New Chinese Amateur Satellites Expected to Launch in September

Two new Chinese amateur radio satellites are now expected to launch on September 15, 2020. The first of these satellites, CAS-7A, is a 27 kg microsat (750 mm x 650 mm x 260 mm) with three-axis stabilization and several transponders. The transponders include a 15m to 10m linear transponder (H/t), a 15m to 70cm linear transponder (H/u), and a 2m to 70cm linear transponder(V/u). The satellite also includes a 2m to 70cm (V/u) FM transponder. Several beacons and data downlinks are also featured, CW beacons on 10m and 70cm, 4.8k or 9.6k GMSK telemetry on 70cm, and a 1 Mbps GMSK image data downlink on 3cm for the on board camera. IARU coordinated frequencies for the uplinks and downlinks are listed below.

This launch is also expected to carry CAS-7C, a 2U CubeSat with a V/u linear transponder and a CW beacon. Frequencies for CAS-7C have not been coordinated by the IARU at the time of this writing. CAS-7C will also deploy a 1 mm diameter 1080 meter long carbon fiber rope.

CAS-7A and CAS-7C will launch from Jiuquan Satellite Launch Center into a 500 km sun-synchronous orbit with an inclination of 98 degrees.

Visual Observations of RS-44 Underway

Visual observations of the payload and attached Briz-KM rocket body made whilst the object has been flying over the UK at night, indicated a rotation period of 19 seconds. Optically with binoculars, it appeared between magnitude +5 to invisible in hazy moonlit skies, on near zenithal transits. No flashes nor glints were observed, which could indicate the stack is in a slow roll along the longitudinal axis, rather than a tumbling motion.

On a radio aspect, it would appear the beacon signals are stronger as the payload approaches, declining thereafter upon passing TCA. Assuming RS-44 is mounted to the front and that some aerials have deployed, then this would account for the phenomenon, as receding away from the station would have the aerials blocked by the Briz rocket body – however, I have not seen any information released as to the physical condition of RS-44. It would be useful for the transmitters to remain on, to monitor over the long term if the nutation rate slows over time. The CW beacon was timed at 20 seconds between transmission, which fits with the optical work, but this may well just be coincidental as to how the beacon is programmed.

Later radio monitoring indicates the beacon repetition is 15-16 seconds on the callsign being transmitted. Whether this ties in with hopefully future optical work to see if the spin rate has slowed to the same, or we have a differential – we wait and see!

Hack-a-Sat Call for Participation

I’ve put out the call for participation for the Hack-a-Sat competition in the past, and would like to bring you all up to date on the developments and opportunities that have developed since.

The website is here:

Hack-a-Sat is an activity that was scheduled to happen at the in-person DEFCON event.

As of today, yes, it’s true. DEFCON has been cancelled.

Those of you that have volunteered at Ham Radio Village in the past are familiar with the event. For those of you that are not, it’s a long-running hacking and cybersecurity event that has enthusiastically adopted everything RF and amateur radio.

The United States Air Force, in conjunction with the Defense Digital Service, organized this year’s Space Security Challenge, called Hack-A-Sat. This challenge asks hackers from around the world to focus their skills and creativity on solving cybersecurity challenges on space systems. This competition is going to be held! It’s now a virtual event.

Security in the amateur radio sense of the word is fundamentally different from commercial and military applications. We have an advantage here, mainly due to the enormous leverage we have due to our context being completely different from what the Air Force and commercial interests assume. This is, essentially, a diversity advantage.

If you want to participate on an experienced Capture The Flag (CTF) team, then I am here to extend an invitation. Anyone that reads through the rules and can afford to spend some time during the event is invited to apply to join Vaporsec. This is a team that has a majority of information security professionals. There are some satellite industry people, some amateur involvement, and I’d like to make sure that anyone interested in competing from AMSAT gets a chance to join a competitive team.

The benefits to amateur radio are primarily technical, with policy and security a close second. The Air Force has some agendas here in terms of improving satellite security. Exposure to the challenges alone is a an excellent opportunity to learn more about modern satellite technology… and what a significant player in space wants to find out more about. Don’t assume that that the challenges in the competition are going to be “too hard.” What is trivial for one viewpoint is unsolvable for another.

I’ll be writing about the event and what we learned when it is over, so this sort of knowledge will not be secret. However, there is no replacement for participation, and you could very well have the practical knowledge, gained from operating real satellites, that wins the competition. As you can see from the website, there is some real money involved and opportunities for technical writing.

Let me know at [email protected] if you would like to talk more about joining a CTF team for this really neat and unique event. Know someone that you think should participate? Please forward to them.

NASA TV To Air Cygnus Departure From Space Station

Nearly three months after delivering several tons of supplies and scientific experiments to the International Space Station, Northrup Grumman’s unpiloted Cygnus cargo craft is scheduled to depart the International Space Station on Monday, May 11.

Live coverage of the spacecraft’s release will air on NASA Television and the agency’s website beginning at 11:45 a.m. EDT, with release scheduled for noon.

Dubbed the “SS Robert H. Lawrence,” Cygnus arrived at the station on February 18. Within 24 hours of its release, Cygnus will begin its secondary mission, hosting the Spacecraft Fire Safety Experiment – IV (Saffire-IV), which provides an environment to safely study fire in microgravity. It also will deploy a series of payloads. Northrop Grumman flight controllers in Dulles, Virginia, will initiate Cygnus’ deorbit to burn up in Earth’s atmosphere Monday, May 25.

More information on Cygnus’ mission and the International Space Station can be found at:

Satellite Distance Records Set

The DX record on RS-44 has fallen once again! EA4CYQ reports a QSO with UA0STM at 19:00 UTC on 06-May-2020. The distance between the two stations is 7,894 km.

Another claimed DX record was also claimed on May 6. This time it was on PO-101 (Diwata2PH). EA4SG reports working R9LR at 23:03 UTC. The distance between the two stations is 5,128 km.

Distance records for all satellites are maintained at:

Please email n8hm [at] if you wish to claim a new record, longer distance QSO not yet documented, or records for any other satellite/transponder not yet listed. Please note that if a satellite carries multiple transponders or supports multiple frequency bands, records on each transponder/band may be claimed, such as Mode A and B on AO-7 or Mode U/S, L/S, U/K, etc, on AO-40. This includes the ISS and records may be claimed for the packet digipeater and crossband repeater, but does not include different operating modes on the same transponder (such as CW or SSB on AO-7 Mode B).

Upcoming Satellite Operations

Mitch, AD0HJ, has decided to “go check on the tree” in North Dakota. He has also said he will be activating a bunch of grids:

  • 5/20 UTC DN96/97
  • 5/21 UTC DN78/88
  • 5/22 UTC DN76/77
  • 5/23 UTC DN86/87
  • 5/24 UTC EN06/16

Details on his Twitter page, @ad0hj

Ron, AD0DX, and Doug, N6UA, are making another run at the elusive DL88 in Big Bend National Park, Texas. They tried this grid back in March, and due to the mud couldn’t get to the grid, so never ones to quit, off they go again. The tentative date is Sunday May 31, 2020. They will be using the K5Z call sign. More information is available at the K5Z QRZ Page.

Please submit any additions or corrections to ke0pbr (at)

+ NASA will pay a staggering $146 million for each SLS rocket engine, with 4 needed per SLS flight. These Space Shuttle main engines were intended to be reused, but SLS will throw them away. Other things you could buy for $146 million: two basic Atlas V rocket launches, three Falcon 9 launches, or a fully expendable Falcon Heavy launch, with 2/3 the lift capacity at 1/20th the cost.
(ANS thanks The Orbital Index for the above information)

+ A study has found that all 1,078 commercially-launched smallsats in the last five years experienced delays, with a median delay of 128 days. The largest delay categories: 11% of delays were administrative, 13% were ISS manifest changes (for ISS-deployed sats), 20% were due to delays in launch vehicle development, and 40% were due to primary payload delays affecting their rideshares. Full report at

+ A satellite built by Air Force Academy cadets will launch into space May 16 aboard the X-37B, Orbital Test Vehicle sponsored by the Department of the Air Force Rapid Capabilities Office and built by Boeing. This is the first time a satellite built and designed by cadets will catch a ride into space aboard the X-37B. Falcon sat-8 will carry five experimental payloads, and members of the Cadet Space Operations Squadron will operate it. There was no mention of amateur radio connected with this satellite, nor has there been a request for IARU frequency coordination in the amateur radio satellite service, although previous FalconSats have had amateur radio payloads.
(ANS thanks U.S. Air Force Academy for the above information)

+ When a new crew member arrives on the International Space Station, the population of humans living in space changes, of course. But so, too, does the population of microbes. As we have all learned in this time of Covid-19, countless types of microorganisms inhabit our bodies, inside and out, and when an astronaut arrives on the station, they bring their specific collection of microbial “hitch hikers” with them. A new study shows that the microorganisms living on surfaces inside the space station so closely resembled those on an astronaut’s skin that scientists could tell when this new crew member arrived and departed, just by looking at the microbes left behind. Many of the microorganisms living in and around us are harm less or even essential for good health, but some can cause disease or damage structures in built environments.
