Manual:System/GPS
Summary
Sub-menu: /system gps
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
Parameters:
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 init-string: 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

Troubleshooting
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"
