WOD uppdaterat

Stacy W4SM meddelar att det har skett en liten ndring av hur Whole Orbit Data (WOD) presenteras:

The K/L/M/N blocks may be used as text messages or as WOD blocks. At the moment K/L are used for WOD s and M/N are for text. This limits our ability to collect more than two WOD s without giving up the text messages. The WOD software can handle up to 4 WOD blocks simultaneously.

Accordingly, the flight software has been modified slightly to store two additional WOD blocks in separate memory which is not normally placed in the telemetry stream. When a command station sends the appropriate command, these two extra WOD s are sent one time only as M/N WOD blocks.

Therefore, occasionally you will see WOD-type M/N blocks in the telemetry stream when AO-40 is being commanded.

SaudiSat 1-A öppen för trafik

Nu r SaudiSat (SO-41) ppen fr amatrradio-trafik. Fljande kommer frn ANS:

BID: $ANS-098.01

AMSAT-NA News Service (ANS) has received word via AMSAT-NA President Robin Haighton, VE3FRH, that SaudiSat 1A is now open for Amateur Radio communications.

In a letter to VE3FRH, Turki Al-Saud announced the following:

Please announce the availability of SaudiSat 1-A (SO-41) to AMSAT members and to follow Amateur Radio operators in your region. Saudi OSCAR-41 has been configured for operation in the amateur service. The spacecraft will automatically enable its UHF transmitter over Saudi Arabia and the United States for approximately 20-minutes each pass.

The spacecraft is operating in Mode-J, centered on a VHF uplink and UHF downlink of 145.850/436.775 MHz, currently configured as an analog FM voice repeater. The spacecraft will operate in this mode intermittently, as power and spacecraft experiments permit.

SO-41 s downlink RF power is 1-watt over both regions with left-hand circular polarization. The uplink antenna (located on top of the spacecraft) is linear in polarization.

SaudiSat 1-B is not available at this time as experiments and software development continues with 1-B.

[ANS thanks Turki Al-Saud and AMSAT-NA President Robin Haighton, VE3FRH for this information]

Och den r ven krd frn Europa:

Heard SO-41 11-apr-2002 from Eindhoven Holland at 13:35 UTC last part from this pass OH5LK Jussi calling cq on SO-41 I was onable to get in with 50 watt on the groundplane TMV-7E downlink porto ft-470 with double quad Handheld signal little better then AO-27.
