4 Operation
C:\GPS>
4.
The GPSCard is now initialized with the contents of the BOOT1.TXT command file, and logging is
directed from the GPSCard's COM2 port to the remote terminal.
4.3.3 MICROSOFT WINDOWS 3.1 OR HIGHER
As any text editor or communications program can be used for these purposes, the use of Windows 95 is described
only as an illustration. The following example shows how Windows 95 accessory programs Notepad and
HyperTerminal can be used to create a hypothetical waypoint navigation boot-file on a PC, and send it to the
GPSCard. It is assumed that the PC's serial port COM1 is connected to the GPSCard's COM1 port, and that a
remote terminal is connected to the GPSCard's COM2 port.
Example:
1.
Open Notepad and type in the following command text:
setnav 51.111 -114.039 51.555 -114.666 0 start stop
magvar -21
log com1 posa ontime 15
log com1 spha ontime 15
log com1 nava ontime 15
log com2 gprmb ontime 15 5
log com2 gpvtg ontime 15 5
log com2 rcca ontime 60
2.
Save this with a convenient file name (e.g. C:\GPS\BOOTNAV1.TXT) and exit Notepad.
3.
Ensure that the HyperTerminal settings are correctly set up to agree with the MiLLennium-GLONASS
GPSCard communications protocol; these settings can be saved (e.g. C:\GPS\OEMSETUP.HT) for use
in future sessions. You may wish to use XON / XOFF handshaking to prevent loss of data.
4.
From the Transfer menu, use the Send text file selection to locate this file to be sent to the MiLLennium-
GLONASS GPSCard. Once you double-click on the file or select Open, HyperTerminal will send the file
to the MiLLennium-GLONASS GPSCard.
The above example initializes the GPSCard with origin and destination waypoint coordinates and sets the magnetic
variation correction to -21 degrees. The POSA, SPHA, and NAVA logs have been set to output from the GPSCard
COM1 port at intervals of once every 15 seconds, whereas the GPRMB and GPVTG NMEA (see NMEA, Page 38)
logs have been set to be logged out of the GPSCard COM2 port at intervals of 15 seconds and offset by five
seconds. The RCCA log has been set to output every 60 seconds from the GPSCard's COM2 port.
Before operating the GPSCard for the first time, ensure that you have followed the installation instructions of
Chapter 3, and if you have a ProPak II enclosure or PowerPak II enclosure, have reviewed Appendix E, Page 59,
or Appendix F, Page 73, respectively. The following instructions are based on a configuration such as that shown
in Figure 3.1, Page 17. It is assumed that a personal computer is used during the initial operation and testing for
greater ease and versatility.
4.4 COMMANDS COMMON TO ALL GPSCARDS
The GPSCard is capable of responding to over 50 different input commands. You will find that once you become
familiar with these commands, the GPSCard offers a wide range in operational flexibility. All commands are
accepted through the COM1 and COM2 serial ports.
4.4.1 COMMANDS SPECIFIC TO MILLENNIUM-GLONASS GPSCARD
The MiLLennium-GLONASS GPSCard accepts two GLONASS specific commands:
•
DGLOTIMEOUT (see Page 82)
•
PZ90TOWGS84 (see Page 82)
For a listing of commands common to all GPSCards, with the exception of the GLONASS specific commands,
refer to the MiLLennium Command Descriptions Manual. For details on GLONASS specific commands, see Page
