BG 100 — passive hemispheric maritime sensor
The BG 100 gives an Unmanned Surface Vessel its eyes — passive, hemispheric, day/night — without the RF signature of radar. Integrated with AIS and ECDIS to fuse cooperative tracks with what the sensor actually sees. Designed alongside Robosys VOYAGER autonomy.

Why passive matters
See without being seen.
An emitter-free sensor doesn't show up on the threat board. BG 100 builds a surface-traffic picture from optical and thermal energy already in the scene, fused against AIS to flag non-cooperative or spoofed contacts.
