The SATCROSS project is a space mission aimed at observing low atmosphere water vapor. The application of Normalized Differential Spectral Attenuation (NDSA), an active differential measurement technique, to co-rotating LEO satellites allows the assessment of 2-D (3-D) water vapor fields over vertical sections of the troposphere on a continuous time basis.
PICOSATS involvement is twofold. On the one hand, satellite formation flying requires an accurate configuration between transmitting and receiving CubeSats that exchange a RF signal: to this end, PICOSATS elaborates mission analysis and constellation architecture optimisation. On the other hand, the observable RF signal requires purpose-built onboard payloads: thence, PICOSATS designs and develops the scientific transmitter and receiver.
