringent conditions to prevent harmful [GPS] interference.” All five FCC commissioners voted to affirm the proposal, which was formally published in a 70-page report. L-band is a critical piece of spectrum that will help accelerate the deployment of U.S. 5G so we can compete and ultimately win against China. The Department of Defense argues that use of the L-band (as Ligado proposes) will interfere with GPS, which is essential to our military and economy. The FCC's final order concludes that the testing upon which the DoD and other opponents based their GPS interference claims was invalid. L-band opponents' interference measurement (termed 1dB C/No) is “inappropriate” and “there is no connection presented in the technical studies” that prove this measure of interference “relates to performance-based metrics” of a GPS receiver. In short, the FCC said there is no harmful GPS interference, and opponents have been using a flawed methodology and an invalid test with which the FCC “strongly disagree[s].” The FCC's recent report is not the first time the Ligado proposal was determined to cause no GPS interference. In early 2019, the National Telecommunications and Information Administration under David Redl reviewed the Ligado proposal carefully — along with the 20 government agencies that comprise the review body — and determined there is no interference. The NTIA then wrote a recommendation for approval and, before it could get to the FCC, it was blocked, eventually leading to Redl's dismissal. Further, over 5,000 hours of testing, including 1,500 hours at a high-tech U.S./DoD-sponsored and designed facility (performed by the world-recognized standard-in-testing National Institute of Standards and Technology scientists and engineers), proved no harmful GPS interference. Afterward, a DoD expert who monitored and confirmed the testing results told me “there is no interference problem, only a bureaucracy problem.” Yet DoD has continued to blitz the executive and legislative branches, galvanizing opposition with a compelling plea: Ligado hurts GPS, which endangers military operations and will harm the economy. Powerful. But factually wrong. And if wrong, why is Defense Secretary Mark Esper continuing to lobby against the FCC? The FCC is an independent agency. The Communications Act of 1934 charged the FCC with regulating communications for important reasons, including “for the purpose of national defense.” So why is the DoD employing principles of war — offensive operations to mass upon and seize the objective — toward the demise of Ligado's proposal and, perhaps implicitly, Ligado itself? Members of the Senate Armed Services Committee and the House Armed Services Committee are weighing in on the DoD's behalf. They have been presented partial, one-sided information. Mr. Esper is a capable, reform-minded defense secretary who has brought much-needed change to the Pentagon. But he has also been advancing one-sided recommendations from his senior staff for GPS issues, some with longstanding connections to the highly influential Position, Navigation, and Timing Advisory Board — which enjoys a level of influence akin to a special interest group within the U.S. government. A reading of the defense secretary's November 2019 letter to the NTIA reveals that even the DoD was never really sure about its own GPS interference claims, stating merely there are “too many unknowns,” the “risks are far too great,” testing shows “potential for” disruption and the Ligado system “could have a significant negative impact.” Yet, once the Ligado proposal was presented for approval on April 15 — with no new testing or analysis since November — DoD leadership tweeted that Ligado's signal “would needlessly imperil” DoD capabilities that use GPS, and risk “crippling our GPS networks.” If taken at face value, this means the DoD has spent over $50 billion over 45 years on a military GPS system that is so fragile it can be rendered useless by a 10-watt transmitter (a refrigerator light bulb) operating 23 MHz away. If true, this would represent one of the most egregious mismanagements of taxpayer dollars in federal procurement history. The pandemic has shown that China is coercing nations in need of medical assistance to adopt Chinese 5G infrastructure. Coercion from Chinese dominance in 5G would be worse. Agencies like the FCC and NTIA are in the national security arena now. As Attorney General William Barr stated in February, “we have to move decisively to auction the C-band and bring resolution on the L-band. Our economic future is at stake. We have to bear in mind in making these spectrum decisions that, given the narrow window we face, the risk of losing the 5G struggle with China should vastly outweigh all other considerations.” It is time for bold, forward-looking leadership and a wartime mindset. Chairman Pai deserves credit for setting this example. His courageous decision, coupled with support from the FCC commissioners and the strong statements of support from Secretary of State Mike Pompeo and Barr, signals a new determination to win the 5G race. L-band spectrum will enable other key elements of the U.S. 5G strategy and private sector innovation faster than any other option. It also demonstrates that a science-based approach to technology and policy is critical, otherwise we will grind to a near halt on every major decision — like this one — to China's benefit. America is truly “exceptional,” and the envy of every political system the world over, because our system is anchored on the rule of law and institutions that allow stakeholders' competing interests to be adjudicated. All parties have had many years to make their cases. The FCC's world-class scientists and engineers have come to a conclusion. The DoD has no new information; it just does not like the result. After all the internal policy battles are fought, there is only one constituency that matters: the American people and their national and economic security, consistent with U.S. policy objectives grounded in facts. This is why we must embrace this scientifically sound and strategically wise decision by the FCC and move forward, guided by another more apt principle of war: unity of effort. https://www.c4isrnet.com/opinion/2020/04/24/recalculating-gps-l-band-and-the-pentagons-untenable-position-on-5g/
