RF Sensing and Signals Intelligence from Commercial Satellites
What do radio-frequency sensing satellites detect, who buys their data, and how large can this segment become?
Chapter summary
RF sensing satellites listen for radio emissions (ship and aircraft radars, satellite phones, push-to-talk radios, GPS jammers) and locate them by measuring signal timing and frequency from several satellites.
Key takeaways
- 1
HawkEye 360 (39 satellites in orbit on Setcoin's count), Unseenlabs (France) and Kleos (Luxembourg) are the main commercial operators.
- 2
Their data finds dark vessels (Chapter 33), maps GPS jamming in conflict zones and supports spectrum monitoring.
- 3
Buyers are almost entirely governments and defence.
