Technical Report on Reverse Engineering of High Power Supply

Reference Document for the Lab Report in the course Electronics in Space

(Erasmus Mundus Space Master, Swedish Institute of Space Physics)

This report presents the practical and theoretical verification of the results obtained by performing an experiment on Reverse Engineering of a High Voltage Power Supply. The lab consists of two main parts: block by block and overall system analyzing; system testing. The idea of analyzing obtained test results is to compare practical results (waive forms entered by the oscilloscope) with theoretical expectations ensued from circuit analyzing.

Technical Report on CMOS Array as part of the Electronics in Space Course

Reference document for the course Electronics in Space

(Erasmus Mundus Space Master, Swedish Institute of Space Physics)

This report presents the practical and theoretical verification of the results obtained by performing an experiment on the Hamamatsu, S2996 CMOS array. The practical part of the lab was to illuminate the array with different frequencies and exposure periods, and also to test the Schmitt Trigger circuit which was built by us. In the end we detect the faults that were present in the CMOS array.
Since our team consists from two members only we decided to write this report together. Except some typing, drawing and scanning routine which was distributed equally among members, the whole process of writing this report was accomplished by Sanjay and Vladimir in hand and glove.

Ground Station Design for a Nano Satellite

Co-authored with Vikash Kumar, Sindhu Mannava, Vishal Shekhar

This paper would address the development of the ground station from design phase to testing phase using the commercially available of the self components (COTS) with the limited resources available. The ground station of SRMSAT uses the amateur frequency band for sending Tele-Commands from the ground station and to receive payload and housekeeping data through the beacon. The novelty lies in the in-house design and development of the transmitter, receiver system including the antenna’s (Quad Stacked Dual Polarized Yagi-Uda antenna) for ground station. The Ground station of the satellite is operated in VHF & UHF band, with uplink at 145.8MHz and downlink at 434.5MHz. It consists of transmitter, receiver and beacon signal receiver. Beacon signal will be transmitting satellite id and health parameters of the satellite. The Design would also address the in house development of the Tele-commanding software and Graphical user interface for various data interpretations.
