3.2 Analysis of the contribution There is a general trend for all these measurement; there is an additional gain slope. The elapsed time of this measurement is 20 minutes, for 44 points of measurement. Perturbations could have several origins: - Propagation: variations of propagation conditions in the atmosphere may change during the measurement duration. The higher the frequency, the larger the contribution. - Motion of the satellite combined with antennas gain slope : this results in a modification of the payload antenna pointing to the ground station direction. Its effect depends on the location of the IOT station within the Satellite antenna diagrams. - Ground station stability: thermal RF ground chain stability, antennapointing stability, and measurement equipment stability… - Satellite temperature: RF gain chain during the elapsed time The previous In Orbit Tests have all presented a dispersion of 0.25 dB to 0,5 dB for 3 MHz until 30 MHz bandwidth filter. 3.3 Advantage of the new IOT Gain flatness Measurement method This new method allows to compensate all these medium-term drifts affecting the measurement conditions.
