AMSAT NEWS SERVICE ANS-319
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 satellites.
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 transponder 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 health.
The precursor satellites have gathered valuable data about the sensor payloads, and the lessons learnt are being implemented in the flight units for the QB50 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.

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 - 03:40 UTC. This satellite is in a 6° inclination orbit so only stations in equatorial 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 [email protected]
The two-line Keplerian elements are:
IO-86 1 40931U 15052B 15316.15776324 .00001070 00000-0 60618-4 0 9994 2 40931 6.0030 69.3893 0012877 275.6206 84.2533 14.76374433 6653

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 1970s 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 search and rescue regions.
McMurdo has announced that it has completed the installation of a six-antenna next-generation Medium-Earth Orbit Search and Rescue (MEOSAR) satellite ground 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 next- 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 creates 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 beacon locations identified with greater accuracy thereby reducing this time to minutes.
The New Zealand MEOSAR system, and another being installed in Western Australia, 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.
