Tranche 3 Ground Entry Point (GEP) Development and Integration

Description: Seeking information on potential sources for GEPs in support of the SDA Tranche 3 constellation. The contractor will be responsible for performing GEP site civils, procurement, installation, integration, test and verification of GEP site communications shelters, antennas and antenna electronics, optical terminals and optical electronics, and GEP site networking equipment and software at multiple, globally dispersed, GEP installations. These installations will provide terrestrial links with SDA’s Tranche 1,2, and 3 constellations through a mixture of Optical Communication Terminals (OCTs), RF Ka-band communication, and backup capability in the form of S-band for Telemetry, Tracking, and Command (TT&C). All GEPs are intended to provide autonomous SV communication in response to scheduled contacts as coordinated through the Ground Resource Manager (GRM) and the local site controller. The GRM maintains constant communication with each GEP to configure contacts, confirm GEP status, and relay contact metrics. As the terrestrial link to a proliferated communications constellation, the GEP transmits uplink commanding to the Space Vehicles (SVs) and relays received data back to the Operation Center (OC) for decryption and routing to end users through secure channels.
