  S.715 SkyTraceR Tracking Transponder

  • The SkyTraceR S.715 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 frequency-selectable, programmable X-band transmitter (within the range 9.2-9.5GHz)

  • It produces a clearly recognisable radar return (‘paint’) on the surveillance radar set

  • Can be set to single or multiple, pulse or swept returns

  • 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

  • Its 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
