NASA announced on May 13, 2013 that AMSAT’s Fox-1 amateur radio spacecraft has been assigned for launch in November 2014 on the ELaNa XII mission. The expected orbit is 470 x 780 km at 64 degrees inclination. This orbit has a lifetime of about 11 years.

AMSAT Vice President Engineering, Tony Monteiro, AA2TX, reported that the software development team successfully brought up the Fox-1 system software on the Internal Housekeeping Unit (IHU). The IHU is the brains of the Fox-1 satellite and it has a 32-bit, STM32L microprocessor. The operating IHU card was shown in the AMSAT Engineering booth at the Dayton Hamvention.

AMSAT FOXThe Fox-1 Engineering Team will deliver the satellite for integration with the launch vehicle during May, 2014 with the launch scheduled for November, 2014. Tony commented, “While this is later than we had hoped, it is well within the normal variance of ELaNa launch dates and the extra time will be most welcome for additional satellite testing. This is very exciting news and really puts the focus on finishing the satellite and ground station software development.”

President Barry Baines says, “AMSAT’s focus on STEM education and development of a CubeSat platform capable of flying a science mission with a reliable communications link resulted in the selection of Fox-1 in the third round and RadFxSat (Fox-1B) in the fourth round of NASA’s Cubesat Launch Initiative.”

All Fox CubeSats are designed to host advanced science payloads to support future science missions that help us to continue qualify for NASA ELaNa (free) launches. The Phase 1 Fox satellites are 1-Unit CubeSats. They each include an analog FM repeater that will allow simple ground stations using an HT and an “arrow” type antenna to make contacts using the satellite. This was the mode made so popular by AO-51. The Phase 1 CubeSats also have the capability of operating in a high-speed digital mode for data communications. Phase 2 Fox satellites will include software-defined-transponders (SDX) like the one tested on ARISSat-1. These will be able to operate in a wide variety of analog and digital communications modes including linear transponders. Since this requires more power for reliable operation, these will probably all be 3-Unit CubeSats.

A 1U CubeSat, Fox-1a will serve as a communications relay for radio amateurs worldwide via the onboard FM repeater system. Fox-1a will also carry an experiment consisting of a 3-axis MEMs gyro developed by Penn State University. The communications and experiment missions will run concurrently. An uplink on 435.180 MHz for FM voice and a downlink on 145.980 MHz with FM voice and an optional sub audible FSK digital carrier channel has been coordinated. Fox-1a will employ passive magnetic stabilization.

Fox-1 has a Launch Date!



NASA announced Monday that AMSAT’s Fox-1 FM transponder spacecraft has been assigned a launch in 2014. For details on the launch vehicle, targeted launch date, orbit specifics, and more, please attend the AMSAT Forum and visit the AMSAT booth at the Dayton Hamvention this weekend.  Watch and the AMSAT News Service for more details to follow as they become available.

AMSAT’s Fox-1 CubeSat aims to provide these features:

• Fox-1 is designed to operate in sunlight without batteries once the battery system fails. This applies lessons learned from AO-51 and ARISSat-1 operations.

• In case of IHU failure Fox-1 aims to continue to operate its FM repeater in a basic, ‘zombie sat’ mode, so that the repeater remains on-the-air.

• Fox-1 is designed as the immediate replacement for AO-51. Its U/V (Mode B) FM transponder will make it even easier to work with modest equipment.

• From the ground user’s perspective, the same FM amateur radio equipment used for AO-51 may be used for Fox-1.

John Heath G7HIA – Silent Key

AMSAT-UK is very saddened by the passing of John Heath, G7HIA. He was a long standing member of AMSAT-UK, and contributed to the amateur space programme in many ways during his lifetime.

John was a regular attendee at the annual AMSAT-UK Colloquia for many years and he enjoyed meeting up with his friends who shared his passion for satellites.  Sadly his ill heath in recent years prevented his attendance.

In the days before his passing, John was in contact with AMSAT-UK; and made a significant financial contribution to the FUNcube project. He chose to do this by making the donation via the Radio Communication Foundation, which, as a registered charity will be able to claim any income tax paid by John as Gift Aid. The size of his donation is very considerable, and will be used at the discretion of the AMSAT-UK committee. Such is the extent of his generosity, that it may be feasible to consider the construction of a further complete CubeSat.

AMSAT-UK is very grateful for this donation.

John will be sadly missed by all members of AMSAT-UK who knew him during his life, and we send our condolences to his family.

RIP, John

I was very saddened to learn of John’s passing.  We had exchanged many e-mails during the last few years. I didn’t know John very well, although we had met at the ASAT-UK Colloquium on several occasions. Topics we discussed by e-mail included processing Delphi 3C telemetry, OSCAR-11 spin rate, automatic Doppler tracking and ARISSat-1 decay.

John was very active in using our satellites and promoting their use to others.  For several years he was net controller of the Midlands two metre AMSAT net.  He also wrote the Space column for RSGB’s RadCom magazine for a number of years. He contributed many articles to OSCAR News, recently in the September 2012 issue about ARISSat-1 orbital decay. His last contribution to OSCAR News was a short item in the December issue, congratulating AMSAT-UK on their 200th issue of the magazine. He included a photograph of himself, Astronaut Ron Parise WA4SIR and Geoff Perry, founder of the Kettering Group of satellite observers. It was taken at the 1998 Colloquium.

During the course of our discussions John mentioned that he was having some unpleasant hospital treatment. He also told me about his working career, which I  thought may be of interest.

As a teenager he was interested in organic chemistry and went to work in industry, eventually in the R&D department at Bakelite in Tyseley, Birmingham. In the 1960’s/70’s he worked on the phenolic resins used to make copper clad PCB material, and did the first industrial synthesis on nonyl phenol by ion exchange. There were massive world stocks of Nonene at knock down prices so they were looking for a way to use it to make phenol/formaldehyde resins used in PCB manufacture.

His YL Pam at that time worked in a small hairdressing supplies business and he sometimes worked with her when they needed extra staff to cover late night opening. After his marriage to Pam, her firm decided to open a branch in Leicester and they were offered the opportunity to re-locate and run the new operation. Together they built up the business, diversifying into related activities with a skin care manufacturing  company (where his science background was invaluable), a beauty products wholesale business  and a  mail order operation. The business expanded from 6 people to a staff of nearly 200 on four sites.

John said that Amateur radio helped to keep him sane by giving him a totally different set of things to think about and emptied his head of business concerns for a few hours each week!

A few years ago Pam was diagnosed with a serious illness and confined to a wheel  chair. This caused them to  bring forward their retirement plans and they moved to Devon.

My condolences to Pam, family & friends.

RIP John, we will miss you.

TURKSAT-3USAT to launch with V/U Linear Transponder

Preparing for TAMSAT linear transponder tests

Preparing for TAMSAT linear transponder tests

TURKSAT-3USAT is a three unit CubeSat built jointly by TURKSAT and the Istanbul Technical University (ITU).

Members of AMSAT-TR (TAMSAT), the Turkish Amateur Satellite Technologies Organisation, have designed and implemented a V/U linear transponder for the satellite to provide amateur radio SSB/CW communications. The transponder input is 145.940-145.990 MHz and the output is 435.200-435.250 MHz, there will be a CW beacon on 437.225 MHz.

TAMSAT V/U Linear Transponder Test

TAMSAT V/U Linear Transponder Test

The VHF/UHF transponder and all other subsystems, except the stabilization, are doubled for redundancy. Where possible, both COTS systems and in-house development are employed.

The power is provided using solar panels and lithium polymer batteries together with super capacitors. Satellite stabilization is accomplished using passive magnetic attitude control system with hysteresis rods. There is a camera payload to take images of the Earth.

TURKSAT-3USAT is expected to launch on April 26 at 0413 UT on a CZ-2D rocket from the Jiuquan Space Center into a 680 km Low Earth Orbit (LEO). The satellite has a de-orbiting system which will make it re-enter the atmosphere at the end of its operational life.

On February 9, 2013 TAMSAT President A. Tahir Dengiz, TA2T, and Vice-President Barış Dinc, TA7W, were at the laboratory in the Istanbul Technical University (ITU) where tests were carried out on the transponder.

On the AMSAT bulletin board Raydel Espinet CM2ESP reports that more Cuban radio amateurs have become active on the satellites. He writes:

As many of you should already know, now we have two new Cuban Amateur Operators on FM Satellites. Recently CO7WT and CM2XN have finally achieve their first QSO on SO-50 Satellite. This may look simple, but for a Cuban Ham this is a great success, after many weeks of antenna building, equipment adjustments and learning, this two fellow hams enjoy of the amazing opportunity of make a QSO on a FM Transponder Satellite. They know there is a lot more of operating skills to learn and they are very happy to do so.
