Total Bytes: 37
For a given channel expecting more than one block of data, when one of them is not yet available,
the warning flag is set to 7 and the rest of the block is zeroed out.
This message is output for those satellites with elevation equal to or greater than the elevation
mask, and only if the number of locked satellites is equal to or greater than the minimum satellite
mask.
MCM: Missile Application Condensed Measurement
Record (MACM)
This message optimizes the data output and data transmission in high dynamic
applications requiring high speed data output with communications bandwidth
limitations.
$PASHS,RAW,MCM,c1,s2,[f3]
This command enables or disables the missile application condensed
measurement record, where c1 is the output port (A, B, or C) for the response
message. s2 is ON (enable) or OFF (disable), and f3 is the optional message
interval in seconds ranging from 0.05 to 999 seconds. If the command is set without
an interval, the G12 uses the period set by the $PASHS,RCI command If the
$PASHS,RCI command is issued after this message period has been set, the period
resets to the RCI setting.
Examples
Enter the following command to enable the missile application condensed
measurement record through port A at the current RCI setting:
$PASHS,RAW,MCM,A,ON
200
Bytes
4 32 bits where 31-24 are the smooth_count, unsigned, and
normalized, representing the amount of smoothing specified in the
$PASHS,SMI command:
• 0 - Unsmoothed
• 1 - Least smoothed
• 255 - Most smoothed
Bits 23-0 are smooth_corr, where bit 23 (MSB) is the sign and the
LSBs (22-0) are the magnitude of correction in centimeters
1 Checksum, a bytewise exclusive OR (XOR) of all bytes from
sequence_tag (just after header) to the byte before checksum
