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