Passive space-based radio-frequency detection and geolocation of vessels

Passive space-based radio-frequency detection and geolocation of vessels — emissions from onboard communications and navigation equipment captured by a low-Earth-orbit smallsat constellation and converted into geolocation coordinates, timestamps, and RF parameters. The product is a vessel position derived without AIS or any onboard reporting: multiband RF collection in a single pass, all-weather, 24/7, global and beyond coastal-range limits, at kilometre-level geolocation accuracy with low latency. Ships are detected and characterised from their own emissions, so the dataset covers vessels that have disabled or manipulated AIS. A companion Tip & Cue layer records where an RF detection triggered a targeted follow-on observation from optical, SAR, hyperspectral, AIS/VMS/LRIT and other maritime systems.

Dataset card

Type: not stated
Format: Tabular and geospatial — RF detection records (geolocation point, timestamp, frequency band and RF parameters, characterisation attributes) delivered as structured data with standard GIS interoperability and integration into existing maritime surveillance systems; underlying raw RF captures sit behind the derived products
Volume: Request further research — no detection or archive count is disclosed. Scale is bounded by constellation size and revisit: a growing smallsat fleet collecting multiband RF on every pass gives global persistent ocean coverage, so order 10^8-10^9 geolocated RF detections across several years is plausible, but the figure is unverified and accessible archive depth depends on the subscription tier rather than being a fixed dataset size.
Users: B2B and government accounts, not registered users — a subscription data-and-analytics service sold to defense, intelligence, and maritime-authority customers, so the user base is named seats within a limited set of contracted organisations; realistically low hundreds to low thousands across government and commercial accounts (inferred from a funded European NewSpace scale-up with a multi-national customer base)
History: 7 years
Update frequency: not stated
Growth: Active and expanding — the site is current into late 2025/2026 with refreshed assets and an active events calendar, an open careers pipeline, and continued constellation build-out, indicating a scaling rather than mature operator
Launched: ~2019-2021 for first RF detection capability and first commercial data products, on a company founded in 2015, with the current product suite and web presence substantially newer (site assets dated 2025-2026)
