L3Harris is the prime contractor of NTS-3 responsible for the design, development, integration and test of the NTS-3 space vehicle. We are also responsible for supporting launch vehicle integration, integration with the control and user segments and on-orbit operations. In addition, L3Harris will deliver novel ground mission applications for the cloud-based, Enterprise Ground Services (EGS)-compatible ground control system. Together with Air Force Research Laboratory (AFRL)-developed reprogrammable, software-defined user equipment, this system demonstrates a multilayer, robust and resilient geosynchronous (GEO) augmentation to GPS to ensure U.S. freedom of operations in air, space and terrestrial domains.
