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.

EO-79 CubeSat Update

Wouter Weggelaar PA3WEG has provided this update on the status and plans for
QB50p1 – EO-79.

Earlier testing campaigns indicate that the AMSAT-UK/AMSAT-NL transponder on
board of this spacecraft is in good health. We have activated the 
transponder on
various occasions for testing purposes.

At the moment we believe the power system is capable of sustaining 
operations indefinitely. ISIS (the satellite designer and operator) 
still needs
to write and apply a software patch that would keep the transponder 
running. The
current logic in the satellite will switch off the transponder if a 
reset occurs
of the On Board Computer or power system.

Efforts are being made to allow usage of the transponder in the mean 
time and
also allow select command stations to take the satellite out of safe 
mode if it
does reset. ISIS will continue to monitor all telemetry and the satellites

The precursor satellites have gathered valuable data about the sensor 
and the lessons learnt are being implemented in the flight units for the 
main mission.

We will still have to wait until procedures are in place and the 
activation is
cleared by the operator and owners of the satellite, but we are nearly 
ready for
the activation of another transponder!

Transponder activations will be announced on the AMSAT Bulletin Board.

On behalf of AMSAT-NL and the ISIS operations team I would like to thank the
community for supporting our mission and thank you for your patience.

Newsline Interview With ISS First School Contact Teacher

This week’s Amateur Radio Newsline Report 1985 November 13, 2015 includes an
interview with Rita Wright, KC9CDL, the science teacher who was lucky 
enough to
help her students be chosen to talk with ISS astronaut William M. “Shep”
Shepherd, KD5GSL, for the first school contact with the International Space

Signal Reports Requested From IO-86 FM Transponder Test

The FM transponder aboard IO-86/LAPAN-ORARI was activated for testing, 
and was
available for amateur radio use on 14 November 2015 between 01:35 UTC - 
UTC. This satellite is in a 6° inclination orbit so only stations in 
regions have access. Station in far southern United States may have access.

+ Uplink:   145.880Mhz with 88.5 Hz tone
+ Downlink: 435.880 Mhz

If you heard IO-86 or had any contacts please e-mail signal reports to
yd1eee @ gmail.com

The two-line Keplerian elements are:

1 40931U 15052B   15316.15776324  .00001070  00000-0  60618-4 0 9994

McMurdo completes MEOSAR satellite ground station in New Zealand

The legacy of AMSAT OSCAR 6 & 7 in demonstrating satellite based Doppler
location of ground transmitters for search-and-rescue operations in the 
set the stage for the Cospas-Sarsat system which is now entering into 
the next
stage of evolution.

McMurdo's next-generation MEOSAR satellite ground station system 
installation in
New Zealand will reduce rescue times in one of the world's most active 
and rescue regions.

McMurdo has announced that it has completed the installation of a 
next-generation Medium-Earth Orbit Search and Rescue (MEOSAR) satellite 
station system in New Zealand.

The project, which is part of a joint initiative with Maritime New 
Zealand and
the Australian Maritime Safety Authority, is expected to significantly boost
search and rescue capability in the New Zealand and Australia search 
regions and
marks the first implementation of MEOSAR in Asia Pacific. MEOSAR is the 
generation version of Cospas-Sarsat, the international search and rescue
satellite system that has helped to save 37,000 lives since 1982.

In a typical satellite-based search and rescue scenario, ships, aircraft or
individuals transmit distress signals from an emergency location beacon via
satellite to a fixed ground receiving station or local user terminal. 
The ground
station receives and calculates the location of the distress signal and 
and sends an alert to the appropriate rescue authorities.

Today, the beacon-to-alert process depends on a limited number of Low Earth
Orbit (LEO) satellites and may take several hours before a position is
confirmed. With MEOSAR, beacon signals will be received more quickly and 
locations identified with greater accuracy thereby reducing this time to

The New Zealand MEOSAR system, and another being installed in Western 
will cover one of the largest search and rescue areas in the world - 
from north
of Australia/New Zealand to the Equator and south to the South Pole, east to
half way across the Pacific, and west half way across the Indian Ocean. The
systems will undergo rigorous testing before being officially brought 
online in
late 2017 by Cospas-Sarsat.
