DEVICE DESCRIPTION:
The NovAtel GPSCard
PC cards rather than as stand alone devices, allowing for the unit to be installed
internally in a host desktop computer. Instead of relying on a serial connection (and the
required cabling) to communicate with the computer, GPSCards utilize the PC ISA bus.
GPSCards are also configured with dual RS232 ports allowing for input and output of
data via serial connections, if so desired. These 2 DB9 male connectors allow you to
receive differential corrections from a DGPS receiver or output data to another
computer, with baud rates varying from 300 to 115,200 bps.
TM
The GPSCard
PC Series are 12 channel parallel tracking, C/A code GPS receivers,
utilizing the L1 (1575.42 MHz) frequency GPS signal. The NovAtel custom proprietary
correlater chip, combined with a high performance 20 MHz 32-bit CPU is capable of
measuring satellite code and carrier phase data to compute up to 10 position solutions
per second. Positional data (stand alone or differentially corrected) can be output at a
rate of up to 20 times per second.
For use with WinFrog, these cards are set to output raw Pseudorange and Ephemeris
data as well as internally calculated, differentially corrected positions. WinFrog's
optional GPS Calculations extension module can combine the raw Pseudorange and
Ephemeris data with up to 5 differential GPS corrections to provide a Multi-Ref position
(See chapter 14 of the WinFrog Users Guide for more details).
The internally calculated position can utilize differential corrections received via the
serial ports or the PC ISA bus.
The GPSCards must be correctly installed and configured before they can be used with
WinFrog. This involves that you follow specific installation procedure, not just simply
installing the card into the computer. These instructions are listed below in the section
entitled Driver Installation.
This device can provide time synchronization using $--ZDA. See chapter 8.

Summary of Contents for Novatel GPSCard PC Series

  • Page 1 The GPSCard PC Series are 12 channel parallel tracking, C/A code GPS receivers, utilizing the L1 (1575.42 MHz) frequency GPS signal. The NovAtel custom proprietary correlater chip, combined with a high performance 20 MHz 32-bit CPU is capable of measuring satellite code and carrier phase data to compute up to 10 position solutions per second.
  • Page 2 DEVICE CONFIGURATION INSTRUCTIONS WINFROG I/O DEVICES > EDIT I/O: The NovAtel CON (console) device is added to WinFrog from the GPS device group. The Novatel PC Card dialog box (shown below) appears when the NovAtel CON (console) device is selected. Within this dialog are various configuration options. The settings are dependant on the GPSCard that has been installed in the PC.
  • Page 3 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.
  • Page 4 Undulation Model: The Undulation Model can be set to the Internal Table, which uses the NovAtel’s internal (OSU) geoid model, or Input Value in which case a specific Ellipsoid separation value can be input. This Ellipsoid separation value is used to calculate...
  • Page 5 WINFROG VEHICLE > CONFIGURE VEHICLE DEVICES > DEVICE DATA ITEM > EDIT: Adding a NovAtel CONSOLE device to WinFrog provides you with three separate data items: Position, Pseudorange and Ephemeris. The GPS, CONSOLE, POSITION data item refers to the position data calculated and output by the GPSCard. The GPS, CONSOLE, PSEUDORANGE and GPS, CONSOLE, EPHEMERIS data items provide WinFrog with only raw measurement data.
  • Page 6 If On is selected, a labeled square will be made visible in the Graphics and Bird’s Eye displays, depicting the raw (unfiltered) location of the GPS antenna. This provides a means of comparing raw and filtered positions between different sources. WinFrog User’s Guide - Appendix C – GPS/NovAtel Con Page 6 of 22...
