OSC_DRIFT_ERR too much clock drift 60HZ for XO, 7.5HZ for
TCXO 62 BAD_DOPPLER_ERR too big Doppler errors 4m/s 63
BIG_RANGE_RESID 110m/40m depend on virtual ttagl/ DGPS factors
64 BIG_DOPPLER_RESID 0.7m/s 65 HUGE_RANGE_RESID 10km
normal for postfit residuals for range 66 HUGE_DOPPLER_RESID
100m/s normal for postfit residuals for doppler Usually, Bad code is 20
and 23. If fix is good, it would be 0.
