FIX: Fixed Altitude Mode
$PASHS,FIX,d1
This command sets the fixed altitude mode. It is typically used when the receiver
is in 2-D position mode or when there are not enough visible satellites to compute
a 3-D position; d1 can be 0 or 1. You can view the current setting for fixed altitude
mode with the
$PASHQ,PAR command and checking the FIX field.
• Fixed Altitude Mode 0
The most recently recorded antenna altitude is used. The altitude value is
taken either from the altitude entered through the
$PASHS,ALT command
or from the last altitude computed in which the VDOP value is lower than
the value entered for the VDOP mask
• Fixed Altitude Mode 1
Only the most recent altitude value entered through the $PASHS,ALT
command is used.
Example
Enter the following command to set the DG16 in fixed altitude mode 1:
$PASHS,FIX,1
FUM: Fix UTM Zone
$PASHS,FUM,c1
This command enables/disables the fixing of the UTM zone, where c1 is Y (enable)
or N (disable). The default is N. This command is typically enabled when the user
is near a UTM boundary and wants to avoid the coordinate shift that occurs when
