[time-nuts] update on SARSAT and Galileo

[Jeffrey Pawlan]

The current issue of Inside GNSS has a final update on Galileo and GPS
bandplans and the coding for each signal.

Galileo will carry the new SARSAT, receiving from 406 to 406.1MHz then
broadcasting these signals on sub-carriers of downlinks from 1544 to 1545MHz.

Unfortunately, it was announced that Galileo will transmit multiple modulations
plus pilot tomes in the amateur radio band at 1278.75MHz.  This will not likely
affect terrestrial amateur radio communications but it would definitely affect
very weak signal Earth-Moon-Earth communications which are always done from
1296 - 1297MHz and our antennas are pointed at the moon but the antenna
beamwidth is usually 10 - 20 degrees wide.
