  1. BHARATI VIDYAPEETH COLLEGE OF ENGINEERINGRITESH ANANDSWAPNIL MISHRAPROJECT GUIDE : Prof. A. V. SUTAR

  2. INTRODUCTION

  3. BVCOE GROUND STYATION TEAM WITH H.O.D AND PRINCIPAL

  4. GROUND STATION TEAM WITH IITB “PRATHAM” TEAM MEMBERS

  5. INFORMATION ABOUT PRATHAM • DIMENSION 260mm X 260mm X260mm • WEIGHT 10KG • 10:30 POLAR SUN SYNCHRONIZED ORBIT • 3 MONOPOLE ANTENNA • KILL SWITCH • AUTONOMOUS

  6. EXPLODED VIEW OF PRATHAM

  7. OBJECTIVE • Low cost Ground Station • TEC (Total Electron Count)

  8. TEC :PLOT OF ELECTRON DENSITY WITH RESPECT TO LATTITUDE AND LONGITUDE IS CALLED TOTAL ELECTRON COUNT MAP(TEC).

  9. FARRADAY’S LAW ∆ɸ=4.87*10-4*f-2 ʃ ΝΒcosӨdl ∆ɸ = CHANGE IN ANGEL OF POLARIZATION PLANE Ν = ELECTRON DENSITY B = MAGNETIC FIELD OF EARTH Ө = ANGLE BETWEEN THE MAGNETIC FIELD AND THE DIRECTION OF PROPAGATION OF THE RADIO WAVE. f = FREQUENCY

  10. Roll of Our Ground Station(contd.)

  11. OUR APPROACH ANTENNA Two crossed yagi antenna Centre frequency 437 MHz and 145 MHz Receiving Section LNA Polarization Circuit Analog to Digital Converter PC LNA LNA Polarization Circuit LNA Tracking Section ROOF UNIT LAB UNIT Control Circuit(PIC µC) BURNING UNIT PC(RTT) MOUNT

  12. Fully fabricated antenna at centre frequency 437Mhz Fabricated Antenna Fully fabricated antenna at 145 MHz frequency.

  13. TRACKING SYSTEMS Rotator ARS

  14. TRACKING SECTION ROOF UNIT LAB UNIT BURNING UNIT PC(RTT) Control Circuit(PIC µC) MOUNT

  15. ALGORITHM FOR STEPPER MOTOR 1 START ACCESS VARIABLE SA=STEP ANGLE AOSS=ACQUISITION OF SIGNAL START AOSE= ACQUISITION OF SIGNAL END NO TD= TOTAL DURATION DELAY YES ANGLE PER SECOND APS=(AOSE-AOSS)/TD NUMBER OF STEPS PER SECOND NSS=APS/SA TOTAL STEPS TS= NSS x TD DELAY= TD/TS EXECUTE DELAY TS=TS-1 CHECK IF TS=0 RESET END

  16. ALGORITHM FOR STEPPER MOTOR 2 START ME= max. elevation AE= ME-0.05ME EXECUTION END

  17. Real Time Satellite Tracking Software

  18. Real Time Satellite Tracking Software

  19. CONCLUSION • TEC MAP OF INDIA. • Application of Theory. • Commercial Application of TEC. • Social Goal

  20. THANK YOU
