Command: Get Satellite Masking Angle
Format: $PDME,7<cr><If>
Variables: None
Return: “$PDME,7,<maskang>”
Operation: Returns the angle below which satellites are ignored; returned value is in whole degrees for the current GPS Library.
Application: Informational; used with Set Mask Angle to establish and effective satellite horizon to eliminate multipath (reflected)
signals
Command: Set Satellite Masking Angle
Format: $PDME,8,f<cr><If>
Variables: f=0 to 90 degrees
Return: “$PDME,8,OK” if the command is accepted
Operation: Sets the angle below which satellites are ignored; decimal values may be entered but the GPS Library only accepts
whole numbers as of now.
Application: Valuable tool for eliminating multipath signals typically found in environments with a limited sky view and a lot of
reflected satellite signals, such as urban canyons.
Command: Initialize GPS Position and Time
Format: $PDME,9,n1,n2,n3,n4,n5,n6,n7,n8,n9<cr><If>
Variables: n1=Latitude in (whole) degrees
Return: “$PDME,9,OK” if the command is accepted
Operation: Sets the values used for the initial position calculations
Application: Valuable for a unit that has been moved while off; a faster TTFF can be achieved by preloading the position and
time information; must be issued immediately after a reset or startup to be most effective.
Command: NMEA Port Messaging Controls
Format: $PDME,10,n<cr><If>
Variables: n = 0,1, 2, 3,4 or 5
Return: “$PDME,10,OK” if command is accepted.
Operation: n=0,1 turns NMEA messages Off or On, respectively;
Application: Valuable for customizing the content selection on NMEA port.
n2=Longitude in (whole) degrees
n3=Altitude in (whole) meters
n4=Year (four digits)
n5=Month (1-12)
n6=Day(1-31)
n7=Hour(0-23)
n8=Min(0-59)
n9=Sec(0-59)
n=2,3 turns ECH messages Off or On, respectively, but if the NMEA messages are off, the n=2,3 has no effect.
n=3,4 turns Debug messages Off or On, respectively. When on, Debug info is directed to the NMEA port and regular
NMEA messages are disabled; Debug information remains on the Debug port. Disabling the Debug message returns
the NMEA port to normal messaging.
