In this paper we describe the design and development of the Command and Data Management System (CDMS) of the nano-satellite of IIT Madras, named IITMSAT. The CDMS module uses a 32-bit ARM microcontroller from Freescale — KL46Z256VLL4. This module is responsible for decoding the telecommands sent from the ground station, and transmits the time-stamped payload data back as telemetry packets. The SD...
In this paper, we describe the design and development of Flight Computer module of the nano-satellite of IIT Madras, named IITMSAT. The flight computer module uses a 32 bit ARM microcontroller from Freescale-KL46Z256VLL4 and handles the attitude control, beacon transmission and electrical power management functions. The data from the attitude sensors is used by the control algorithm to calculate the...
