What this contract is for

Agency: DEPT OF DEFENSE / DEPT OF THE AIR FORCE
Location: El Segundo, CA
Scope: Federal

Background: Space Systems Command Space Reconnaissance and Surveillance Branch (SSC/SYZ) is finalizing the SG-XX communication architecture requirements and requests industry information on possible high Technology Readiness Level (TRL) solutions to support the constellation of SG-XX vehicles.

SG-XX is a planned super sync geo-based surveillance system comprised of a proliferated constellation of free flyer space vehicles (SVs) with Wide Field of View (WFOV) Electro-Optical (EO) payload(s) capable of wide-area volume search and track.

The primary objective of this proliferated constellation will be to scan, track, and detect Resident Space Objects (RSO's) in and around the geosynchronous orbit geo-belt.

The data collected must be delivered to the operational community in near real time to support warfighter requirements.

The government has performed communication architectures studies and has determined a SG-XX to SG-XX cross link solution will provide the timeliness required to ensure mission data delivery over the entire geo-belt.

The SG-XX constellation will operate in an evenly spaced “string of pearls” configuration at a TBD altitude above the geo-belt.

The cross link may operate in either half-duplex or full-duplex mode between each satellite.

The SG-XX satellite may slew throughout the day to meet the scan requirements and thus the communication subsystem must include antennas that can maintain the link through nominal slew rates.

The solution must incorporate the capability to manage the data flow of each communication element across the constellation of SG-XX satellites.

This RFI is only seeking information related to a radio frequency (RF) V-Band cross link solutions, please do not submit alternative communications subsystem (e.g. optical, other RF bands, or geo to g...

How to bid on this

This is a contract solicitation, not a grant. To bid, you submit a proposal (usually a price and a description of how you would do the work) directly to the government, through the channel the official listing specifies, not through Oppward.

Make sure your business has an active SAM.gov registration. You cannot be paid on a federal contract without one.
Read the full solicitation on the official listing above, especially the scope of work, not just this summary. Our guide to reading a solicitation walks through what to look for.
This listing has no set-aside restriction ("full and open competition"), meaning any business, large or small, can bid.
Submit your proposal by the deadline, using the exact submission method the official listing states. A technically on-time bid sent the wrong way is often treated as late.
