PMD: Position Mode
$PASHS,PMD,d
Set position mode for minimum number of SVs required to compute a position fix,
where d = 0, 1, 2, or 3. The default is 0.
Example: Set min SVs required for position computation to 4
$PASHS,PMD,0 <enter>
POS: Set Antenna Position
$PASHS,POS,m1,c2,m3,c4,f5
Sets the position of the antenna used in differential base mode.
Example: Set antenna position

Table 6.32: PMD Parameter Table
Parameter Description
d = 0 minimum of 4 SVs needed (e.g., for 3-D)
d = 1 default, minimum of 3 SVs needed; with 3 SVs, altitude is held (2-D); with 4 or
more, altitude is not held (3-D)
d = 2 minimum of 3 SVs needed; altitude always held (always 2-D)
d = 3 minimum of 3 SVs needed; with 3 SVs, altitude is always held; with 4 SVs,
altitude is held only if HDOP is greater than HDOP mask (2-D), otherwise 3-D
