$GALA...
Use this special data input command to quickly update the MiLLennium-GLONASS GPSCard GLONASS
almanac tables following a system restart. It is generated from a MiLLennium-GLONASS GPSCard GALA log
and is accepted as the following format:
$GALA,993,151144.24,993,114250.25,3,21,1,3.004,3.12000,4.37933539E-002,2.68745422E-003,
-2.9000,-2.6003,4.88281250E-004,-2.3651123E-004*01
...
(one record for each valid satellite)

$IONA...
Use this special data input command to quickly update the GPSCard ionospheric corrections tables following a
system restart (always appended to $ALMA records unless intentionally stripped). This data will ensure that the
initial position solutions computed by the GPSCard are as accurate as possible. It is generated from a GPSCard
ALMA log and is accepted by any GPSCard as the following format:
$IONA,1.0244548320770265E-008,1.4901161193847656E-008,-5.960464477539061E-008,
-1.192092895507812E-007,8.8064000000004,3.2768000000004,-1.966080000005,
-1.966080000005*02
$UTCA...
Use this special data input command to quickly update the GPSCard Universal Time Coordinated (UTC)
parameters following a system restart (always appended to $ALMA records unless intentionally stripped).
The UTC data is required before the GPSCard can accurately compute UTC time. If not input with $UTCA, it may
take up to 12.5 minutes after a reset for the GPSCard to receive current UTCA data.
In order to comply with NMEA standards (see NMEA, Page 38 or refer to the References section of the
MiLLennium Command Descriptions Manual), the MiLLennium-GLONASS GPSCard will null NMEA log data
fields until valid UTC parameters are collected or injected by the $UTCA input command. This command is
generated from a MiLLennium-GLONASS GPSCard ALMA log and is accepted as the following format:
$UTCA,-1.769512891769409E-008,-1.776356839400250E-015,552960,744,755,9,10,5*03
