IARU Region 1 has released the papers for the Interim Meeting to be held in
Vienna April 15-17, 2016.

Among the papers for the C5 VHF/UHF/Microwave Committee is one on
harmonizing APRS.

VIE16_C5_41.pdf 144 /435 MHz APRS Harmonisation

The paper covers global band planning considerations and among the
recommendations says:

Emphasise that spaceborne APRS must be confined to globally coordinated
amateur satellite sub bands. Therefore items that are ambiguous and
generate confusion in national band plans such as ‘Space communications’
and ‘New Oscar Sub band’ should be removed as soon as possible in all
Regions in accordance with IARU-AC and Satellite Coordination guidance

It is believed that ‘New Oscar Sub band’ refers to the USAs ARRL 144 MHz
band plan andÂ*‘Space communications’Â* to the Australian WIA 144 MHz band
plan. These band plans, as well as those for some other countries, show
144.300 144.500 MHz as being for Amateur Satellite use.

The AggieSat4 satellite carrying the Bevo-2 CubeSat is expected to be
deployed from the International Space Station (ISS) on January 29, both
have amateur radio payloads.

Below is a timelapse of the build process of the Texas A&M student-built
satellite, AggieSat4. The video spans an entire year, the amount of time it
took to build AGS4, however many more years were put into the design and
programming of AGS4 before any hardware was assembled.

AggieSat4 was launched aboard the Orbital ATK Cygnus OA-4 cargo resupply
mission. The Cygnus spacecraft was mounted atop a United Launch Alliance
Atlas V rocket that took the Cygnus from the Kennedy Space Center up into
Low Earth Orbit on December 6 at 4:44pm EST.

AGS4 is planned to release from the ISS on January 29 and will then proceed
to eject the University of Texas CubeSat, Bevo-2 and perform relative
navigation tasks as well as take pictures of the release of Bevo-2.

The IARU has coordinated these frequencies for the amateur radio payloads:

AggieSat4 436.250 MHz 9k6 FSK telemetry (also 153.6 kbps FSK)

Bevo-2 437.325 MHz CW and 38k4 FSK
