Low cost S Band communication system design for nano satellites
Nano satellite structures have limited communication ability due to limited power and size. Most of satellite includes sensors, for instance camera, also image transfer requires more data transfer speed. In this project, 2.4 GHz (S Band) communication system is designed for LEO satellites (700-900 k...

Zusammenfassung: | Nano satellite structures have limited communication ability due to limited power and size. Most of satellite includes sensors, for instance camera, also image transfer requires more data transfer speed. In this project, 2.4 GHz (S Band) communication system is designed for LEO satellites (700-900 km). System includes system-on-chip transmitter device, preamplifier, band pass filter, power amplifier and microstrip antenna array. Microstrip antenna array and RF circuit is designed on FR4. Microstrip array size is 92×84mm 2 and RF circuit size is 38×53mm 2 . Output power of the system is 35dBm for 2.4kbaud data rate, but it can be increased to power capability of the satellite for more data rate. |
