Paper Abstract
Aquarius/SAC-D is a cooperative international mission conducted jointly by the National Aeronautics and Space
Administration (NASA) of the United States of America (USA) and the Comisión Nacional de Actividades Espaciales
(CONAE) of Argentina. The overall mission targets the understanding of the total Earth system and the consequences of
the natural and man-made changes in the environment of the planet. Jointly developed by CONAE and the Canadian
Space Agency (CSA), the New IR Sensor Technology (NIRST) instrument will monitor high temperature events on the
ground related to fires and volcanic events, and will measure their physical parameters. Furthermore, NIRST will take
measurements of sea surface temperatures mainly off the coast of South America as well as other targeted opportunities.
NIRST has one band in the mid-wave infrared centered at 3.8 um with a bandwidth of 0.8 um, and two bands in the
thermal infrared, centered respectively at 10.85 and 11.85 um with a bandwidth of 0.9 um. The temperature range is
from 300 to 600 K with an NEDT < 0.5 K for the mid-infrared band and from 200 to 400 K with an NEDT < 0.4 K for
the thermal bands. The baseline design of the NIRST is based on micro-bolometer technology developed jointly by INO
and the CSA. Two arrays of 512x3 uncooled bolometric sensors will be used to measure brightness temperatures. The
instantaneous field-of-view is 534 microradians corresponding to a ground sampling distance of 350 m at the subsatellite
point. A pointing mirror allows a total swath of +/− 500 km. This paper describes the detailed design of the
NIRST camera module. Key performance parameters are also presented.
