The articles in this segment of the Satellite 101 Wiki have been contributed by Sumit Agrawal, Sanket Chirame, Anant Joshi, Ravit Anand, Ram Milan Verma, Sukanya Kudva, Keshav Janyani, Eashan Gupta and Charit Verma, all of whom are a part of the Attitude Determination and Control Subsystem of Advitiy, IIT Bombay's 2nd Student Satellite
The Attitude Determination and Control Subsystem (ADCS) is very essential for stabilizing the satellite in orbit and ensuring that it points in the direction it is supposed to point in. For a systematic understanding the functions and various components of ADCS, we have organized the contents in a systematic manner as shown below:
- Introduction to ADCS
- Components of ADCS
- Sensors and Estimators
- Actuators
- Control Law
- Propagation
- On Ground Simulations
