Space Systems Command is seeking a prototype to modernize the SBIRS Consolidated Relay Ground Station and replace obsolete ground-system hardware.
- **Government buyer:** U.S. Space Force, Space Systems Command (SSC); no subordinate office is specified.
- **Requested effort:** Develop a prototype to modernize the Space Based Infrared System (SBIRS) ground architecture and upgrade the Consolidated Relay Ground Station at the Mission Control Station and its backup.
- **Legacy equipment to replace:** Command Telemetry Link Extender (CTLE), IOPlex, and serial cryptographic hardware; the replacement solutions should be modern, supportable, and IP-based.
- **Key technical requirements:** Support the GEO, HEO, and DSP constellation and demonstrate compatibility with Next Generation GEO and future Next Generation Polar constellations.
- **OEMs and vendors:** No OEMs or vendors are identified in the provided materials.

### Description

The project seeks a prototype to modernize the existing Space Based Infrared System ground architecture by replacing obsolete and difficult-to-sustain hardware, including the Command Telemetry Link Extender (CTLE), IOPlex, and serial cryptographic hardware, with modern IP-based solutions. The prototype must expand and upgrade Consolidated Relay Ground Station capabilities at the Mission Control Station and Mission Control Station Backup. It must support the full SBIRS constellation (GEO, HEO, DSP) and demonstrate compatibility with the Next Generation GEO and future Next Generation Polar constellations. Respondents need active NSTXL membership to submit, and the full RPP is available through a Key Document Request form.
