A: Space vehicle identification number.

B: The period when the satellite was in view. Each of these measurement blocks is a series of
measurements longer than 60 minutes, containing no breaks of more than 60 seconds.


C: Time at the start of the block (UTC).

D: Time at the end of the block (UTC).

E: Number of 1 second pseudorange measurements in the block.

F: Average value of UTC(MSL) minus GPS satellite time during the block
   (A constant offset over the course of a day is to be expected).

G: Average value of UTC(MSL) minus space vehicle time during the block, in nanoseconds.

H: Standard deviation of G during the block, in nanoseconds.

I: Number of measurements more than 4 standard deviations from the average.

J: Number of measurements more than 500 ns from the average.

K: Number of non-zero health flags in the block.
