Testbed for SatCom on the Move

FORTE SatCom on the Move (SOTM)

Key Features of the Far Field SOTM Testbed at a Glance

Tests/measurements:

  • Antenna pattern
  • Positioning, Acquisition, and Tracking (PAT) performance
  • Residual off-axis emissions
  • Forward/Return link performance
  • End-to-end link performance
  • Fading of the LMS channel including satellite signal impairments
  • Mechanical movement of the terminal platform
  • Realistic GPS/Galileo HF signal over the air (arbitrary tracks possible)
  • Interference from satellites in adjacent positions

Suited for:

  • Ku-Band (12/14 GHz) or Ka-Band (20/30 GHz)
  • Dual-linear or dual-circular polarization

Advantages of the testbed:

  • Higher accuracy of depointing measurements compared to satellite to terminal
  • Precise depointing measurement in azimuth and elevation
  • Cost-efficient and available all the time
  • Far field radiation pattern measurements
  • Weather independent

Our service offer:

  • EUTELSAT SOTM type approval including pattern measurement for ESOG 120
  • GVF type approval measurements for e.g. GVF 101, GVF 104, GVF 105 as an ATE (Authorized Test Entity)
  • Consulting for SOTM systems
  • SOTM system integration (e.g. mobile satellite backhaul solutions in conjunction with a mobile LTE femto cell)
