COMPASS-1 – first picture

At 1000 UTC we made our first picture of the earth – and we made our first experiences… :-)

A raw image consist of 640 x 480 pixel. Every packet frame (1k2 AFSK) transmit 128 pixel, so we need 5 packets for 1 row. In total we have to transmit 2400 packets to get a full image.
In a good pass a well equipped station can receive about 300 packets. That’s the problem.

In our case we (Thanks Rob, PE1ITR) received only the top and the bottom of the picture. The main part was transmitted over Africa :-(

The second issue was – COMPASS pointed not to earth. So maybe we have the sun on the left side and the dark space on the right. The next task is to bring COMPASS into the ADCS CONTROL Mode.
