U.S. forces, NATO and international allies rely on the capability for real-time data exchange.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The agency has been working with the FAA to get approval <a href=\"https:\/\/www.c4isrnet.com\/battlefield-tech\/space\/2023\/11\/28\/space-development-agency-demonstrates-link-16-satellite-connectivity\/\" target=\"_blank\">to test Link 16 over national airspace<\/a>, but the process has taken longer than anticipated.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cPrimarily, the FAA wants to make sure that we have compatibility features that are tested on our satellites so that we can\u2019t interfere with any radio navigation aids,\u201d SDA Director Derek Tournear said during a March 6 Space News webinar. \u201cThat makes sense, and we\u2019re working with the FAA to get a plan in place to do that.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Defense Department established SDA in 2019 to build a<a href=\"https:\/\/www.c4isrnet.com\/battlefield-tech\/space\/2023\/04\/04\/space-development-agency-enters-demonstration-phase-after-first-launch\/\"> constellation of low Earth orbit transport and missile tracking satellites<\/a> on rapid timelines, augmenting constellations of large spacecraft with hundreds of small, relatively low-cost satellites. Those spacecraft make up what SDA calls its Proliferated Warfighter Space Architecture and will serve as the data backbone for joint, multidomain command-and-control capabilities.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.c4isrnet.com\/battlefield-tech\/space\/2023\/04\/04\/space-development-agency-enters-demonstration-phase-after-first-launch\/\" target=\"_blank\">After launching its first satellites last April<\/a>, SDA had hoped to move quickly to validate the capability and integrate it as part of large-scale Defense Department exercises, <a href=\"https:\/\/www.c4isrnet.com\/battlefield-tech\/c2-comms\/2023\/05\/24\/lockheed-paces-jadc2-information-sharing-at-northern-edge\/\" target=\"_blank\">like Northern Edge<\/a> \u2014 a joint training event conducted in the Gulf of Alaska.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Instead, the agency opted to perform initial tests over international waters, starting in November. During the initial demonstration, three satellites built by Denver-based York Space Systems transmitted signals from low Earth orbit \u2014 about 1,200 miles above Earth \u2014 to an international test site.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Air Force\u2019s 46th Test Squadron supported the mission from the ground.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">SDA<a href=\"https:\/\/www.c4isrnet.com\/battlefield-tech\/space\/2024\/02\/14\/pentagon-launches-six-satellites-to-boost-missile-tracking-capability\/\" target=\"_blank\"> now has 27 satellites in orbit<\/a>. Those spacecraft are not only equipped to communicate through Link 16, but also have what are called optical inter-satellite links that allow them to share data with one another.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">SDA first tested those inter-satellite links in 2021 during a demonstration<b> <\/b>mission with the Defense Advanced Research Projects Agency called Mandrake. Tournear said the agency has begun to test<b> <\/b>the capability with the first batch of satellites it launched and expects to expand<b> <\/b>that across the constellation later this summer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As the agency works to test and demonstrate<b> <\/b>the capabilities of its first tranche of satellites, it\u2019s also preparing for its next launches, which are expected to begin in September. That mission will set off a nearly yearlong campaign to launch around 161 satellites from Vandenberg Space Force Base in California.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cWe expect to have at least one of those launches by the end of this calendar year and then the rest will essentially be as fast as we can get them through the payload processing facilities,\u201d Tournear said.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The agency has been working with the FAA to get approval to test Link 16 over U.S. airspace, but the process has taken longer than
