Code Block
languagejava

  Options:
    -t=<level>  - turn trace level (1, 2 or 0 - turn trace off)
 	-i=<int>    - set integrator time constant in seconds
    -a[=(0:1)]  - turn the power on the antenna amplifier
    	-r[=(0:1)]  - set reset signal 
    -p=<port>   - set TCP port for service (2323 by default)
    -s=<baudrate|0>  - set baud rate for GPS NMEA port (0 - set 115200)
  Command:
    start       		- start GPS service
    stop        - stop  GPS service
    coordinates - show  GPS coordinates
    console     - map GPS NMEA port to stdin/stdout
    tcp         - map GPS NMEA port to TCP service 
    stat        - show GPS statistics 
    clear       - clear GPS statistics

Options

If you need to configure event logging, you can choose the required trace level, using the following option:
Center
Scroll Title
titleTable - Command "gps" options
OptionDescription
-t=<level>

The following trace levels are available (from maximum to minimum details):

Level 2
  • Configure event logging
    • "2" – to log all the NMEA-messages from the GPS/GLONASS-receiver
.
Level
    • "1" – to log only the messages about discovering / loss of the GPS/GLONASS-receiver, about the changing of the quantity of detected satellites or about substantial changes of coordinates, etc.
Level
    • "0" – event logging is off
.If you need to enable
-a[=(0:1)]
  • Enable / disable the power supply to the antenna amplifier (if one is available)
, you can set the corresponding value, using the following option
  • :
    -a[=<value>]<value>=1 –
      • "1" - to enable the power supply (is used by default, if the value is not specified)
    <value>=
      • "0
    –
      • " - to disable the power supply

    Commands

    To start the operation of GPS service, use the following command:

    • start

    To stop the operation of GPS service, use the following command:

    • stop

    If you need to view statistics of GPS/GLONASS-receiver operation (without the status information), use the following command:

    • stat

    In order to clear the statistics, use the following command:

    • clear
