Successful Launch of swayam!

The success of Satellite team is truly an amazing story of how team work and synchronization can be best nurtured at COEP.
 
The project was started in year 2008. Since then every year around 40-45 students from across the disciplines are working on making a nano satellite of size 10*10*11, weighing 990gm. Each passing batch trains the newly inducted students with the help of our  faculty members. Valuable guidance and support given by the experts from ISRO has played a vital role in executing the entire project and we are thankful for the same. 
We are thankful to all the students who were currently working on the projects and who have graduated from the college for all their hard work and endeavors which has bought glory to the institute and has made us feel proud of our students. We also wish to extend our sincere thanks to our faculty members Dr. Mrs. Manisha Khaladkar, faculty advisor, Dr. S. P. Mohani, Dr. S. P. Mahajan, Dr. A. M. Sapkal, Dr. D. W. Pande and all other who for their valuable and time to time guidance given to these students and to the former and current HoDs of the Dept. of Electrical Engineering, Metallurgy & M. S, Production Engineering & Industrial Mgt. for providing infrastructural assistance to the students for setting up their workstation. Last but not the least we thank our BOG members and Dr. Anil Sahasrabudhe, Chairman, AICTE and Former Director, COEP who have supported the entire team by all means from the start of the project in late 2008 upto the successful launch of the satellite held today.

On behalf of COEP, we once again congratulate the entire Satellite team for this remarkable achievement and wish them all the best for all their future endeavors.
 

                                                                            COEP student satellite - SWAYAM

Technical specifications

Size: 1U standard = 100 mm x 100mm x 113.5 mm

Mass: 990 grams (Picosatellite)

 

Mission objectives

  1. Technological demonstration of passive attitude control system. One magnet for orienting satellite in earth magnetic field direction and two pairs of hysteresis rods for damping velocities in other two axes are used.
  2. Point to point messaging services to HAM community.
  3. UHF (Ultra high frequency) channel performance evaluation.

Orbit: Polar sun-synchronous Low Earth Orbit (500 km – 550 km above earth’s surface)

Launch:To be launched by ISRO’s polar satellite launch vehicle C-34 (PSLV C-34) on 22nd June at 9:25 am IST from SHAR, Sriharikota.

Mission Life: 1 year

Subsystems of Swayam

  1. Attitude Control Subsystem – Responsible for detumbling/stabilisation of satellite and to point the antenna towards the earth. Magnet and hysteresis rods used.
  2. Power system – Solar energy (solar panels on all 6 faces of the satellite) used to power up all electrical systems and to charge Li-ion battery which will be used to power up in eclipse phase.
  3. Communication system – Half duplex communication system in HAM band frequency at 437.025 MHz. Autonomous analog beacon transmitted by satellite every 90 seconds for crucial parameters.
  4. On board computer – Responsible for sensor interface, data handling, storage and implementing custom network layer protocol.
  5. – Responsible for maintaining temperatures inside the satellite, to sustain vibrations of launch vehicle and holding all the components rigidly , providing surfaces for mounting of Solarcells.

Receiving signal from Swayam

COEP has established functional ground station at the top of  metallurgy department. After launch, antenna deployment will take place after 45 min, then it will take a maximum of  15 days for the satellite to stabilise after which reliable communication link will be established between Swayam and ground station. Analog beacon can be sent and  received by any HAM community person. Hardware and software for digital communication has been distributed to many places in India as well as across globe including Spain, Germany and Russia, those ground stations or laboratories will be able to communicate trough SWAYAM and track SWAYAM.

Team

It is an interdisciplinary project having students from all the departments of engineering. It has undergraduate students from all the years i.e. from first year to forth year. Every year there are around 40-45 students in the team.
