lon Antenna longitude. The format is dd:mm:ss.ss.
height Antenna height; ±10,000.0 meters.
AVG n Number (n) of averages for the calculated position fixes.
Range is 10 to 1,000. Setting this places the unit into
survey mode. The frequency control is placed into holdover
during survey mode.
AVAIL Shows the current satellite availability. A table is generated
with the following information:
SV Satellite PN code ID.
Elev Current elevation above the horizon of the satellite, in
degrees.
Azmth Azimuth of the satellite, in degrees.
Hlth Health of the satellite, either H or U. Unhealthy can also
mean that the user has set the receiver to ignore the
satellite.
PDOP Sets the current Position Dilution of Precision or pdop mask
(1 through 10). Pdop is a measurement that indicates the
geometry of the GPS satellites that the SSU-2000 is
tracking. Lower values indicate better geometry.
TDATA Provides tracking information for the engine. Available
options are:
ON Tracking data displays on that communications port.
OFF Tracking data does not display on that communications
port.
CLR No tracking data displays on any communications port.
Level 4 Same as Level 3 operation
Remarks
ELMASK Default values for the masks are 5 degrees for the
positioning mask and 10 degrees for time.
POS Only set the position if you know the accurate position. The
software automatically verifies the position on restart. The
unit averages 10 position fixes and compares them to the
fixed position.
Note: Only satellites that are above the current elevation mask are
shown.
