Lite status om Oscar 40 frn ANS kommer hr (OBS! nytt schema ocks!):
AO-40 continues to move in ALON, keeping ahead of the sun. As of 31 Oct 2003, AO-40 s attitude was ALON/ALAT ~ 30 / 0. ALON will slowly be advancing to 45 deg.
The passband schedule has been modified slightly and the K-band window has been discontinued.
Stacey Mills, W4SM, provided the following update regarding AO-40 s telemetry beacon. Stacey says, FEC is turned on as for as many orbits as possible, working around the need for pictures and other command functions.
FEC mode requires loading the IHU-2 each orbit and this is not always possible; however most orbits have FEC active. The FEC routine has been modified to allow the option of cycling between normal mode telemetry including message blocks and event blocks, and FEC mode telemetry (A-blocks only). With this option, the normal mode is currently active from 0 to 16 minutes of the hour, and the FEC mode is active for the remainder of the hour. This allows time for users to read the message blocks and for event blocks to be collected. During transition between these two modes, up to 1 minute of beacon idling (hex50) may be heard before the new mode starts.
The AO-40 team would like your telemetry files! Please zip compress your daily telemetry files and e-mail to: ao40-archive@amsat.org
