Outline EagleSat-1 communications Reason for improvement Transceiver improvement Antenna improvements Additional improvements EagleSat-2 communications Ground station improvements Results

EagleSat-1 Communications 437.645 MHz 0.5 W transmit power 9600 baud AX.25 Monopole .87 dBi gain

Reason for Improvement Expected 30 Mb of data per pass Each pass approximately 7 minutes Needs more reliability and robustness

Transceiver Improvement Endurosat UHF transceiver 1 W transmit power Specified 100 kbps over air data rate Cost $7000

Antenna Improvements Dual antenna system Directional antenna for data downlink Monopole for backup communications

Additional Improvements A method to switch antenna to prevent interference Using an GAAS MMIC SPDT switch designed for RF signals A method to assist with antenna pointing Using the AD8307 Logarithmic Amplifier

EagleSat-2 Communications UHF frequencies 1 W transmit power Max 100 kbps using AX.25 Monopole antenna with .87 dBi gain Directional antenna with approximately 6 dBi gain

Ground Station Improvements 4.5m mesh dish antenna Wide bandwidth transceiver

Results Preliminary switching tests are promising Signal strength output voltage changes with received power Eb/No, S/N have 17.1dB at horizon
