RFI - Advanced Satellite Communication Ground Entry Point

The Space Rapid Capabilities Office (Space RCO) has issued a Request for Information (RFI) to explore advanced satellite communication antenna technology for enhanced communication services. This initiative seeks industry insights on a multi-purpose phased array system capable of operating across S-band, L-band, and C-band frequencies, aimed at supporting various missions including Ground Entry Point for satellite communications and telemetry. Key requirements include electronic beam steering for simultaneous effective contacts, high availability (99.9% uptime), security against unauthorized access, modular design for future adaptability, and compliance with Department of Defense (DoD) environmental standards. Interested vendors are asked to submit information on their experience, technical approaches, system designs, security features, transportability options, and production capacities, along with cost and schedule estimations. This RFI is informational and does not guarantee procurement; however, the responses will help shape future procurement strategies. Submissions are due by April 26, 2025, and should not exceed 20 pages. The Space RCO aims to ensure the advancement and reliability of satellite communications to protect space assets and support military operations.

The document provides responses to a Request for Information (RFI) regarding various technical requirements for a satellite communication system. Key topics include beam allocation, modulation formats (primarily QPSK and BPSK), antenna design and performance, reliability standards (minimum uptime of 99.9% for over 10 years), power supply requirements (worldwide compatibility), as well as testing, security, and operational parameters. The system must ensure independent beam assignability and comply with NTIA's spectral mask requirements while maintaining high industry sidelobe standards. Antenna separation must be under 150 feet, and there are strict protocols for maintaining link margins during dynamic operations. Additional specifications include a zero-trust security architecture and the use of a digital IF interface. Significantly, the deployment requires a stringent 24-hour teardown timeframe, and the system is expected to operate across the full frequency range without flexibility in standards or requirements. This reflects the federal government's commitment to ensuring reliable and efficient satellite communication in compliance with established military and operational standards.
