Satirim: Towards a Thermal IR Small Satellites Constellation

We present the development of a thermal IR camera for a nanosat In Orbit Demonstration (IOD) mission. The primary objective of the TIR remote sensing mission is Land Surface Temperature (LST) and derived evapotranspiration (ET). On the longer term we aim at building up a constellation of satellites allowing a fast revisit time in the order of one to a couple of days.
