Appendix B
110
17
ILL_DEFINED_2D_MATRIX
2X2 matrix can not be inverted in 2D fix
20
NO_SAT_TIME
no satellite time
23
NOT_ENOUGH_SATS
no enough satellite for 2D or 3D fix
24
CANNOT_SELECT_FIX_TYPE
30
VELOCITY_2D_ONLY
2 satellite fix only for velocity, no position fix
31
BAD_VELOCITY_PDOP
50 too big pdop for velocity
32
TOO_MANY_SATS_FOR_2D_VEL there are 4 or more satellites, but 2D fix provided
51
WRONG_NUMSAT
number of satellite for fix > 12 or less 2
56
LOOP_3D_NOT_CONVERGING 3D initial fix is not convergent
57
MILLISECOND_ERROR
millisecond jump happened
58
LOOP_2D_NOT_CONVERGING 2Dinitial fix
is not convergent
59
BAD_RANGE_CHITEST; range post-fix residuals chi-test failed
60
BAD_DOPPLER_CHITEST
doppler post-fix residuals chi-test failed
61
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.
