----------------------------------
UoSAT-F Intended orbit: height about 780km, incl 98 deg.
sending AX.25 data at 9600 bps.
Uplink is 2m and downlink is 70cm
UO-22 carries a camera with a wide-angle lens (110 deg) giving a broad field
of view. Images will represent 1600 x 1800 km;
The image will be 578 x 576 pixels, giving about 2 km ground resolution. A
pixel is 8 bits, giving a black and white image with 256 grey levels. UO-22
will broadcast images using the PACSAT Protocol.
UoSAT-F FREQUENCY PLAN
Downlink
435.120 MHz
9600 bps FSK
1200 bps AFSK (backup)
5 W or 2 W
Uplink
145.900 [and 145.975 MHz]
9600 bps FSK

NOTE: This channel will be used by groundstations transmitting
"hole lists" for the PACSAT Broadcast Protocol. There should be little
interference with the Microsat uplink on the same frequency.
