AMSAT’s GOLF-TEE CubeSat Manifested for Launch on ELaNa-46

AMSAT’s GOLF-TEE CubeSat has been manifested for launch on NASA’s ELaNa-46 mission.

GOLF-TEE is the first satellite in AMSAT’s “Greater Orbit, Larger Footprint” or GOLF program. The goal of the GOLF program is to work by steps through a series of increasingly capable spacecraft to learn to develop systems and skills needed to achieve successful high orbit missions. Among these are active attitude control and the ability to command attitude changes, deployable/steerable solar panels, radiation tolerance for commercial off the shelf (COTS) components in higher orbits, and propulsion. The eventual goal of the GOLF program is a satellite in Highly Elliptical Orbit (HEO) similar to AO-10, AO-13, and AO-40, but at a currently affordable cost combined with significantly enhanced capabilities, which in turn will allow the use of much less complex ground stations.

The -TEE designation in GOLF-TEE stands for “Technology Exploration Environment” reflecting GOLF-TEE’s mission testing two primary systems needed for higher orbits. First, an Attitude Determination and Control (ADAC) system will be tested to allow active pointing of the satellites antennas, which will have significant gain. The other primary goal of GOLF-TEE is to gain initial orbit and space radiation exposure for radiation event-induced fault tolerant systems designed using COTS components. GOLF-TEE will carry an Integrated Housekeeping Unit (IHU) / command transceiver designed using the Hercules line of ARM architecture-based microcontrollers.

GOLF-TEE will also evaluate a low-cost, deployable, fixed attitude, solar panel array design as part of AMSAT Engineering’s exploration of fixed panel arrays that allow for outfitting a variable number of “wings” in order to best match the power requirements of various CubeSat missions.

Additionally, GOLF-TEE will carry a modified commercial software-defined radio (SDR), the Ettus E310, as an experimental package to test high speed data downlink in the 10 GHz band.

GOLF-TEE will also be a fully-functional LEO VHF/UHF amateur satellite carrying conventional backup systems, including a linear transponder, similar to those flown on AO-109.

A significant amount of funding is necessary to complete the development and construction of the GOLF series of CubeSats. Please consider a donation today. Donations designated for the AMSAT GOLF program may be made at

SMOG-1 Designated Magyar-OSCAR 110 (MO-110)

On March 22, 2021, the Budapest University of Technology and Economics SMOG-1 PocketQube was launched on a Soyuz-2-1a Fregat launch vehicle from the Baikonur, Kazakhstan. SMOG-1 carries RF spectrum monitoring and total ionizing radiation experiments. Further information is available at

At the request of the Budapest University of Technology and Economics, AMSAT hereby designates SMOG-1 as Magyar-OSCAR 110 (MO-110). We congratulate the owners and operators, thank them for their contribution to the amateur satellite community, and wish them a long mission and continued success on this and future projects.

AMSAT FTP Site Retired

The AMSAT File Transport Protocol (FTP) server has been retired as of 15 April 2021. Content formerly hosted on that server is now available at

The FTP server provided an important service for distributing software, bulletins and other information going back to at least the early 1990’s when internet access started to become available to the general public. Over time the overwhelming success of the web and ubiquitous use of the web browser have evolved to provide the same capability, and today even heavy internet users are unfamiliar with FTP. The decision was made to stop spending scarce volunteer resources maintaining this seldom used service.

TO-108 Operational Update

TO-108 (CAS-6) was launched in December 2019 and carries a 20 kHz wide UHF/VHF linear transponder. When originally made available for amateur radio use in June 2020, the transponder operated only intermittently, approximately 2 seconds on and 5 seconds off.

On April 12, 2021, EI2IP posted a video on Twitter where he calls CQ for a few minutes on the satellite. Later tests by European stations including SA2KNG and DO1AM showed that the transponder is still only operational intermittently, but now the transponder is on for minutes at a time instead of only a couple of seconds.

TO-108’s linear transponder’s uplink passband is 435.270 MHz – 435.290 MHz and the downlink passband is 145.915 MHz – 145.935 MHz. The CW beacon is at 145.910 MHz and 4.8k GMSK telemetry at 145.890 MHz. Observations indicate that the transponder is operational when the beacon is transmitting continuously.

CAMSAT Applies for Frequency Coordination for CAS-9 (XW-3)

CAMSAT has applied for frequency coordination for their CAS-9 satellite, also known as Hope-3 or XW-3. CAS-9 will be a 6U CubeSat carrying a 30 kHz VHF/UHF linear transponder.

In addition to the linear transponder, there will be a UHF CW beacon and UHF 4.8k/9.6k AX.25 GMSK telemetry downlink.

Launch is planned for December 15, 2021 from Jiuquan Satellite Launch Center into a 770 km circular orbit with an inclination of 98.58 degrees.

Upcoming Satellite Operations

ND9M: I’m doing another tour on my merchant marine ship. We’ll be leaving the States (EM90) in a few days to head for the western Pacific by way of the Panama Canal. I’ve got my FT857 / FT817 with an Elk although I don’t hear RS-44’s downlink all that well. (AO-27’s downlink on the same band is great though.) I’m planning to be active on as many satellite passes that I can fit in around job duties; since I’m a staff of 1, working all seven days and being on call 24/7 can get in the way. My internet connection on board is marginal at best and will become virtually nil for several days as we approach Panama and then hit the Pacific. I’ll post likely grids a day or two in advance to the AMSAT-BB and will hit Twitter (@ND9M) when I’ve got a web connection.

WY7AA: April 17th – May 2 EM86 vacation style FM and SSB. I will have a day trip to EM85, but I will plan that and advertise when I get there.

Major Roves:

CM93 Possibility: N6DNM Very long shot, but might want to put it on your calendar for May 15th, if you can figure out where it is and for SOTA folks, that would be W6/SC-336, Santa Rosa Island, activated only once before.

I, Italy:
Loriano/IZ5RHU and the ARI section Grosseto commemorate the
Chernobyl disaster between April 18 and May 9 as II5RCH on 80-2m
(CW, SSB, digital modes) and via satellite. QSL via IZ5RHU (d/B).
