Standards: GPS, NMEA 0183, Simple Text Output Protocol

Global Positioning System (GPS) is used for determining precise location of a GPS receiver.

Configuration Properties

Property Description
enabled (yes | no; Default: no) Whether GPS is enabled
port (string; Default: ) Name of the USB/Serial port where GPS receiver is connected
channel (integer [0..4294967295]; Default: 0) Port channel used by device
init-channel (integer [0..4294967295]; Default: ) Channel for init-string execution
init-string (string; Default: ) AT init string for GPS initialization
set-system-time (yes | no; Default: no) Whether to set router's date and time to one received from GPS.

Monitoring Status

Command: /system gps monitor

This command is used for monitoring the data received from a GPS receiver


Property Description
date-and-time (date) Date and time received from GPS
latitude (none | string) Latitude in DM (Degrees Minute decimal) format
longitude (none | string) Longitude in DM (Degrees Minute decimal) format
speed (none | string) Current moving speed of the GPS unit
bearing (none | string) The compass direction toward which a GPS is moving
valid (yes | no)
satellites (integer) Number of satellites seen by the device.

Note: The time is not stratum 1 as CableFree device devices do not have PPS implemented

Basic examples

Adjust port settings specific for your device

[admin@CableFree] /port> set 0 baud-rate=4800 parity=odd
[admin@CableFree] /port> print detail 
Flags: I - inactive 
 0   name="usb1" used-by="GPS" channels=1 baud-rate=4800 data-bits=8 parity=odd stop-bits=1 flow-control=none

Enable GPS

[admin@CableFree] /system gps> set enable=yes port=usb1
[admin@CableFree] /system gps> print 
          enabled: yes
             port: usb1
          channel: 0
     init-channel: 0
  set-system-time: no

Monitor status

[admin@CableFree] /system gps> monitor  
  date-and-time: jul/02/2015 14:36:08
             latitude: N 56 57' 32.262''
            longitude: E 24 9' 7.262''
             altitude: 36.700001m
                speed: 0.000000 km/h
  destination-bearing: none
         true-bearing: 0.000000 deg. True
     magnetic-bearing: 0.000000 deg. Mag
                valid: yes
           satellites: 7

Note that sometimes in order to make GPS module recognize under RouteOS you need to change the baud-rate setting in the '/port' menu.

On some modems with GPS support you need to send multiple inits commands for the continues GPS monitoring, for example, for huawei card you need to send such init strin to get continuous monitoring "AT^WPDST=1,AT^WPDGP"
