Legend
GPS PRNThe unique pseudo random noise (PRN) code (1 to 32) used to identify each satellite. If no satellite is assigned to a given PRN code, then no data are shown.
Minutes
(In-View)		The number of minutes when the satellite was visible. During this period, the time difference between the satellite clock and SIMT(INCP) is measured every second, and 10 minute averages are stored. Since data is recorded in 10 minute segments, the values are even multiples of 10 minutes.
Mean Time
Offset		The mean time offset (nanoseconds) of the 10-minute averages recorded from each satellite.
RangeThe difference between the maximum and minimum time offset values (nanoseconds).
Time
Deviation		The time deviation (TDEV) of the 10-minute averages (nanoseconds).
Frequency
Offset		The estimated frequency offset of the satellite clock with respect to SIMT(INCP). This estimate is obtained by fitting a least squares line to all of the recorded data.
Confidence
Level (r)		The confidence level of the estimated frequency offset. The confidence level is the correlation coefficient (r) of the least squares line fitted to the data.
View
Track		Clicking on the View link displays a plot of data from the selected satellite. The number of previous days shown equals the number of previous days shown on this page, up to a maximum of 30 days.
