Steerable 3m antenna used for satellite tracking

How is the RF Payload Systems Laboratory equipped?

The RF Laboratory is equipped with:

Multipaction facility and RF Corona facility - thermal-vacuum chambers with precisely controlled temperature and pressure control.

'Passive intermodulation' (PIM) facility – used for interference testing of microwave system elements.

Ultra-stable reference signal – for time and frequency testing, also made available to the ESA Telecom and Radio Navigation Laboratories- one active maser and three caesium atomic clocks.

Life testing facility – accelerated and long-term testing of TWTAs, SSPAs, oscillators with thermal chambers.

General microwave and MMIC testing facility – for general purpose testing of microwave and millimetre-wave modules, includes thin film rapid prototyping for testing.

The Radio Navigation Laboratory is equipped with:

  • Galileo/GPS/GLONASS simulators - with interference generator.
  • GIOVE-A/B simulator – for testing of ground segment receivers.
  • ORUS software - for the analysis of digitally captured real signals.
  • IMAGE software - to generate EGNOS performance data for general public.
  • Formation flying test bed - to evaluate proposed implementation of satellite formation flying.
  • High-gain dish antenna - to track individual navigation satellites without interference.
  • Mobile in-the-field test equipment - for measuring localised interference and multipath.

The RF Remote Sensing Laboratory is equipped with:

  • Instrument modelling software – for SAR performance assessment and design
  • SAR digital calibration transponder – for assessing in-flight performance of SARs
  • Active array/front end simulators
  • PARIS orbit assessment software
  • GNSS-R simulator – for examining the end-to-end performance of GNSS-R instruments operating over the oceans, including PARIS
  • OceanPal instrument – for carrying out external experiments into PARIS and GNSS-R such as soil moisture monitoring
  • SIRA – Simulator for Interferometric Radar Altimeters – combines a state-of-the-art ocean model, ocean scattering module and radar instrument characteristics for performance assessment and design of wide-swath ocean altimeters
  • Cloud and rain radar test bed - which makes use of an arbitrary waveform generator for assessing the performance of ultra-low sidelobe radar waveforms

The ESA Telecom Laboratory is equipped with:

  • Interactive Satellite Networks consisting of gateways and satellite interactive user terminals with star and mesh connection capabilities.
  • Uplink stations in Ku, C and Ka frequency bands
  • Satellite Capacity
  • Network simulation and emulation facilities
  • Wideband satellite channel Simulators and DVB-S2 Test Bed
  • High-speed data link test beds for Earth observing and Telecom applications.
  • Test Equipment for multimedia applications, such as video conferencing end points, collaborative working platforms, video streaming equipment
  • Two test vehicles, one for broadband/mobile communications and the other for interactive broadband communications
