IOT Services

The execution of satellite payload In-Orbit Testing (IOT) is a standard service offered from the Betzdorf facilities in Luxembourg, and includes the following possible activities:

  • Usage of Betzdorf ground facilities for automated payload measurements (state-of-the-art IOT system, antenna and software for maximum automation of the measurements and related reports)
  • Full payload testing specification, coordination and planning
  • Analysis of measurement payload data and performance with web-based reporting
  • Antenna mapping: specification, execution and post-processing

In addition, our latest IOT system allows us to perform remote testing from any location.

Our IOT system performs all the measurements required:

  • Frequency translation
  • Gain transfer curve with/without telemetry
  • Beacon EIRP, center frequency and phase deviation
  • Channel amplifier modes (limiter, linear)
  • Figure of merit (G/T)
  • Group delay and frequency response
  • Attenuator steps
  • Carrier level measurement
  • Spread spectrum based measurements
PFMS_Mapping

All measurements are interactively managed by new-generation software (see products, IOTS 2000) for test scheduling, preparation, execution and web-based reporting.

For antenna mapping, in addition to the standard azimuth/elevation cuts, we offer a special method for assessing the daily variations of the antenna footprints, by using Portable Footprint Measurement Stations (PFMS) located in the high-slope regions of these footprints. Such assessment allows optimisation of the fixed antenna biases compensation, and allows verifying the thermal stability of the satellite antenna system.
