OSCAR Number Administrator Bill Tynan W3XO has announced that the Nayif-1
CubeSat has met all the requirements necessary to be issued with an OSCAR
number.

In accordance with the request sent to the AMSAT-NA Board of Directors for
an OSCAR number for the UAE CubeSat, Nayif-1, and the statement that all of
the conditions for an OSCAR number have been met, I hereby by the authority
vested in me by the AMSAT-NA president, do convey on Nayif-1 the
designation Emirates Oscar 88 or EO-88.

Along with the rest of the Amateur Radio satellite community, I hope that
EO-88 will meet all of its objectives.

I wish you and your group the best of luck in this and future endeavors to
keep Amateur Radio in space.

Weather permitting there will be a 434 MHz pico balloon launch from Bristol
on Tuesday, February 28 at or after 0830 GMT.

Richard Meadows M0SBU from University of Bristol Students for the
Exploration and Development of Space (UBSEDS) writes:

This launch is using a 1.5m envelope and the attempted float altitude will
be about 12 km.

The payload is a new tracker design that uses an AX5043 radio. It will be
transmitting pips, RSID and Contestia 16/1000 on 434.635 MHz USB, once
every two minutes. Callsign UBSEDS23.

Between the Contestia transmissions the AX5043 radio will also be used to
transmit GMSK at 24 ksymbol/s, centered on 434.637.5 MHz. Its 44
interleaved, R=1/2 convolutional K=5, HDLC framing, whitened etc. as per
the AX5043 manual.

This is concatenated with RS(255,223) to mop up some burst errors. IQ
recordings of this might be useful so that the data can be extracted once a
software decoder exists. Callsign UBSEDS23G.
