Swayam Satellite

Swayam Satellite:

     Swayam is a small picosatellite ( otherwise called Cubesat ) developed by the undergraduate students of Pune College of Engineering. The Cubesat has 1-U flight model weighing 990 grams which was successfully assembled by the students under the guidance of Indian Space Research Organisation (ISRO) in January 2015.

Design:

     Structural design, electronic and control systems as well as the manufacturing of the satellite was fully carried out by the Indian Students. 200 students took 8 years to complete the Cubesat project.

Launch:

     The satellite was successfully launched by Indian Space Research Organisation (ISRO) on 22nd June 2016 along with the Indian Satellite Cartosat-2C. These satellites were carried by indigenous Polar Satellite Launch Vehicle (PSLV-C34) from Sriharikotta, second launch pad at Satish Dhawan Space Center, India. The satellite was placed at an attitude of 515 kilometer in low earth orbit around the Earth.

Objectives:

     To provide point to point messaging between HAM Community.

Satellite Components: 

   The satellite consists of

• Amplifiers - to amplify the received signals
• A Dipole Antenna - for communication systems
• Texas Transceiver - Ref.No: CC1120 RF Travsceiver
• Microchip - PIC micro-controller is interfaced with Transceiver

Technical Details:

• Uplink and Downlink bands are 435 MHz and 145 MHz
• Micro-controller --- AT91SAM7 with 512 MB of RAM
• Lithium-ion Batteries and DC to DC circuits were used to regulate power supplies
• Thermal Management and Control - Thermal control of satellite was managed by Insulating tapes, white paints, black tape and Optical Solar Reflector.

Achievements:

     The team published more than 15 research papers in International Conferences  for last Seven Years.
