Abstract

In 2023, Hydrosat will launch its VanZyl-1 land mapping mission and substantiate accurate and timely thermal infrared (TIR) data from a commercial SmallSat platform. Science and applications communities have made clear the needs and requirements for daily, field-scale land surface temperature and evapotranspiration data. Hydrosat’s eventual SmallSat constellation will significantly advance our monitoring and management capabilities for ecosystems, agriculture, and other applications. VanZyl-1 includes a primary TIR payload with a projected ground sample distance (GSD) of 70 meters, and secondary visible through near-infrared multi-spectral payload with a GSD of 30 meters. The TIR payload incorporates a modern microbolometer Focal Plane Array (FPA) with telescope, thermal control, and calibration subsystems designed for optimal performance within a total payload volume of approximately 16U. The payloads will be hosted on an “ESPA-class” SmallSat in partnership with Loft Orbital, and operated as part of a demonstration mission with up to 5-year planned lifetime.
