Concept of modularity is fast picking up in small satellites due to the ever-increasing user demands for cartographic
applications at cadastral level, urban and rural management,
coastal land use and regulation, utilities mapping and
development and various other remote sensing application.
Modularity will enhance the ability to launch a new satellite
within few weeks of user's request. Thermal design of small
class of satellites is quite challenging due to its space and
power constrains. To meet this challenge the thermal design
has to be simple and robust. Traditionally, the TCS is
vigorously designed, analysed and optimised for every satellite
mission. The next generation satellites demand a more modular
thermal control system to meet the wide range of mission
requirements. With various boundary conditions and flight
uncertainties it is a must to account these factors. In the
satellite, temperature requirements of battery are typically
narrower that other surrounding elements. This paper describes the modular approach of thermal design for batteries in small class of low Earth orbit satellites suitable for various
inclination orbit
