This paper presents the general design and performances of the microwave instruments suite to be embarked on the next generation of Meteorological Operational satellites MetOp-SG. The instruments developed under ESA management are an integral part of the second generation of the EUMETSAT Polar System. The unique frequency range covered reaches from 18 to 664 GHz and is provided by three separate instruments...
In this work, the authors present a suitability analysis of an Extended-Interaction Klystron (EIK) and a Traveling Wave Tube (TWT) to meet the requirements of the Wind-Scatterometer instrument, that will be part of the MetOp Second Generation (MetOp-SG) meteorological mission. Trade-off analyses are presented, common considerations to both technologies are provided and a preliminary analysis on the...
Ice Cloud Imager (ICI) is a microwave/ sub-millimetre wave radiometer that is being developed for MetOp Second Generation Programme. ICI will provide unique frequency range that has never been measured from space using nadir looking instrument.
This paper presents the Microwave Imager (MWI) instrument, a microwave radiometer that is being developed for the MetOp Second Generation Programme. The MWI is a conically scanning radiometer and it will provide, in 2021–2042 timeframe, cloud and precipitation observations, snow and sea-ice coverage as well as gross profiles of water vapour and temperature.
MicroWave Sounder (MWS) is a microwave radiometer that is being developed for MetOp Second Generation Programme. MWS will provide numerous improvements compared to the currently operational microwave sounders.
The global navigation satellite system receiver for atmospheric sounding (GRAS) on MetOp-A is the first European GPS receiver providing dual-frequency navigation and occultation measurements from a spaceborne platform on a routine basis. The receiver is based on ESA’s AGGA-2 correlator chip, which implements a high-quality tracking scheme for semi-codeless P(Y) code tracking on the L1 and L2 frequency...
