The U.S. Space Force/Space Systems Command is conducting market research for a modernized GPS Ground Control Segment Monitor Station Service to replace legacy AEP monitor-station data feeds and support resilient PNT, CNAV, and MNAV/M-Code operations. The desired solution must provide simultaneous multi-frequency, multi-code tracking across legacy, modernized civil (L2C/L5/L1C), and military M-Code signals for up to 63 space vehicles, with MOSA/API integration, safety-of-life assurance, NSA-compliant cryptographic/security handling, FSET certification, and sustainment for globally distributed remote monitoring sites. The Government envisions phased operational acceptance: Phase 2.1 replacing P(Y) data feeds by late 2028, Phase 2.2 delivering remaining core capabilities by late 2030, and Phase 2.3 additional capabilities desired by CY2032. Respondents should address incremental delivery, urgent operational need continuity, accelerated T&E/DevSecOps, technical baseline transition, and lifecycle obsolescence management ensuring >98% availability through at least CY2035. The acquisition anticipates delivery of the software baseline and technical data rights to the Government, with industry input requested on ROM cost, delivery model, contract type, GFE/GFI needs, and optional future capabilities.

The Space Force is conducting market research via a Sources Sought/RFI only and will not award a contract based on responses, seeking industry capability for an integrated, secure, safety-certified Monitor Station Service supporting GPS Ground Control Segment modernization and replacement of legacy monitor station receivers. The solution must track legacy, modernized civil (CNAV L2C/L5/L1C), and military M-Code signals across up to 63 space vehicles; integrate with AEP/Kalman Filter; use MOSA APIs; meet DO-278A/DO-178C assurance up to DAL D; support NSA cryptographic, RMF IL5/IL6, and FSET security requirements at globally distributed SECRET-cleared sites. Phased targets include replacing the operational P(Y) data feed by late 2028, delivering remaining core CNAV/MNAV and security capabilities by late 2030, and delivering additional capabilities desired by CY2032, with sustainment and obsolescence management through at least CY2035 and >98% availability. The Government intends to acquire the software baseline and technical data rights and seeks industry feedback on technical maturity, schedule feasibility, ROM cost, delivery model, contract type, and GFE/GFI needs. A DOD-approved SECRET facility clearance is required for ground segment integration testing and operations, and respondents should provide verifiable evidence of mature TRL 6+ components and relevant GPS ground/receiver experience.
