18 Feb 2022: Unseenlabs released a press report noting its ability to locate and identify Chinese vessels not using the internationally mandated Automated Information System (AIS) and subsequently disappearing from tracking systems normally used in maritime transport. Using its constellation of 4 (now 5 after 13 Jan 2022) LEO satellites Unseenlabs conducted an 8 day satellite acquisition campaign in the South China Sea. Marketing Video

– Unseenlabs conducted its collection activity from 11-18 Nov 2021 to highlight ships missing from AIS monitoring screens.

– According to Vesselsvalue, ships broadcasting AIS signals from Chinese waters has dropped 90% in the past year.

– Chinese authorities invoke national security and sovereignty issues citing the use of foreign intelligence agencies and companies using AIS to keep track of Chinese military vessels and gather sensitive economic data.

– Using its commercial radio frequency (RF) tracking sensors, Unseenlabs reported that they were able to locate 80% more ships using RF collection than solely relying on AIS broadcast. This difference is likely the result of AIS beacons being turned off or having their data transmission blocked by Chinese authorities.

– The company did not reveal any further details.

– Unseenlabs uses proprietary onboard satellite technology and states they can geolocate any vessel at sea, in near-real time, to within a kilometer, from a single nanosatellite.

– Unseenlabs’ service, focused on radio frequency geolocation of ships at sea, has been active since the first satellite launch – BRO-1 – in August 2019.

– Each new launch (2 in 2020, 1 in 2021) has increased the service’s capabilities, notably by increasing its responsiveness and the amount of data produced.

– Rocketlab launched the first three Unseenlab satellites the 4th was on a Vega rocket and the 5th on SpaceX’s Transporter 3 mission.

– The satellites are <=10-kg and travel at 7 km/sec around the Earth at altitudes between 500-550km at apogee. All operate in a sun-synchronous orbit with the exception of BRO-1 which is inclined at 45.0 °.

– Each new satellite will improve the revisit time and generate more data for pattern analysis.

– The company intends to create a constellation of 20-25 satellites.

The financing, development, deployment and operations of small satellites constellations such as Unseenlabs RF interceptors could augment nation-state collection operations. Future collaboration between commercial space operators will deliver further insights on surface activities. RF intercept/geo-location data could cue imaging satellites, such as those from Planet or Capella, to identify a vessel’s identity and mission.
