CAMSAT XW-3 (CAS-9) To Be Launched Today

The CAMSAT XW-3 (CAS-9) amateur radio satellite is scheduled to be launched today, 2021-12-26, at 03:11:31 UTC, and will be deployed at 98.858°E and 28.413°S at UTC 03:35:58, a location close to Western Australia.

Radio amateurs will receive CW beacon and GMSK telemetry signals approximately 38 seconds after the satellite is separated from the launch vehicle, and then the linear transponder will be put into use after approximately 49 seconds.

CAMSAT is looking for the CW beacon and telemetry monitoring from Western Australia, South America and North America during the first orbit of the satellite.

A preliminary Two-Line Orbital Element set has been released. However, any launch delay will affect this prediction radically, and radar-confirmed TLEs will probably not be available for several days:

CW telemetry beacon:
*Frequency: 435.575MHz
*RF power: 20dBm
*CW rate: 22wpm

GMSK telemetry:
*Frequency: 435.725MHz
*RF power: 23dBm
*Data rate: 4800bps

V/U mode linear transponder:
*Uplink frequency: 145.870MHz
*Downlink frequency: 435.180MHz

ARISS SSTV Event Scheduled for Dec 26

An ARISS Slow Scan TV (SSTV) event is scheduled from the International Space Station (ISS). The event is slated to begin on December 26 at 18:25 UTC for setup and operation and continue until December 31 ending at 17:05 UTC. Dates and times subject to change due to ISS operational adjustments.

Images will be downlinked at 145.8 MHz +/- 3 KHz for Doppler shift and the expected SSTV mode of operation is PD 120.

The main theme will be for this event will be lunar exploration. Radio enthusiasts participating in the event can post and view images on the ARISS SSTV Gallery at .

After your image is posted at the gallery, you can acquire a special award by linking to and follow directions for submitting a digital copy of your received image.

Bob Davis, KF4KSS, AMSAT Engineer, SK

Robert “Bob” Davis, 49, passed away on December 10, 2021 at his home in Pocomoke City, Maryland. Bob became part of the AMSAT Engineering team in 1996 after graduating from the University of Central Florida with a degree in mechanical engineering. He was instrumental in the revision to the satellite structure of the Phase 3D spacecraft, adding his expertise to the mounting system and solar panel deployment system.

Bob was involved with every AMSAT & ARISS project since 1996, including Eagle, Suitsat, ARISSAT and the FOX series of satellites. He helped design, build, test and certify the FOX and next generation and was working on the GOLF satellites. More on Bob’s personal life and family can be found at

The family has requested that, in lieu of flowers, a donation be made to AMSAT at

AO-73 Mode Change Made

FUNcube-1 (AO-73) mode has been changed. It will be in telemetry mode in sunlight and silent during eclipse. This will allow the team to gather valuable telemetry, including energy consumption and battery health in current illumination conditions. This is not an error!

We are grateful for the continued uploading of telemetry data to the Amsat-UK data warehouse, and the continued support of everyone in gathering it!

[ANS thanks Wouter Weggelaar, PA3WEG, FUNcube Operations Team, for the above information]


AMSAT’s GOLF Program is about getting back to higher orbits, and it all
begins with GOLF-TEE – a technology demonstrator for deployable solar
panels, propulsion, and attitude control, now manifested for launch on
NASA’s ELaNa 46 mission. Come along for the ride. The journey will be
worth it!


Change Of Operation Schedule of FO-99 / NEXUS

The NEXUS operation team has announced that the operation schedule for FO-99 / NEXUS has been changed. Recently, based on the situation where the operation of other general-purpose transponder satellites has become unstable one after another, we will temporarily operate the FO-99 / NEXUS transponder. The following 3 passes (1st pass on Sunday evening) are usually his schedule for digital talker operation, but we will change the schedule and temporarily operate transponders, so we will inform you.

New release of AMSAT Status for Android

Loren Lang, K7IW, has developed an Android app for publishing status updates to the AMSAT website satellite status page ( and pulling down previous reports through the site’s published API. Since last year, Loren has fixed a few bugs on different Android platforms and also added a Google Maps view which shows the location of satellite reports on a map. It will also save preferred satellites and has a “find me” button for filling in the grid square automatically. The app is on the Android Play Store in a closed beta.

To join in on the testing, open this link:

And the app can be opened on your phone with this:

Or search for AMSAT Status. Please provide any feedback or feature requests you want on the app.

Satellite Shorts From All Over

+ W2JV will be conducting “The Art of Working thru the Amateur Satellites” as part of the online “Ham Radio University” event on January 8th, 2022. Registration is now open at (ANS thanks Peter Portanova, W2JV, for the above information)

+ A Soyuz spacecraft carrying a Russian cosmonaut and two Japanese private astronauts returned to Earth late Dec. 19. After 11 days on the station, the Soyuz returned to Earth Roscosmos cosmonaut Alexander Misurkin along with Japanese private astronauts Yusaku “MZ” Maezawa and Yozo Hirano. The flight brokered by American space tourism company Space Adventures. (ANS thanks Space News for the above information)

+ The liftoff of a SpaceX cargo ship on the way to the International Space Station early Tuesday was the 31st and final orbital launch from Florida’s Space Coast in 2021, setting a new record for the most space missions to depart from the spaceport in a calendar year. It was also the 31st Falcon 9 launch of the year overall for SpaceX, including 28 from Florida and three launches from Vandenberg Space Force Base in California, setting a company record. (ANS thanks Spaceflight Now for the above information)

+ Two new Astro Pi units launched were launched into space on December 21, 2021. The new Astro Pi units each consist of a Raspberry Pi computer with a Raspberry Pi High Quality Camera and a host of sensors, all housed inside a special space-ready case that makes the hardware suitable for the International Space Station (ISS). The launch was the culmination of three years of work Raspberry Pi has done for the European Space Agency to get the new Astro Pi units ready to become part of the European Astro Pi Challenge. The complete story can be found at: (ANS thanks the Raspberry Pi Foundation for the above information.)

+ Derek, OK9SGC, has recently uploaded a very comprehensive beginners guide to receiving HRPT weather satellite images. The guide covers almost everything from purchasing and building the hardware, to finding and tracking the satellites, to setting up the software and decoding images. HRPT reception can be a little daunting as it requires a good L-Band dish setup which involves choosing and building a feed, and importantly, a way to track the satellite with the dish as it moves across the sky. Find this story and a link to the guide at: (ANS thanks for the above information)

+ The WSJT-X development group has announced the release of WSJT-X 2.5.3. Those using FT-4 or other digital modes on linear satellites are reminded that most such operations occur at the low end of downlink passbands, and that transmitter power should be kept to a bare minimum to avoid damage to the satellites. (ANS thanks ARRL and AMSAT for the above information).

+ The James Webb Space Telescope, the “most powerful and complex space telescope ever built,” was successfully launched on Christmas Day after having been delayed a first time due to a communication issue between the observatory and the launch vehicle and then again for bad weather. JWST’s deployment process involves 50 deployment actions and 344 single-points of failure. As one NASA official said, “Those who are not worried or even terrified about this are not understanding what we are trying to do.” (ANS thanks The Orbital Index for the above information)

+ A Merry Christmas to all our readers from the AMSAT News Service staff!
