About
About Quadsat
Quadsat develops drone-based systems for testing radio-frequency antennas in their installed environment. A calibrated payload flies a programmed pattern around an antenna and samples its radiation characteristics, replacing some measurements that otherwise require cranes, towers or fixed test ranges.
Flight-control and RF software synchronise position with amplitude and phase data to produce antenna patterns and identify alignment or performance faults. The system serves satellite ground stations, defence radars, wireless networks and broadcast sites. Quadsat supplies the aircraft, measurement payload, planning tools, processing and operator training as an integrated test workflow.

Timeline
Events
- 2026-08-20 - Demonstration - Quadsat demonstrates airborne RF detection and geolocation at DALO Industry Days
The live demonstration took place on August 20 during the August 19–20 event. SpectraLoc detected radar emissions from Karup Airport and converted the airborne measurements into electromagnetic intelligence. Quadsat presented SpectraLoc as a platform-agnostic payload that can integrate across unmanned aircraft selected for mission range, endurance and operating requirements.
Source - 2026-03-26 - Capability - TEKEVER integrates Quadsat SpectraLoc EW payload on AR3 EVO
TEKEVER and Quadsat completed flight integration tests of the SpectraLoc payload aboard the AR3 EVO tactical UAS. The integration enables passive detection, identification, and geolocation of radar emitters without the aircraft broadcasting its own signal. The tests validated interoperable airborne RF sensing on TEKEVER's modular platform in live flight conditions.
