Abstract

This paper describes and tests a mathematical model of the REMS GT-sensor (Ground Temperature), which will be part of the payload of the NASA MSL mission to Mars. A short review of the instrument most critical aspects like the in-flight calibration system and the small size, are presented. It is proposed a mathematical model of the GT-sensor based on an energy balance theory, which considers the internal construction of the thermopile, and allows the designer to model independently the change in any of its parameters. The instrument includes an in-flight calibration system which accounts for dust build up on the thermopile window during operations. Pre-calibration tests of the system are presented, demonstrating the good performance of the proposed model, as well as some required improvements.
