ECA GROUP’s STR comprise a range of beacon receivers working in different freqeuncy bands for satellite ground station equipment.

ECA GROUP has developed this STEP-TRACKING RECEIVER RANGE IN L- AND X-BAND to track all types of Satellite Communications (SATCOM), either commercial or military satellites.

These beacon receivers are an essential element in the pursuit of a geostationary, low earth orbit (LEO) or medium earth orbit (MEO) satellite. They work in L-band or X-band and can also be configured for other frequency bands upon request.

The STR-Range can be implemented in ground stations, mobile stations or aboard military vessels.  They include a highly stable synthesized oscillator frequency and a down-converter.  They also have an extremely fast locking time.

The STEP TRACKING RECEIVER (STR) RANGE uses the sequential amplitude detection (step-by-step technique), which aims to detect the highest received signal level by incremental motion of the antenna.



  • Delivers DC output voltage proportional to received signal strength
  • Accepts PM or BPSK input modulated carrier and includes an anti-sideband system
  • Has high performance advantage remote control/monitoring achieved via RS232 and ethernet


  • High performance to track all types of satellite communication
  • Flexibility in different types of implementation
  • The step tracking receiver STR-L was initially developed and produced according to a specific customer need. Thanks to its steady and high performance, the STR-L step tracking receiver has been acquired by many other customers.
