Where.
UlCS_TT_SNR_PRN
Bits 0-7: PRN (PRN is 0 if no data)
Bits 8-15: SNR value (SNR= 10.0 * log
10
* (0.8192 * SNR value))
Bits 16-23: Phase Track Time in units of 1/10 second, range = 0 to 25.5 seconds
(see next word)
Bits 24-31: Cycle Slip Counter (Increments by 1 every cycle slip with natural
rollover after 255)
UlDoppler_FL
Bit 0: 1 if Valid Phase, 0 otherwise
Bit 1: 1 if Track Time > 25.5 seconds, 0 otherwise
Bits 2-3: Unused
Bits 4-31: Signed (two’s compliment) Doppler in units of m/sec x 4096. (i.e.,
LSB=1/4096), range = +/- 32768 m/sec. Computed as phase change over 1/10
sec.
