GPS tracking systems basic types of systems:

GPS receivers that receive position data from the Global Positioning System satellites. They also have SIM chips (wireless telephone chips) that transmit the GPS position data via a digital cellular network. The information is ultimately sent to a server where the GPS data information is received. Typically, these servers integrate the received GPS data, along with mapping software to show you a devices position in addition to other information.

The benefits of a GSM network based system:

The cost of data is relatively inexpensive and service on major network providers is reliable. When you operate your vehicles in major metropolitan areas or along most major roads and highways across the world you would probably want to consider one of these systems.

Information is limited to areas of GSM coverage. If you operate a device like this in a remote area, you will be unable to track/manage your vehicles, until they returned into an area with a GSM signal.

SekurTrack™ is a Data logger and a tracking system in the case of no GSM coverage SekurTrack™ will log all the events and transmit the date once coverage is available.

Satellite Based GPS Tracking Systems:

These GPS devices receive GPS position data from the Global Positioning System satellites. GPS information is transmitted back via satellite by the device. Satellite Devices: Communication is one way - the device transmits received information outwards bound. It is not possible to remotely communicate with the device. i.e. The GPS Locator is a simplex device, it is pre-programmed to report its position, but you cannot locate this device on DEMAND.

Duplex Satellite Devices:

Communication is two way - the device will transmit information and can also receive information i.e. One can locate on DEMAND in near real-time a device that is configured on a duplex satellite network. Messaging is also possible on a duplex system, for example, a fleet manager who needs to communicate with a driver, and vice versa.

The Benefits Of A Satellite Based System:

Coverage is worldwide and there is no dependency on GSM networks for the device to work.

The Drawbacks of a Satellite Based System:

Monthly costs are generally higher than cellular based systems, since transmissions are all done between satellites and data costs are relatively higher.
