What this contract is for

Engineers at Los Alamos National Laboratory have developed a “license plate” for satellites to help solve the growing problem of space traffic management. The Extremely Low-Resource Optical Identifier (ELROI) is a simple, easy-to-fly, solar-powered beacon that can be attached to a satellite for tracking. Each ELROI unit transmits a custom identification number that can be read from the ground using signal processing techniques also developed at Los Alamos. The Challenge: Identifying space objects after launch remains a persistent challenge. When dozens of satellites are deployed simultaneously, determining which object is which using traditional radar or optical tracking methods is slow, error-prone, or sometimes impossible. This lack of real-time, reliable identification hinders satellite commissioning, increases operational risk, and undermines space traffic management efforts. Unidentified satellites are particularly problematic after their radio systems are disabled or fail. Without continuous, verifiable identification, defunct satellites add uncertainty to orbital catalogs and increase the risk of collision. Problems Solved: ELROI solves the space object identification problem by providing an autonomous, low-cost, optical beacon that broadcasts a unique ID from orbit. ELROI: enables definitive post-launch identification of satellites faster than conventional means; operates without RF emissions, making it ideal for use even after satellite deactivation; functions autonomously, activating and broadcasting without requiring power or communication from the host spacecraft; and continues operation even after satellite passivation, offering a persistent identity signal over the object’s orbital lifetime. In 2024–25, ELROI was demonstrated successfully on LaCE-1 and R5-...

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.
Check the set-aside listed above and confirm your business actually qualifies for it before you spend time on a proposal. See our guide to set-asides if the category is unfamiliar.
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.
