 Receiver tab - Antenna Height
: This is entered as a "vertical" or "slant" height in the current job units. The slant
height is the distance from the base of the pole or from the “hub and tack” up to a mark or defined slant
measurement point on the edge of the antenna (See NGS for more details). The vertical height is measured plumb,
straight down from the base of the antenna (where it screws into the antenna).
 Receiver tab - Elevation Mask
: This specifies the cutoff vertical angle above the horizon. Any satellites below
this angle will be left out of calculations.
 Receiver tab - Log OBEN Data for Averaged RTK Readings:
This setting specifies that the software will log
the standard Thales OBEN file as specified by Thales during averaged readings.
 Ports tab - RTK Port
: You must select the data port on the GPS receiver that is connected to the radio modem.
The default setting is A. Changing this setting will change the internal setting of the receiver.
 Ports tab - Radio Type:
This allows the user to specify the various supported radios.
 Ports tab - Message Type
: You must specify the message type. For high precision centimeter RTK GPS, set this to
Ashtech (CPD). For USCG/RTCM DGPS sub-meter accuracy, set this to RTCM.
 Ports tab - Baud
: This setting allows you to change Pacific Crest radio baud settings through the receiver. The
default baud rate is 9600. (Note: If there are communication problems with either port A or B on the Ashtech
ZSurveyor receiver, turn off receiver and turn it back on with both keys depressed to reset receiver to factory
defaults.)
