If problems persist, refer to the Configuration Details section below for information on
setting up the GPSCard and installing the required files.
WINFROG I/O DEVICES > CONFIGURE DEVICE:
This device must be configured at the I/O Device window level. In the I/O Devices
window, click the device name to select it, then right-click and select Configure Device.
The GPSSET Configuration dialog box appears, as seen below. This configuration
dialog sets the internal calculation parameters of the NovAtel GPSCard.
Position:
An approximate initial position must be entered to provide the position calculations
with a reasonable starting point. This position should be within approximately 5
minutes in both Latitude and Longitude. Ensure that the "quadrant" signifiers are
correct: N/S or E/W.
Antenna Height:
Set the antenna height mode to one of the two provided options:
Calculated – Along with Latitude and Longitude, the NovAtel GPSCard will
calculate the GPS antenna Geoidal Height (Mean Sea Level). A minimum of four
satellites must be tracked in order to calculate both horizontal position and
height.
Fixed - Fixes the GPS antenna height to the Geoidal Height (Mean Sea Level)
value entered in the provided entry box. In this mode, the NovAtel GPScard is
able to calculate horizontal positions using a minimum of three satellites.
