RUTM59 GPS

The information in this page is updated in accordance with firmware version RUTM_R_00.07.11.3.

Summary

The Global Positioning System (GPS) is a space-based radionavigation system. This page is an overview of the GPS service in RUTM59 devices.

General

The General is used to enable the GPS service and the support for different types satellites. Once you turn on GPS, you can check the Map page in order to see if the device has obtained a GPS fix. It is very important to attach the GPS antenna on the device and place it outside (not inside of a building). The device will not be likely to obtain a GPS fix otherwise.

The figure below is an example of the General page and the table below provides information on the fields contained in that page:

Field	Value	Description
Enabled	off | on; default: off	Turns the GPS service on or off.
DPO enabled	off | on; default: off	Enable dynamic power optimization (requires modem reboot). This function is not supported on devices with Meig modems or Quectel BG95 modem
Galileo NMEA support*	off | on; default: off	Turns support for Galileo satellites on or off.
Glonass NMEA support*	off | on; default: off	Turns support for Glonass satellites on or off.
BeiDou NMEA support*	off | on; default: off	Turns support for BeiDou satellites on or off.

*Changing these options requires a modem reboot. Therefore, if you make changes to these options and save them, the device will lose cellular connectivity for about 30 seconds.

Map

The Map page displays the device's current coordinates and position on the map. To see the device's location on the map, make sure to attach the GPS antenna on the device and enable GPS in the General page.

The figure below is an example of the Map page:

NMEA

The NMEA page is used to configure settings related to NMEA sentence collecting and forwarding.

NMEA forwarding

---

The NMEA forwarding section is used to configure and enable NMEA forwarding. The figure below is an example of the NMEA forwarding section and the table below provides information on the fields contained in that section:

Field	Value	Description
Enabled	off | on; default: off	Turns NMEA forwarding on or off.
Hostname	ip | host; default: none	IP address or hostname of the server to which NMEA data will be forwarded.
Protocol	TCP | UDP; default: TCP	Protocol that will be used to send NMEA data.
Port	integer [0..65535]; default: 8500	Port number off the server to which NMEA data will be forwarded.
Contain connection	off | on; default: off	Contains active session with the remote server if turned on.
Select prefix	Custom | None |Serial | Mac address | IMEI; default: None	Prefix is added to the NMEA sentence before it is transmitted.

Hosts status

---

This section displays hosts status information.

NMEA forwarding cache

---

The device caches NMEA forwarding information if NMEA forwarding is enabled. This section is used to select the memory type where the cache will be stored and the maximum amount of data that will be saved:

Field	Value	Description
Save cache in	RAM Memory | FLASH Memory; default: RAM Memory	Selects which type of memory will be used for storing NMEA forwarding cache.
Maximum sentences	integer; default: 5000	Maximum amount of NMEA sentences that will be saved in the cache before older entries are deleted and replaced by new ones.
File	filepath; default: none	Location of the file where NMEA forwarding cache information will be stored. This field becomes visible only when the selected memory type is "flash".

NMEA serial forwarding

---

This section is used to configure NMEA serial forwarding settings:

Field	Value	Description
Enabled	off | on; default: off	Turns NMEA serial forwarding on or off.
Select prefix	none | Serial | Mac address | IMEI; default: none	Prefix is added to the NMEA sentence before it is transmitted. Example: 0012345567_$GPRMC....

NMEA serial ports

This section displays NMEA serial forwarding port instances currently existing on the router. To add a new serial port instance, press 'Add' button:

You will then be taken to the NMEA serial port configuration page:

Field	Value	Description
Enable	off | on; default: off	Enable service.
Name	string; default: none	Name of serial port.
Device	USB RS232 interface; default: USB RS232 interface	Specifies which serial port will be used for serial communication.
Baud rate (USB)	integer [300..4000000]; default:9600	Data rate for serial data transmission (in bits per second (bps)).
Data bits	8; default: 8	Number of data bits for each character.
Stop bits	1 | 2; default: 1	Stop bits sent at the end of every character allow the receiving signal hardware to detect the end of a character and to resynchronise with the character stream. Electronic devices usually use one stop bit. Two stop bits are required if slow electromechanical devices are used.
Parity	None | Odd | Even | Mark | Space; default: None	In serial transmission, parity is a method of detecting errors. An extra data bit is sent with each data character, arranged so that the number of 1 bits in each character, including the parity bit, is always odd or always even. If a byte is received with the wrong number of 1s, then it must have been corrupted. However, an even number of errors can pass the parity check. None (N) - no parity method is used. Odd (O) - the parity bit is set so that the number of "logical ones (1s)" has to be odd. Even (E) - the parity bit is set so that the number of "logical ones (1s)" has to be even.
Flow control	None; default: None	In many circumstances a transmitter might be able to send data faster than the receiver is able to process it. To cope with this, serial lines often incorporate a "handshaking" method, usually distinguished between hardware and software handshaking.

Different priority settings add different flags to event packets, so they can be displayed differently in the receiving system. The device sends data of higher priority first. Priority levels from highest to lowest are as follows: Security Panic High Low
Collect period	integer [1..999999]; default: 10	How often (in seconds) data will be collected.

Field	Value	Description
Signal	off | on; default: off	Includes GSM signal strength information in the GPS data sent to server.
Din1	off | on; default: off	Includes Din1 status information in the GPS data sent to server.

Note: TAVL signal rule indicates signal strength (RSSI) and returns numerical value according to this table:

No. of Value	Signal strength
0	No signal
1	<= -97 dBm
2	-82 dBm to -97 dBm
3	-67 dBm to -82 dBm
4	-52 dBm to -67 dBm

AVL I/O

The AVL I/O tab provides you with the possibility to configure input rules.

Input Rules

GPS Geofencing

A geofence is a virtually defined boundary for a real-world geographic area. The GPS Geofencing page provides you with the possibility to set this custom area and apply rules that will inform you when the device leaves or enters the geofence.

To create a new geofence area, enter a custom name for it and click the 'Add' button. A new geofence area configuration with the given name should appear in the "Geofencing" list. Click the button that looks like a pencil next to it to begin editing.

The figure below is an example of GPS Geofencing configuration and the table below provides information related to that configuration:

Field	Value	Description

Longitude (X)	degrees [-180.000000..180.000000]; default: 0.000000	East-west position of a point on the Earth's surface. Combining this and the Latitude information will produce a point on the world map that will serve as the center of the geofence area.
Latitude (Y)	degrees [-90.000000..90.000000]; default: 0.000000	North-south position of a point on the Earth's surface. Combining this and the Longitude information will produce a point on the world map that will serve as the center of the geofence area.
