 MiLLennium GPSCard Software Version 4.50 Command Descriptions Manual Rev 1

This log contains the raw Binary information for subframes one, two and three from the satellite with the parity
information removed. Each subframe is 240 bits long (10 words - 24 bits each) and the log contains a total 720 bits
(90 bytes) of information (240 bits x 3 subframes). This information is preceded by the 

PRN

 number of the satellite

from which it originated. This message will not be generated unless all 10 words from all 3 frames have passed
parity.

Ephemeris data whose toe (time of ephemeris) is older than six hours will not be shown.
