SineLink ground-beacon GPS substitute analyzed; EW vulnerability identified

Published

A Russian technical channel reports detailed analysis of a captured Ukrainian SineLink module, finding it is not a radio modem but a navigation beacon for a ground-based SNS (Satellite Navigation Substitute) network — a GPS alternative that remains functional when satellite navigation is jammed. The system works as inverted GPS: beacons with precisely known coordinates are installed on trees or masts and the drone triangulates its position from them. The analysis finds the beacon antenna has pronounced frequency optima rather than true broadband 500 MHz coverage, and that wideband EW can overload the receiver input or destroy a SAW filter — providing a concrete attack vector. The authors warn that captured beacons may be booby-trapped, though no such cases have been recorded yet.
