QARMAN and Phoenix CubeSat Deployment from ISS

Phoenix logoSarah Rogers KI7OOY reports that following the successful launch of NG-13 on Feb 15, the upcoming CubeSat deployment from the ISS is now scheduled for Wednesday, February 19.

This deployment times and frequencies for the CubeSats being deployed on this date are listed in the table below.

As a member of the Phoenix CubeSat team, it would help us greatly to have as much help as possible with tracking our spacecraft following deployment!

For more information on Phoenix’s transceiver characteristics and how you can decode packets from our spacecraft, please see our operations page:

If you have any questions regarding deployment or tracking Phoenix, please do not hesitate to reach out to me.

QARMAN and Phoenix CubeSat Upcoming Deployment

Phoenix logoSeveral CubeSats are expected to be deployed from the International Space Station into orbit next week, among them are QARMAN and Phoenix.

Amandine Denis ON4EYA of the QARMAN project reports that due to the delays in Cygnus launch, deployments are postponed most likely to early next week, after Cygnus docking. Qarman can’t wait to make the big jump! See

QARMAN will perform experiments on stability during the the orbit phase and measurements of ablation and radiation during re-entry.

Phoenix is a 3U CubeSat developed by Arizona State University to study the effects of Urban Heat Islands through infrared remote sensing. Following deployment, the Phoenix operations team would appreciate as much help as possible with identifying the spacecraft and verifying that it is operational.

Please note that two CubeSats being deployed operate on the same frequency. Both Phoenix and QARMAN share the frequency of 437.35 MHz, and both utilize an AX.25 9600 baud protocol with GMSK modulation. Both CubeSats will also be deployed within 1.5 hours of each other, and will therefore be close to each other in orbit. Please be mindful of this situation, and if you have any doubt about the CubeSat that you are receiving, please get in touch with Sarah Rogers KI7OOY, Project Manager, Phoenix CubeSat, sroger13 [at} with any questions or concerns.

HuskySat-1 with 145/435 transponder to deploy from Cygnus



ARRL reports University of Washington’s HuskySat-1 3U CubeSat, launched November 2, 2019, is set to deploy January 31 after the vehicle that carried it to the International Space Station undocks.

Update January 31, 2020: HuskySat-1 is expected to be deployed by Cygnus at 22:30 GMT on Jan 31, the 435.800 MHz beacon should be activated at 23:05 GMT.

ARRL say:

HuskySat-1 has remained stowed aboard a Northrop Grumman Cygnus supply vehicle. Within 24 hours after Cygnus’ departure from the ISS, HuskySat-1 and SwampSat 2 will be deployed into orbit. After deployment, HuskySat-1’s 1,200 bps BPSK beacon on 435.800 MHz should be active and decodable with the latest release of AMSAT’s FoxTelem software. HuskySat-1 is expected to carry out its primary mission before being turned over to AMSAT for amateur radio operation.

HuskySat-1 features a 30 kHz wide V/U linear transponder for SSB and CW. The uplink passband will be 145.910 – 145.940 MHz LSB/CW. The downlink passband will be 435.840 – 435.810 MHz USB/CW (inverting). Telemetry will be transmitted on 435.800 MHz, 1k2 bps BPSK with an experimental downlink at 24.049 GHz.

Qarman beacon telemetry information released



QARMAN, a nano-satellite designed and built at VKI, was launched to the International Space Station on December 5, 2019. Deployed is expected to take place in the week of February 12, 2020.

QARMAN (Qubesat for Aerothermodynamic Research and Measurements on AblatioN) is the world’s first CubeSat designed to survive atmospheric re-entry. Work on it started in 2013 at the von Karman Institute for Fluid Dynamics (VKI).

The aim of the QARMAN mission is to demonstrate the usability of a CubeSat platform as an atmospheric entry vehicle. Spacecraft descending towards a planet with an atmosphere experience very harsh environment including extreme temperatures (several thousand degrees).

Information about Qarman’s 437.350 MHz 9600 bps GMSK AX.25 beacon has now been released by the team.

Decoding OPS-SAT's beacon

Decoding OPS-SAT’s beacon

ESA is challenging anyone with amateur radio equipment to catch the first signals from OPS-SAT, ESA’s brand new space software laboratory.

On December 17, the 3U CubeSat OPS-SAT will be launched into low-Earth orbit on a Soyuz rocket from Kourou in South America, together with ESA’s Cheops exoplanet-tracker.

Lift-off is scheduled for 08:54:20 GMT on Tuesday, December 17. Deployment will begin 15044.6 seconds later (T+15044.6 seconds), expected to be at 13:05:04 GMT.

15 minutes after satellite deployment, when the UHF antenna and solar array deployment have been confirmed, OPS-SAT will begin transmitting 9600 bps GMSK on 437.200 MHz. The first two passes over Europe are expected on the same evening.

The OPS-SAT flight control team has developed open source software which allows anyone to receive the 437.200 MHz beacon of OPS-SAT and decode it.
