Next PRN offset = 32 + (obs*32) where obs varies form 0 to (obs-1)

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
