*UPRM CGPS on @ 17:00:00 UTC - 0.5 s sync


Made 3 beam programs.  One program was 2.9 mrad and the other 1.9 mrad divergence. 
The following items were modified:  added time 80, fixed start sector to 4 million, 
mdelay to 15,000, and started galvonometer position at OXC000.

*Programs are Aspi3big.c and Aspi3Bm.c

GPS was turned on at 9:00am, and both receivers were nominal.


2A and 3A fuses were bown in SVEN.  Replaced fuses with 4A. (fast blow)
Turned on at 24 degrees C.  No problems so far.
