8. SV: The GPS or WAAS satellite number assigned to that particular channel. The valid GPS
PRN range is 1-32. The valid WAAS PRN range is 120-138.
9. State: The NCT proprietary satellite tracking value assigned to each satellite tracked that
indicates the type of tracking mode the satellite is in. This value ranges between 0 and 7, with
7 being optimal for GPS performance. Lower values indicate that the satellite is not available
for use. This may be due to lack of dGPS corrections, cycle slips, acquisition process, etc.
10. Elevation: The vertical angle of the satellite off the horizon ranging from 0 degrees to a
zenith of 90 degrees.
11. Azimuth: The horizontal angle of the satellite relative to the receiver position in reference to
North ranging from 0 (360) to 359 degrees.
12. CA: The L1 signal-to-noise value, which will vary depending on satellite elevation and any
obstructions between the satellites and the receiver. Optimal performance range for L1 C/N0
is 46dB to 52dB, although higher and lower values can be noted. A value > 50 is typical of a
satellite with 50º elevation or higher and a clear view of the sky.
13. P2: Not applicable to the SF-2110.
14. IODC: Issue of Data Clock. Indicates the issue number of the data as provided from the
GPS satellite in accordance with ICD-200C.
15. dGPS Age: The age of the current aided navigation correction. This value changes
depending on the correction source, and the correction interval.
16. Status: Not applicable to SF-2110
17. Last: Shows the MM:DD:YYYY and HH:MM:SS of the last 0x86 message update.
