    Push for naval ‘interchangeability’ will require help from industry

    The U.S. Navy and its closest allies and partners continue their quest to become interchangeable, but they can’t do it without international supply chains.

  • Is near-instant satellite imagery almost here?

    Is near-instant satellite imagery almost here?

    By: Mike Gruss Intelligence analysts and soldiers on the battlefield could have access to near real-time imagery from commercial satellites as soon as 2021 thanks to new industry partnerships. Amazon Web Services unveiled Nov. 28 a new product named AWS Ground Station, which includes parabolic antennas at 12 locations across the globe. Those ground stations can download imagery data as satellites pass overhead and then push that information to the cloud at faster speeds than traditional ground stations. Meanwhile, leaders from satellite imagery company DigitalGlobe said in tests they were able to move imagery data from the ground station to the cloud in less than a minute. Using today's technology, that task takes about an hour. Combined, the speed of the new ground stations and the expected launch of DigitalGlobe's constellation of next-generation imagery satellites in 2021 would offer a new level of immediacy to customers. “When firefighters are attacking a wildfire, they need the most up-to-date information to save lives and homes,” Jeff Carr, director of mission operations engineering support at DigitalGlobe, wrote in a Nov. 27 blog post. “When first responders are tracking down refugees fleeing danger in flimsy rubber boats, they need real-time information about where those rubber boats are located before they sink. The uses for current and accurate space-based data is growing — and the end-users need it quickly.” DigitalGlobe provides imagery to the National Reconnaissance Office under the Enhanced View contract and to the National Geospatial-Intelligence Agency with the Global EGD contract. Several companies that already provide imagery and data to the Department of Defense and intelligence community — including BlackSky, Spire and HawkEye 360 — are also using the ground stations. Traditionally, ground stations download information from satellites on a rigid schedule, meaning users must wait several hours until the next pass when new information is available and can be processed. The company's new Legion satellites will double the number of times the satellites contact ground stations. In addition, an imagery satellite could revisit the same target as many as 15 times a day. All of that means defense and intelligence agencies could have access to imagery that is a few minutes old, not several hours old. Turner Brinton, a DigitalGlobe spokesman, declined to comment on the technical aspects of how the company would support the U.S. government. “Satellite data is incredibly useful for building a wide range of important applications, but it is super complex and expensive to build and operate the infrastructure needed to do so,” Charlie Bell, senior vice president of AWS, said in a press release. “Today, we are giving satellite customers the ability to dynamically scale their ground station antenna use based on actual need. And, they will be able to ingest data straight into AWS, where they can securely store, analyze and transmit products to their customers without needing to worry about building all of the infrastructure themselves.” In addition, Lockheed Martin and Amazon Web Services announced a new partnership Nov. 27 that would allow customers to download satellite data faster, more often and from multiple satellites at the same time. That technology is a shoebox-sized antenna and satellite receiver known as Verge. Each antenna would cost about $20,000 and replace larger parabolic antennas, which are often priced at more than $1 million. While Pentagon officials have worried that larger ground stations for military satellite could make easy targets, the relatively small size of Verge could be an attractive feature to defense officials focused on resiliency. It's unlikely the Defense Department would rely on the new technology for its satellite downlinks, but Lockheed Martin leaders said they could envision the military would use the ground stations for experimental satellites, particularly those in low-Earth orbit. Or the technology could be used to create a backup ground station for some of the Pentagon's more sophisticated satellites. Already, Lockheed Martin has tested a network of 10 S-band antennas in the Denver area that downlinked from a small satellite from the Air Force Research Laboratory, said Rick Ambrose, Lockheed Martin's executive vice president for space. In addition, the company has also downlinked data from another, unspecified government satellite and sent that data to the agency's cloud. https://www.c4isrnet.com/intel-geoint/2018/12/03/is-near-instant-satellite-imagery-in-the-near-future

  • Air Force needs more data before making a decision on enhanced KC-46 vision system

    Air Force needs more data before making a decision on enhanced KC-46 vision system

    Kent Miller and Valerie Insinna WASHINGTON — Within a few weeks, the Air Force will have the data it needs to make a decision on whether to install an interim version of the KC-46′s troubled remote vision system, the head of Air Mobility Command said in a Sept. 10 interview. In April, the Air Force and KC-46 manufacturer Boeing signed off on an agreement to replace the tanker's Remote Vision System — the series of cameras that provide imagery to the boom operator during refueling operations — with a newly designed system, called Remote Vision System 2.0. Boeing has agreed to develop and install RVS 2.0 on its own dime, but it has also proposed installing an enhanced version of the original system, eRVS, before then. But AMC commander Gen. Jacqueline Van Ovost, who viewed a demonstration of the eRVS system during a Sept. 4 visit to Boeing Field in Washington state, isn't sold on the upgrade just yet. “The most important thing is, we cannot slow down getting RVS 2.0 into the airplane. So eRVS can't slow us down if we were to accept parts of that,” she told Air Force Times. “And then we want to make sure if we're going to put it on the airplane, that it actually gives us some tangible capabilities with respect to boom operator workload and capability with respect to opening up the envelope for actually doing operational air refueling, or it gives us a great enhancement getting ready for 2.0.” The Air Force and Boeing began flight testing the eRVS this summer. The demonstration shown to Van Ovost, which compared the original RVS to the enhanced version, revealed “some sharpening of the picture with respect to how the boom operator saw the airplane” in day and nighttime conditions, she said. But those improvements in image quality need to be weighed against the time it will take to retrofit the existing KC-46 planes in service with the new eRVS components. “Do we have to ground airplanes for a while to put the put the modifications in?” Van Ovost said. “What's the worth of the modifications compared to the operational envelope it's going to open up for our boom operators?” The Air Force is set to receive the full set of test data within the next few weeks. Once it has the answers to those questions, the service will be ready to decide whether to field eRVS. If the Air Force decides to incorporate the enhanced system, Boeing can start making those upgrades in the second half of 2021, said Mike Hafer, Boeing's global sales and marketing lead for KC-46. Boeing also remains on track to incorporate RVS 2.0 on KC-46s coming off the production line in late 2023 or early 2024, he said. The Air Force intends to purchase 179 KC-46s during the program of record. The first tanker was delivered to the service in January 2019. Boeing is locked into paying any costs associated with the KC-46 that exceed the $4.9 billion firm fixed-price ceiling on its 2011 contract with the U.S. Air Force. So far, Boeing will have spent more than $4.7 billion in company funds on the KC-46 program — almost equivalent to the Air Force's own investment in the program. The deal on RVS 2.0 capped a yearslong dispute over the original system, which the Air Force argued did not provide enough fidelity to boom operators in certain lighting conditions, resulting in incidents of operators accidentally scraping the boom against the receiver aircraft. Van Ovost said the main goal of the trip to Boeing Field was to better understand the progress on RVS 2.0 and whether the final design specifications agreed to in April would meet the needs of tanker operators in the field. Van Ovost described the performance of the original RVS as something the Air Force “couldn't live with” but said she “was pretty encouraged about the collaboration of the team, and how far they've gotten with the requirements of RVS 2.0.” “I'm encouraged that we are on a path to get a fully qualified tanker,” she added. https://www.defensenews.com/digital-show-dailies/afa-air-space/2020/09/16/air-force-needs-more-data-before-making-a-decision-on-enhanced-kc-46-vision-system/
