Status 2:a november

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

Ballongprojekt från AMSAT-CT

AMSAT-SM fick fljande info frn AMSAT-CT angende ett ballongprojekt de just gjort. Dom har tappat bort ballongen och behver hjlp:

Greetings to all,

as part of the group of AMSAT-CT and AMRAD PT, please alow
me to introduce us to the AMSAT organizations that don t
know us yet.

Please take a wee time to check our webpage (in Portuguese), as it has info on the organization, and also
on the balloon launch.

Balloon launch –
http://www.amrad.pt/lancamento_cinelsat2.php

AMRAD s balloon was lauched last Friday, 24th October,
around 5:30pm GMT. The payload consisted on a Video Camera, ATV 1260MHz, GPS receiver, APRS tracking device transmitting on VHF 145.850MHz. Four balloons pulled it up, and a parachute went together. (first picture shows the setup) It has inside the payload, a plastic wrapped paper with ID, contacts and emails.

The balloon was tracked for more than 10h with the precious help of CT1FAK, and other collegues, using their powerfull receiving stations, equiped with the latest radio technology.

The last received packet from the ballon, at CT1FAK s station, has the timestamp of +-3:30am GMT 25th October. We lost contact with the balloon after that. We received logs from our friends in the NorthWest Spain, Galiza, with timestamps of 7:49am Zulu same day. They had the last contact with the running balloon.

The balloon climbed up to 27xxx feet only. Bad weather and
heavy clouds didn t allow it any further up. According to wind charts, forecasts and local Meteo office, we had East winds that would push the balloon into middle Atalantic Ocean, and later north. Is this correct ?? Theres no way to know this. The balloon is already electrically dead .

Hence our contact to the countries around the Atlantic
Ocean. As the payload is pulled by four balloons, we presume it is still floating around somewhere, if it hadnt burst because of the heavy cloud ceiling, that didn t allow it any further up.

We take the opportunity to ask for help (and some advise),
if by any chance the balloon falls in your country, is
picked up in the ocean by boats/fishermen, or picked at the sea shore.

On behalf of AMRAD s board and associates, we thank you all. For reading, for spreading the news to your associates and collegues, and for, who knows, catching the payload 🙂

Oscar Echo upp mars 2004

Fljande information har kommit om nya satelliten frn AMSAT i USA, Oscar Echo:

AMSAT-North America has announced that launch of the AMSAT OSCAR-E Amateur Radio microsat–the Echo Project — is scheduled to launch March 31, 2004. Earlier plans had called for a May 2004 launch. Echo Project Team member Richard Hambly, W2GPS, reported at AMSAT-NA s Annual Meeting and Space Symposium October 18-19 in Toronto, Canada, that the Echo project has made significant progress in recent months.

A Russian Dnepr LV rocket–a converted SS-18 intercontinental ballistic missile–will carry the approximately 10-inch-square satellite into a low-Earth orbit from the Baikonur Cosmodrome in Kazakhstan.

Echo Project Team member Richard Hambly, W2GPS, reported that the project team powered up the Echo flight hardware in late summer in a flat-sat configuration at SpaceQuest. Data communications, command and control, and attitude control subsystems were tested, in addition to the radio equipment, power systems and cabling.

The satellite will incorporate two UHF transmitters, each running from 1 to 8 W and capable of simultaneous operation, four VHF receivers and a multiband, multimode receiver capable of operation on the 10 meter, 2 meter, 70 cm and 23 cm bands. Echo will feature V/U, L/S and HF/U operational configurations, with V/S, L/U and HF/S also possible. FM voice and various digital modes–including PSK31 on a 10-meter SSB uplink–also will be available.

[ANS thanks Dave Hassler, K7CCC, for the above information.]
