Connection of Galileosky Base Block Hard Wi-Fi

General Information

Galileosky tracking devices determine mobile object location, recording the time and route as

points with geographical coordinates and send the data to the server to be further processed

and displayed at the traffic controller panel.

In addition, a number of other vehicle parameters are recorded: the state of analog and

discrete inputs of the tracking device and the state of digital interfaces.

The tracking devices can be used in any vehicle.

Technical and functional capabilities of the tracking device allow to carry out:

real-time monitoring of vehicle location;



monitoring of vehicle parameters via discrete-analog inputs or RS485, RS232 digital



interfaces or CAN-bus;

recording of monitoring data to internal nonvolatile flash-memory, in case of no GSM



communication;

detailed turning drawing without extra points on a straight part of the road;



remote configuring via SMS or GPRS;



remote software updating of the tracking device via GPRS;



securing mobile or stationary objects.



Hard Wi-Fi modification is intended to reduce costs on GPRS-communication and increase

speed of data transmission. The examples of implementation of such modification are the

following:

use of the tracking device at stationary objects with Wi-Fi access to the Internet;



use of the tracking device in vehicles that are often located in the areas with poor GSM



cellular communication or its complete absence. In such a case, telemetrical data are

saved into the tracking device's memory, and uploaded via Wi-Fi to the server, when the

vehicle enters the area with an authorized Wi-Fi network.

The algorithm of data transmission by the tracking device is the following:

as soon as the tracking device enters the area with Wi-Fi network, it establishes connection



with Wi-Fi access point and starts transmitting telemetrical data via this access point to the

monitoring server. In such a case, GSM-module cuts off.

In case connection with Wi-Fi access point is broken, the tracking device activates GSM-



module, establishes GPRS connection and continues transmitting telemetrical data to the

monitoring server. In addition, the tracking device is constantly searching for Wi-Fi

network.
