AO-40 Update

Due to the worsening solar angle we have begun off-pointing ALON at the rate of about 1 deg/day. ALON/ALAT was ~ 18 / 0 on 11/12 Oct 2003. ALON will be slowly advancing to 45. Watch the telemetry beacon's N-block for updates.

Due to the changing attitude, the schedule has been adjusted with transponder operations moving later in the orbit. The new schedule is shown below.

YACER Software Update

Those interested in following the ALAT and ALON of AO-40 from the shack: Paul, KB5MU, has just posted the latest version of YACER on the AMSAT.org web site. "YACER", Yet Another Camera Experiment - Revisited, is a suite of the programs that the Ground Controllers use to determine the current ALAT and ALON of our spacecraft by using pictures taken with the YACE camera. While not for the faint of heart, it is truly a fun project, especially at this time of year when there is plenty of spacecraft re-orientation.

The latest version, V1.05, is the same as prior versions with the exception of a bug-fix to the program ConvKeps. If you presently have YACER you can go to the AMSAT site and download ONLY the new ConvKeps V1.5e program. Present users should probably just take the new program, not the complete suite, since the suite is an auto executable file that will re-establish the complete file structure. You will risk overwriting files that you have created earlier.

The same package and stand alone program, in German documentation, will soon be available on AMSAT-DL.

HAMSAT Launch Delayed

HAMSAT also known as VUSat, which was to be a co-passenger of a remote sensing satellite onboard a Polar Satellite Launch Vehicle (PSLV) from Sriharikota launch range later this month, will not make the trip.

An official release from ISRO said that the Hamsat was to be launched as an auxiliary payload using the launch capacity of PSLV. Unfortunately, during the thermovacuum test of Hamsat, deviations in the performance of the ham payload were observed.

After the required corrections have been made, Hamsat will be accommodated on one of the subsequent flights of PSLV.

Updated information is available from the web sites www.amsatindia.org and www.amsat-india.org
