Final receivers for MetOp-SG delivered
30 Jun 2023
RAL Space has delivered the last of 20 millimetre wave receivers developed for the Microwave Sounder and Microwave Imager instruments on board the MetOp-Second Generation satellites.
MetOp Second Generation (MetOp-SG) is a programme of six weather satellites led by the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), which will be launched between 2024 and 2039 in three successive pairs. RAL Space has delivered a total of 20 flight-ready millimetre wave receivers which will fly across the six satellites.
The RAL Space team, led by the Millimetre-wave Technology Group, designed, manufactured and tested the receivers which will support global weather forecasting and climate monitoring.
Compared to their MetOp predecessors, MetOp-SG satellites will have a wider range of payloads providing increased observational capability with improved sensitivity, thanks in part to RAL Space’s state of the art millimetre-wave technology. The new MetOp-SG receivers will deliver improved atmospheric temperature and humidity data to meteorologists, resulting in more accurate weather forecasts, and better prediction and tracking of extreme weather phenomena.
The receivers and components have been delivered to three Airbus Defence and Space sites in the UK, France & Spain, where some have already been integrated onto the satellites’ instruments and undergone further testing.

Dr Simon Rea, Lead Engineer on the programme at RAL Space added: “Having worked on the MetOp-SG mission from the first feasibility study starting in 2007, I am delighted to have reached the milestone of the final flight receiver delivery to our customers in this phase of the programme. I’d like to thank the entire team within RAL Space whose expertise and dedication have made this possible. We are now collectively looking forward to the satellites becoming operational and the impact the data will have on weather forecasting and climate modelling.”
Further involvement with MetOp-SG
RAL Space has also supplied a further 9 millimetre wave receivers to Radiometer Physics GmbH, Germany, for use on the MetOp-SG’s Ice Cloud Imager instruments.
