CSDA Vendor – Hydrosat
NASA Science ·
Hydrosat operates a two-satellite (VanZyl-1 and VanZyl-2) constellation outfitted with two Earth-sensing instruments, a Longwave Infrared Imager (LIRI), and a Visible Near Infrared Imager (VIRI), collecting coincident 30-meter Visible Near Infrared (VNIR) and 70-meter Long Wave Infrared (LWIR) imagery, across a broad 70-kilometer (km) field of view. Because it can measure changes in temperature over […] The post CSDA Vendor – Hydrosat appeared first on NASA Science .

Hydrosat operates a two-satellite (VanZyl-1 and VanZyl-2) constellation outfitted with two Earth-sensing instruments, a Longwave Infrared Imager (LIRI), and a Visible Near Infrared Imager (VIRI), collecting coincident 30-meter Visible Near Infrared (VNIR) and 70-meter Long Wave Infrared (LWIR) imagery, across a broad 70-kilometer (km) field of view. Because it can measure changes in temperature over time, day and night, Hydrosat’s thermal infrared data has the potential to increase agricultural production and improve water management with early water stress detection, identify localized urban heat impacts and urban heat island effects, detect geohazards such as volcanic activity, and monitor emissions and activity signals at industrial sites.
