CAMSAT XW-4 (CAS-10) Satellite To Be Deployed December 18th

The CAMSAT XW-4 (CAS-10) satellite was launched into the Chinese Space Station on November 12, 2022 aboard China’s Tianzhou-5 cargo spacecraft, and was launched by the Long March-7 Y6 launch vehicle from the Wenchang Launch Center in Hainan, China. It is currently planned that the XW-4 (CAS-10) satellite will be separated from the Chinese space station and enter operational orbit at 01:30 UTC on December 18, 2022.

Initial post-deployment TLEs :

Tevel Mission to Launch on SpaceX Transporter-3 Mission January 13th

The Tevel mission consisting of 8 satellites developed by the Herzliya Science Center in Israel, each carrying an FM transponder, is expected to launch on January 13 at 15:25 GMT on the SpaceX Falcon-9 Transporter-3 mission. This mission also carries AMSAT-EA’s EASAT-2 and HADES satellites.

Tevel-1, Tevel-2 ….Tevel-8

Beacon transmissions on 436.400 MHz, (9600bps BPSK G3RUH)
FM transponders uplink frequency: 145.970 MHz|
FM transponders downlink frequency: 436.400 MHz

All 8 satellites will have the same frequencies, so as long as the footprints are overlapping, only one FM transponder will be activated. The satellites were built by 8 schools in different parts of Israel.

CAMSAT’s XW-3 (CAS-9) to Launch at 03:11 UTC on December 26th

The CAMSAT XW-3 (CAS-9) amateur radio satellite will be launched at UTC 03:11:31 on 2021-12-26, and will be deployed at 98.858° east longitude and 28.413° north latitude at UTC 03:35:58, 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.

Preliminary TLEs are:

1 99999U          21360.14997609  .00000032  00000-0  10363-4 0 00007

Launch Window for AMSAT’s RadFxSat-2 / Fox-1E Opens December 19th

Virgin Orbit has announced that the launch window for their LauncherOne Launch Demo 2 mission opens on December 19th. This launch will carry AMSAT’s RadFxSat-2 / Fox-1E to orbit.

RadFxSat-2, like RadFxSat / Fox-1B, now AMSAT-OSCAR 91, is a partnership opportunity between Vanderbilt University and AMSAT and will carry a similar radiation effects experiment, studying new FinFET technology.

RadFxSat-2 is the fifth and final Fox-1 satellite built by AMSAT. The RadFxSat-2 spacecraft bus is built on the Fox-1 series but features a linear transponder “upgrade” to replace the standard FM transponder in Fox-1A through D. In addition, the uplink and downlink bands are reversed from the previous Fox satellites in a Mode V/u (J) configuration using a 2 meter uplink and 70 cm downlink. The downlink features a 1200 bps BPSK telemetry channel to carry the Vanderbilt science data in addition to a 30 kHz wide transponder for amateur radio use. Telemetry and experiment data can be decoded using FoxTelem version 1.09 or later. FoxTelem is available at

Participation in telemetry collection by as many stations in as many parts of the world as possible is essential as AMSAT Engineering looks for successful startup and indications of the general health and function of the satellite as it begins to acclimate to space. AMSAT will send a commemorative 3D printed QSL card to the first station capturing telemetry from RadFxSat-2.


RadFxSat-2 (Fox-1E) – Launch Window Opens December 19th
Uplink LSB 145.860 MHz through 145.890 MHz
Downlink USB 435.760 MHz through 435.790 MHz
Launches on ELaNa XX – Virgin Orbit LauncherOne Launch Demo 2. 1.2kbps BPSK telemetry 435.750 MHz
