Options:
-t=<level> - turn trace level (1, 2 or 0 - turn trace off)
-a[=(0:1)] - turn the power on the antenna amplifier
-p=<port> - set TCP port for service (2323 by default)
-s=<baudrate|0> - set baud rate for GPS NMEA port (0 - set 115200)
-c=<con_mask> - set current constellation:
1 - GPS
2 - GLONASS
3 - GPS+GLONASS
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 |

| -t=<level> | Configure event logging - "2" – to log all the NMEA-messages from the GPS/GLONASS-receiver
- "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.
- "0" – event logging is off
| | -a[=(0:1)] | Enables / disables the power supply to the antenna amplifier (if one is available): - "1" - to enable the power supply (is used by default, if the value is not specified)
- "0" - to disable the power supply
| -p=<port> | Sets the TCP port for receiving debugging information. 2323 is set by default. | -s=<baudrate|0> | Sets the baud rate of the GPS NMEA port. - "baudrate" - the rate value.
- "0" - sets the value to 115200.
| -c=<con_mask> | Satellite navigation system selection: - "1" - GPS
- "2" - GLONASS
- "3" - GPS+GLONASS

- "Satellites" - quantity of currently visible satellites
- "LAT/LONG" - geographical coordinates of the receiver in degrees:
- "LAT" - latitude from -90.0000000° to +90.0000000°
- "LONG" (longitude) - longitude from -180.0000000° to +180.00000°
- "Altitude" - altitude in meters
- "HDOP" - horizontal dilution of precision
| Warning |
|---|
| It is recommended to use values of “HDOP” parameter up to 1.5 for reliable global timing synchronization. |
- FIX - NO FIX|2D|3D, <unknown>|GPS|GLONASS|GPS+GLONASS – the current position-fix status in the following view: <current fix mode>, <system>. The following values of <current fix mode> are available:
- "NO FIX" - coordinates are not fixed
- "2D" – only latitude and longitude are fixed
- "3D" – latitude, longitude and altitude are fixed.
The following values of <system> (currently used GNSS) are available: The next block of information is the statistics (to obtain these data without information about status of GPS/GLONASS-receiver you can use "gps stat" command instead). - "Total GPS time" — total time of GPS utility operation since it was started by "gps start" command
- "Total nonvalid time" – total time during which the information about coordinates was unavailable
- "Number of losses" — quantity of cases when the information about coordinates had become unavailable
- "Now coordinates are valid last …" - time of GPS utility operation since last coordinates discovering
- "Satellites histogram" - the histogram of visible satellites quantity
- "SATmin" и "SATmax" — minimum and maximum of visible satellites respectively (since the last time you cleared the statistics)
| console | Displays an information in GPS NMEA format, is used for debugging. The GPS/GLONASS-receiver should be stopped | | tcp | An information in the GPS NMEA format is transmitted to the TCP port assigned earlier by the "-p" parameter. The GPS/GLONASS-receiver should be stopped | | stat | View GPS/GLONASS-receiver operation statistics(without the status information) | | clear | Reset the statistics data |

Please note, that "tcp" and "console" commands and "-p" and "-s" options are used for diagnostics and debugging on emergency by specialists only. |
