The effort will showcase advanced capabilities that could improve future GPS satellites or inform a new program to augment today\u2019s constellation. Those technologies include steerable beams to provide regional coverage, a reprogrammable payload that can receive upgrades on orbit and protections against signal jamming.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Speaking with reporters during a recent visit to the Space Vehicles Directorate at Kirtland Air Force Base in New Mexico, NTS-3 program manager Arlen Biersgreen said the effort is part of a legacy of experimental positioning, navigation and timing, or PNT, missions that have shaped key military and civilian space technology.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The last NTS satellite flew in 1977 and showcased capabilities that proved integral to the GPS program. Biersgreen said the goal is for NTS-3 to create a pathway for a more regular demonstration cadence.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThe whole team has a vision for this not to be the last NTS in the near future,\u201d he said. \u201cThe reality is \u2014 because of the threats GPS is experiencing and because of the importance that it has to military and civilian operations all over the world \u2014 we\u2019ve got to have a faster cycle to keep up with the threats as they develop.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In preparation for the 2023 launch, Biersgreen and his team expect to finish integrating and testing the spacecraft\u2019s hardware and software this fall in time to deliver the satellite by the end of the year. The program recently completed key tests of major hardware and software components, including antenna arrays and the command-and-control system for the<a href=\"https:\/\/www.c4isrnet.com\/battlefield-tech\/space\/2021\/06\/28\/northrop-grumman-delivers-bus-for-space-forces-experimental-navigation-satellite\/\" target=\"_blank\"> satellite bus and payload<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For the program\u2019s ground segment, which will operate NTS-3 once on orbit, the team is eyeing integrated testing this fall and has ordered the hardware for its eventual mission operations center. In the meantime, the program has set up a mock-mission operations center for training and to ensure the various interfaces and systems work together. Once the real mission operations center is completed later this year, Biersgreen said, the team will use it for a factory compatibility test that will demonstrate functionality between the ground system and the spacecraft.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The program is also developing NTS-3 ground receivers, which allow military users to tap into the satellite\u2019s advanced PNT capabilities. To date, the team has built four receivers and plans to provide six for the NTS-3 experiment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Biersgreen said the program office is also eyeing opportunities to validate NTS-3\u2032s performance during <a href=\"https:\/\/www.c4isrnet.com\/battlefield-tech\/space\/2022\/04\/08\/us-space-force-to-test-experimental-navigation-satellite-in-upcoming-army-exercise\/\" target=\"_blank\">exercises with the military services<\/a>. For example, the team had a chance to validate the receivers\u2019 performance during a March exercised called NAVFEST, which is held annually at White Sands Missile Range, New Mexico. And in August, NTS-3 will be a part of the Army\u2019s yearly PNT Assessment Exercise, or PNTAX.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">During PNTAX, program officials wants to observe how the system works in a real-world environment and identify any necessary changes. The exercise also provides a chance to measure the satellite\u2019s anti-jam capability, giving the Air Force Research Lab a \u201cmore convincing example of the utility of the techniques that we\u2019re demonstrating,\u201d Biersgreen said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Once on orbit, NTS-3 will spend its first year performing more than 100 experiments, which will test various technologies and techniques. When the formal demonstration phase is complete, the satellite will continue to provide data for about two years.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As the lab plans for the experiment, acquisition offices within the Space Force and the Air Force are preparing strategies to buy and field the new technology. The Space Force is in the midst of a force design study that could drive changes to its current PNT architecture, and the serivce closely watching NTS-3 to see how it might augment GPS satellites.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Air Force Life Cycle Management Center is particularly interested in the user equipment segment of the program and is making plans to take advantage of the program\u2019s software architecture.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cWe\u2019re working closely with our mission partners so that the data coming out of the experiment is relevant for transition across space, ground and user segments,\u201d Biersgreen said.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Navigation Technology Satellite-3 will
