Title :5.8GHz帯用ドップラーシフト補正システム
Authors :田中 健太

Issue Date :Feb-2014
Abstract :We have developed a 10cm cubesat, FITSAT-1, which was deployed from ISS on 5th October 2012 and decayed on 4th July 2013. The main mission of the FITSAT-1 is to demonstrate a high speed transmitter module developed by our group. It could send VGA (640x480pix)resolution jpeg image data at 115.2kbps FSK in 2 to 6 seconds using 5.84 GHz ham band. The frequency shift by Doppler is almost plus or minus 150 kHz at 5.84 GHz. It is not easy to adjust the receiving frequency by manually. So we developed a software mechanism of automatic tuning system which compensates Doppler shift.
