Value Description
0 Observations are good
1 Bad satellite health is indicated by ephemeris data
2 Old ephemeris due to data not being updated during last 3 hours
3 Eccentric 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 position
6 Elevation error due to the satellite being below the cutoff angle
7 Misclosure too large due to excessive gap between estimated and actual 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
