SevenStar Electronics S.705 Radar Tracking Transponder • The SkyTracerTM S.705 Radar Tracking Transponder from SevenStar Electronics Ltd has been designed to achieve accurate and reliable tracking or secondary surveillance of objects using commercially available, low cost X-band radar sets • It features an X-band radar receiver, and a frequencyselectable, programmable X-band transmitter (within the range 9.2-9.5GHz) • It produces a clearly recognisable radar return (‘paint’) on the surveillance radar set • It has been designed using commercial off the shelf (COTS) components, and is the result of many years experience in the specification, design and manufacture of marine radar transponders (SARTs – Search And Rescue Transponders) and related marine safety equipment. It brings together the ultimate in high-reliability design and modern manufacturing techniques • Its exceptionally low power consumption and small size make it ideal for tracking objects such as drones and other UAVs without affecting their usable payload or performance unique digital design brings new levels of sophistication and programmability to suit varying needs, and also gives guaranteed lifetime performance, reduced component count and increased reliability SevenStar Electronics Ltd.
