Chapter 6 Data Logs

6.3.6 RAWEPHEM Raw Ephemeris

This log contains the raw binary information for subframes one, two and three from a 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 is not generated unless all 10 words from all 3 frames have

passed parity.

Ephemeris data whose Time Of Ephemeris (TOE) is older than six hours is not shown.

Log Type: Asynch Message ID: 41
