Value Description
0Observations are good
1Bad satellite health is indicated by ephemeris data
2Old ephemeris due to data not being updated during last 3 hours
3Eccentric anomaly error during computation of the satellite ’s position
4True anomaly error during computation of the satellite’s po sition
5Satellite coordinate error during computation of the satelli te’s position
6Elevation error due to the satellite being below the cutoff angle
7Misclosure too large due to excessive gap between estim ated and actual positions
8No differential correction is available for this particular sate llite
9Ephemeris 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 com mand)
12 Low Power: satellite rejected due to low signal/noise ratio
13 L2 measurements are not currently used in the filter
Higher numbers are reserved for future use
Value Description
0 Velocity computed from differentially correct ed carrier phase data
1 Velocity computed from differentially correct ed Doppler data
2Old velocity from differentially corrected phase or Dopple r (higher latency)
3Velocity from single point computations
4Old velocity from single point computations (higher latenc y)
5Invalid velocity
Higher numbers are reserved for future use
