Swayam

Swayam is a 1-U picosatellite (CubeSat) developed by the undergraduate students of College of Engineering, Pune.

[2] They have successfully completed assembly of the flight model having a size of 1-U and weight of 990 grams under the guidance of Indian Space Research Organisation (ISRO) in January 2015.

The team consists of students from freshers to seniors and spans all the engineering disciplines in the college.

The team can proudly claim to have published more than 15 research papers in international conferences for last 7 consecutive years.

In Swayam, the technique of passive magnetic attitude control system (PMACS) is implemented for the first time on an Indian satellite.

[7] The uniqueness of the technique is that it controls the orientation of the satellite without any power consumption with reasonable accuracy for communication.

It is the scientific mission of the satellite to prove that PMACS is a robust and cost-effective solution for attitude control.

From the simulation results it has been observed that, the stabilization of the satellite to the prescribed orientation, i.e. antenna along Earth's magnetic field, takes around 15 to 20 days.

Over the course of the mission, OC collects crucial data about the health of the various systems within the satellite and stores it in a non-volatile memory, only to be sent to the ground station on request.

The major role of OC relies in handling the set of commands received from the ground stations through the communication system.

Load protection circuits are designed for triple redundancy and work in coordination with the onboard computer and terminal node controller.

The structure subsystem is responsible for providing a robust body for the satellite which can house all the components and protect them from the harsh conditions of space.

Thermal management and control: Temperature of the satellite has to be maintained within a particular range in order to ensure proper functioning.
