The AMSAT News Service bulletins are a free, weekly news and infor-
mation service of AMSAT North America, The Radio Amateur Satellite
Corporation. ANS publishes news related to Amateur Radio in Space
including reports on the activities of a worldwide group of Amateur
Radio operators who share an active interest in designing, building,
launching and communicating through analog and digital Amateur Radio

The news feed on http://www.amsat.org publishes news of Amateur
Radio in Space as soon as our volunteers can post it.

Please send any amateur satellite news or reports to:
ans-editor at amsat.org.

In this edition:

* AMSAT Forum Speakers at Dayton
* Just-Launched ISS Expedition 47/48 Crew Increment Includes Two Radio 
* UK Student Balloon Crosses Pacific

"AMSAT Status Report" Barry Baines, WD4ASW, AMSAT-NA President, will
highlight recent activities within AMSAT and discuss some of our
challenges, accomplishments, projects, and any late breaking news.

"AMSAT-NA Satellite Program" Jerry Buxton, N0JY, AMSAT-NA Engineering Vice
President, will review the upcoming launches of four Fox spacecraft and
exciting new engineering developments.

"AMSAT's HEO and GSO Plans" Bob McGwier, N4HY, AMSAT-NA Director, will
discuss AMSAT-NA opportunities for High Earth Orbit and Geo-Synchronous
Orbit satellites.

"AMSAT Satellite Operations" Drew Glasbrenner, KO4MA, AMSAT-NA Operations
Vice President, will survey the current operational amateur satellites, as
well as those planned for launch in the next year.

"ARISS Report 2016" Frank Bauer, KA3HDO, AMSAT-NA Vice President for Human
Spaceflight, will discuss ARISS developments & operation on the
International Space Station.

"Teaching STEM Using the Fox Satellites” Joe Spier, K6WAO, AMSAT-NA
Educational Relations Vice President, will explain how the Fox MEMS
gyroscopes, radiation experiments, and cameras will be used to teach
Science, Technology, Engineering, and Math (STEM).

Just-Launched ISS Expedition 47/48 Crew Increment Includes Two Radio 

The Expedition 47/48 crew increment of Astronaut Jeff Williams, KD5TVQ, and
Cosmonauts Oleg Skripochka, RN3FU, and Alexey Ovchinin, is on its way to the
International Space Station (ISS). Their Soyuz TMA-20M launched from the
Baikonur Cosmodrome in Kazakhstan on March 18 at 2126 UTC. The trio now is
safely in orbit.

“During their 6-month mission, the expedition crew members will facilitate
approximately 250 research investigations and technology demonstrations not
possible on Earth,” NASA said. “Science conducted also will enable 
future long-
duration human and robotic exploration into deep space and on the agency’s
journey to Mars.”

Williams, Skripochka, and Ovchinin will join Expedition 47 Commander Tim 
KE5UDN, European Space Agency astronaut Tim Peake, KG5BVI/GB1SS, and 
Yuri Malenchenko, RK3DUP. Williams will take command of the station on 
June 4
for Expedition 48. The three will return to Earth in early September.

This mission marks Williams’ fourth spaceflight and will be his third long-
duration stay on the orbiting laboratory — a first for an American. It’s 
his first time back to the ISS since its completion in 2011. By the time his
duty tour ends in September, Williams will become the new American 
record holder
for cumulative days in space — 534 — surpassing Expedition 46 Commander 
Kelly, who wrapped up his 1-year mission on March 1.

UK Student Balloon Crosses Pacific

On Thursday, March 17 the UBSEDS14 balloon, launched by University of 
students, had successfully crossed the Pacific and was above Arizona, having
traveled over 24,500 km since launch.  By March 19 the balloon had 
crossed the
United States and was headed out across the Atlantic Ocean.

The University of Bristol Students for the Exploration and Development 
of Space
(UBSEDS) launched their balloon on Monday, March 8. Powered by a single AA
Lithium Energiser Battery (LR91) the balloon has been transmitting about 
5dBm of
Contestia 16/1000 on 434.600 MHz USB at 4 minute intervals as well as APRS
during its flight at an altitude of about 11,000m.

The balloon uses the error-correcting Contestia 16/1000 mode on 434.6MHz 

The transmission power on this band was measured to be +5dBm on a 
similar board,
which is well below the +10dBm limit for ISM band operation. Each packet was
preceded by 10 seconds of 1Hz pips for manual alignment and a RSID tone for
automatic alignment with suitable software (dl-fldigi for example). For many
countries the balloon transmits APRS packets on local frequencies. In 
this is 144.8MHz in Europe, 144.66MHz in Japan and 144.39MHz in North 

The balloon has a diameter of 1.5m and the payload weighs just 21.3 grams.
Despite the weight constraints the team have managed to employ sophisticated
Geofencing technology to prevent the balloon transmitting when over certain
countries and also to select different APRS frequencies depending on the
territory being overflown.

UBSEDS14 information is available at

One of the students involved in the project is Richard Meadows M0SBU. He 
the amateur radio courses run by the Chelmsford Amateur Radio Society 
(CARS) at
Danbury in Essex. Further information on the courses is available from
