[amsat-bb] AO-40 Update 23Oct02

[Graham Ratcliff <gratclif@xxxxxxxxxxxx>]

As planned AO-40 has been allowed to drift to ALON 330 and ALAT +30, this 
target attitude was reached on the 23Oct02.

A command has been uploaded to AO-40 on 23Oct02 at 1034utc to initiate 5 
perigees of magnetorquing to stabilise the ALON drift due to the mystery 
effect at about 300 to 340 and to reduce the ALAT from +30 to +15 degrees.

At this stage no changes have been made to the operating schedule. However, 
over the next few days as the ALAT decreases towards +15 degrees signals 
should improve as squint angles improve.

When the ALAT reaches +15 degrees the YACE camera will once again be 
activated to take pictures of the earth to accurately determine/monitor the 
attitude of AO-40.

The message blocks on AO-40's telemetry will be updated after the YACE 
camera attitude determination has been completed.
