Announcing EO-79 transponder testing for one full orbit – May 4

Wouter Weggelaar PA3WEG from AMSAT-NL reported via the AMSAT-BB that
on Monday May, there is a fairly high chance that the AMSAT-NL
transponder will be tested for one full orbit.

Details will be made available on short notice, but the target time
for an activation starts at approximately 08:30 UTC and may last
until about 10:10 UTC.

The aim of the test is to characterize the power budget on board EO-
79. Usage of the transponder is being encourage. Please also report
the QSOs and signal reports to pa3weg at amsat.org

EO-79 / QB50p1 First Transponder Test Success

AMSAT-NL is delighted to announce that an initial series of tests of
the FUNcube transponder payload aboard the QB50p1 CubeSat have been
successfully completed.

QB50p1 is one of two QB50 precursor spacecraft that were launched
from Yasny in Russia in June 2014.

The primary science payloads are still being extensively tested but
it has now been possible to undertake a short test of the transponder
payload as well. The transponder is intended as a long term secondary
mission following the initial technology demonstration and de-risking
phase.

After spending ten months in space, the transponder was commanded on
for short periods during each of the three morning passes over Europe
on Monday 27th April 2015. A number of FUNcube team members in the
Netherlands and in the UK were standing by to run through a
predefined test plan.

The transponder has a similar performance to that of FUNcube-1 but
the passband is nominally 5 kHz wider by design.

It is not yet known when this transponder may be available for
regular usage but AMSAT-NL is delighted to be able to report that the
hardware is functioning and is very grateful to the QB50 project, the
Von Karman Institute and ISIS B.V. for their ongoing support.

AMSAT-SM donates $1600 USD for the FOX satellite project

“AMSAT-SM believe that FOX project is very important to continue to
develop amateur radio on board satellites. We therefore hope that our
contribution can help the FOX satellites up in space.”

AMSAT-SM in Sweden has aprox 150 members. Membership is currently
free and registration is done online at our website: www.amsat.se

Med glädje kan vi läsa om att AMSAT-NA (USA) har fått en möjlighet att “följa med” på en geostationär satellit under 2017. Detta innebär att vi kanske kan få två geostationära transpondrar uppe för amatörradio om bara några år!

Projektet kommer även innebära att en lågbudget markstation kommer tas fram så att det ska bli möjligt för många att köpa in billig utrustning.

AMSAT is excited to announce that we have accepted an opportunity to
participate in a potential rideshare as a hosted payload on a
geostationary satellite planned for launch in 2017. An amateur radio
payload, operating in the Amateur Satellite Service, will fly on a
spacecraft which Millennium Space Systems (MSS) of El Segundo, CA is
contracted to design, launch, and operate for the US government based
on their Aquila M8 Series Satellite Structure.

A meeting to discuss this potential rideshare took place on April 13
at Millennium Space Systems that included Dr. Bob McGwier, N4HY;
Franklin Antonio, N6NKF, co-founder of Qualcomm; Jerry Buxton, N0JY,
AMSAT Vice President of Engineering and member of the board for AMSAT-
NA; Dr. Tom Clark, K3IO, Director and President Emeritus of AMSAT-NA;
Phil Karn,KA9Q; and Michelle Thompson, W5NYV.

Hosting the meeting for MSS were Stan Dubyn as founder and chairman
of MSS, Vince Deno as president of MSS, Jeff Ward, K8KA, of MSS as VP
for Product Development, formerly with SSTL and University of Surrey
Space Center, and Ryan Lawrence of MSS as Project Manager on the
spacecraft mission. Attending by telephone were Dr. Jonathan Black,
Associate Research Director of Hume Center for Aerospace Systems and
Associate Professor of Aerospace and Ocean Engineering and Dr.
Michael Parker, KT7D, founder of RINCON Research Corp.

Following the meeting, Dr. Bob McGwier, N4HY, Director of Research
at the Hume Center for National Security and Technology of Virginia
Tech, and former director and former VP Engineering of AMSAT,
described this as an opportunity to go forward with “AMSAT-Eagle”
which, in the 2006-2008 timeframe, evolved into a microwave payload
to be flown to geostationary orbit as a hosted payload. It would have
provided digital communications to small terminals on the ground and
a linear bent pipe transponder had it flown. This failed to go
forward in part due to lack of an affordable flight opportunity.

McGwier outlined the next steps toward developing this mission:

1) To organize an effort at Virginia Tech to make a firm proposal
to MSS and its US government sponsor, and organize an effort
to raise sufficient funds to pay for development of the mission.

2) Enable Dr. Jonathan Black to lead the construction project at
Virginia Tech in the Space@VT Center. Sonya Rowe, KK4NLO, Project
Manager at the Hume Center will be the project manager.

3) Work for development of a low-cost microwave ground station for
amateur radio still needs to be determined.

4) Dr. Michael Parker, KT7D, will solicit the cooperation of the
Rincon Research Corp. for development of the software radio
technology for this payload.

The AMSAT Board of Directors has accepted the invitation to
participate in this potential rideshare payload opportunity. AMSAT
expects to be involved in the development of the ground station and
the payload RF development, and will serve as the amateur radio
(hosted) payload operator once the satellite has been launched.

McGwier summarized, “The launch is currently scheduled for 2017 and
the payload must be delivered for testing and integration by Spring
of 2016. It is an ambitious schedule and all involved will have to
gain and maintain a serious level of commitment to that which they
agree to undertake.” AMSAT President, Barry Baines, WD4ASW, said,
“The AMSAT leadership is excited to fly a Phase-IV geostationary
amateur satellite payload. This is an evolving development as we
collaborate with the VT Hume Center with a project that provides
technical challenges to create a new amateur radio capability in
space that will provide a variety of benefits not only for amateurs
but also for emergency communications and STEM educational outreach.”

The transponder is expected to support a wide range of voice,
digital, and experimental advanced communications technologies. A
decision is expected soon specifying the microwave uplink and
downlink bands.

Fox-1C and Fox-1D Include L-Band Uplink; Fox-1E Linear Transponder Announced

AMSAT Vice President – Engineering Jerry Buxton, N0JY, announced plans to
incorporate an L band receiver in Fox-1C and Fox-1D. The addition will allow
ground commanded selection of the U/v (normal Fox-1 bands) or the new L/v
1.2 GHz (23 cm) mode. Both bands will operate as FM single channel.

Rather than adding a complete new receiver, the L band “Project Downshifter”
will convert the received L band signal down to the Fox-1 uplink frequency
and feed it to the regular UHF receiver on the Fox-1 satellite. The design
will not require an additional antenna on the satellite because the existing
UHF antenna will work for L band receive as well.

In concert with the development of the satellite segment, a new group of
volunteers is working on a companion uplink station to convert UHF to the L
band uplink frequencies:

+ Bruce Herrick, WW1M
+ Dan Hubert, VE9DAN
+ Elizabeth Schenk, KC1AXX
+ Dave Smith, W6TE
+ Alfred Watts, AF5VH

The team is planning to have an affordable L band uplink ground station
available to amateurs by the time Fox-1C is on orbit.

In further news, Jerry announced the plan to construct a Fox-1E “Evolution”
variation of the Fox-1 series which will carry a Mode J linear transponder.
The transponder is planned to be 30 kHz wide and will also include a 1200
bps BPSK telemetry beacon. The purpose of the project is to test a design for a
linear transponder that could be made available to CubeSat builders as a
secondary, or even primary radio payload thus bringing more opportunities for
amateur radio in space as well as offering AMSAT’s proven communications skills
as a telemetry option.

AMSAT has been approached for a launch opportunity for Fox-1E in 2016, but
launch details can not be shared at this time.

Jerry concluded, “It is important that we find additional resources to help
the Fox-1 Team with these new endeavors. We are looking for volunteers who
have solid RF building and testing experience to work on both the
downshifter and the transponder prototyping and construction.” If you would
like to help and be a part of the success of Fox-1C/D and Fox-1E, please
