Not yet implemented in receiver firmware revision 3.34

Value Description

0Observations are good
1Bad satellite health is indicated by ephemeris data
2 Old ephemeris due to data not being updated during last 3 hour s
3Eccentric anomaly error during computation of the satellite’s position
4 True anomaly error during computation of the satellite’s position
5 Satellite coordinate error during computation of the satellite’s positio n
6 Elevation error due to the satellite being below the cutoff angle
7 Misclosure too large due to excessive gap between estimated and a ctual positions
8 No differential correction is available for this particular satellite
9 Ephemeris data for this satellite has not yet been received
10 Invalid IODE due to mismatch between differential stations
11 Locked Out: satellite is excluded by user (LOCKOUT command)
12 Low Power: satellite rejected due to low signal/noise ratio
13 L2 measurements are not currently used in the filter

Value Description

0 Velocity computed from differentially corrected carrier phase data
1 Velocity computed from differentially corrected Doppler data
2 Old velocity from differentially corrected phase or Doppler (higher la tency)
3 Velocity from single point computations
4 Old velocity from single point computations (higher latency)
5Invalid velocity
