MKTA/B Time of Mark Input
This log contains the time of the detected Mark Input pulse leading edge as detected at the Mark Input I/O port.
The resolution of this measurement is 49ns. Refer to the GPSCard Installation and Operating Manual Appendix
for the Mark Input pulse specifications.

2week GPS week number 653
3seconds Seconds into the week as measured from the receiver clock, coincident with the
time of electrical closure on the Mark Input port. 338214.773382376
4offset Receiver clock offset, in seconds. A positive offset implies that the receiver clock
is ahead of GPS Time. To derive GPS time, use the following formula:
GPS time = receiver time - (offset)
0.000504070
5offset std Standard deviation of receiver clock offset, i n seconds 0.000000013
6utc offset This field represents the offset of GPS time from UTC time, computed using
almanac parameters. To reconstruct UTC time, algebraically subtract this
correction from field 3 above (GPS seconds).
UTC time = GPS time - (utc offset)
-8.000000000

the model is in the process of stabilization 0
