<P>The format of the epoch / satellite line in the observation
record part of the RINEX Observation files has only been
defined for up to 12 satellites per epoch. We explicitly
define now the format of the continuation lines, see table
A2.</P>
<P>8.2 RINEX Navigation Files for GLONASS</P>
<P>As the GLONASS navigation message differs in contents from
the GPS message too much, a special GLONASS navigation message
file format has been defined.</P>
<P>The header section and the first data record (epoch,
satellite clock information) is similar to the GPS navigation
file. The following records contain the satellite position,
velocity and acceleration, the clock and frequency biases as
well as auxiliary information as health, satellite frequency
(channel), age of the information.</P>
<P>*** In order to use the same sign conventions for the time
and frequency bias as in the GPS navigation files, the
broadcast GLONASS values are multiplied by -1.</P>
<P>The time tags in the GLONASS navigation files are given in
UTC (i.e. _not_Moscow time or GPS time).</P>
<P>Filenaming convention: See above.</P>
