This Request for Information (RFI) is focused on obtaining access to bandwidth carried by a commercially owned, commercially operated UHF-capable on-orbit MEO satellite for use in a near-term experimental campaign to:
- Characterize spectrum, waveform, and user equipment operation with a MEO UHF system
- Demonstrate interoperability between a potential future MEO UHF system and the existing GEO constellation
- Inform a time-sequenced pathway to augment or replace the GEO UHF system with a MEO capability
The offeror should consider technology solutions that prioritize existing space vehicle, payload and communications link capabilities to provide on-orbit service immediately or as soon as possible. An Initial Launch Capability (ILC) by 2030 is potentially useful, but innovative approaches leading to earlier on-orbit capability are strongly desired. The Government recognizes that this initial prototype may not be fully representative of a final, future architecture, but rather represents an initial step to explore providing UHF services from MEO.
