GSM GPRS GPS Based Tracking Solutions

Overview:

It is perfectly suitable for applications that need location acquirement of remote objects. Hence you can track remote objects like trucks, cars, buses, ships and more quickly and easily. With this you can track the exact location of the vehicle using the particular software platform. The device ensures up-to-date status monitoring and delivery of the location/alarm messages to the end user’s registered mobile immediately. Location/status information is relayed through a hosted server, which allows for anywhere access logging as well as multi – user registered access.

Features:

Inbuilt GPS module provides accurate location information.
It is enabled with GPS, GSM and GPRS technologies.
GSM, uses GPRS to communicate with the server over IP networks.
