RF Earth Observation
Listening
beyond what's
visible.
A payload that detects, locates and identifies radio-frequency emitters anywhere on Earth, including the ones that turn their transponders off.

Vessels emit far more than AIS: radars and satcom terminals. We listen for those emissions from space, geolocate the source through Advanced Signal Processing, and turn each signal into a digital fingerprint that follows the emitter wherever it goes.
Space Alma is developing the payload for radio-frequency Earth observation: wide-band receivers that listen across 2–12 GHz (proof of concept) and fly on 6U to 12U platforms. We sell the resulting data (vessel locations, trajectories, RF signatures) to commercial maritime operators, insurers and analytics firms, and to allied governments.
The same sensor that maps illegal fishing in the South Pacific maps sanctioned tankers in the Gulf.
Wide-band detection, edge-side signal processing, geolocation to a 1 km to 5 km radius, and a persistent fingerprint per emitter. Day, night, any weather.
Wide-band software-defined receivers cover marine radar (X/C/S), military radar and satcom in a single pass. 2–12 GHz proof of concept.
We geolocate emitters through Advanced Signal Processing: a fix from a single satellite, no constellation triangulation required.
Every transmitter has a unique signal signature. We extract it, hash it, and tag it back to AIS the moment a vessel turns its transponder on.
GPS positions, trajectories, fingerprints. Lightweight feeds, API-first, ready for the customer's existing maritime or intelligence workflows.
We are developing the payload: wide-band receivers that listen across 2–12 GHz (proof of concept) and geolocate emitters through Advanced Signal Processing. It will fly on 6U to 12U platforms. No constellation needed for first fix.
Our first market is maritime domain awareness, and we expect to expand our use cases from there. The same RF feed serves commercial maritime operators and sovereign agencies, each with their own slice of the data.
A staged path. We prove the payload on the bench, fly it as a demonstrator, and earn signal data from a single satellite before scaling to a five-satellite constellation.
