A key part of the vehicle tracking device is the GPS receiver/antenna. There are multiple GPS satellites that are developed and maintained by the US military, orbiting the Earth. These satellites are continually transmitting signals which are being received by the range of commercial devices that utilise this technology such as satellite navigation aids and of course tracking systems.

A GPS vehicle tracking device uses the signals received from multiple satellites to calculate its current global location as well as its direction of travel and speed. This data is then transmitted back to the tracking supplier’s server, via the mobile phone data network, where customers and users are then able to receive their vehicles location data via their internet based tracking applications.

In addition to transmitting the basic data, outlined above, many GPS Tracking devices are also able to further integrate with a vehicle and provide more detailed feedback.

Vehicle Tracking Unit
A vehicle tracking unit is a key part of any vehicle tracking solution. These devices are used to calculate a vehicle’s location and movements before then sending this data back to the user where it can be viewed on their vehicle tracking application.

The majority of vehicle tracking units that are used for modern tracking solutions use GPS technology to provide an accurate service. These types of units have a GPS antenna that is within the vehicle, which continually receives transmissions broadcasted from multiple GPS satellites that are orbiting the Earth.

The vehicle tracking unit uses the data received from multiple satellites, normally a minimum of 3 or 4, to accurately calculate its real time location, speed and direction of travel. All of this data is then sent back to the user, normally via the GPRS data network, where it is made available to the user via a web based tracking application.

The GPS network has been setup in such a way that there is always a sufficient number of satellites active to provide an accurate service anywhere in the world, providing that the tracking antenna is not obstructed, which can occur when in a tunnel or underground car park.

GPS adoption driven by Smartphones
“The smart phone is the key product driving the technology industry today—and social networking services and applications spurred by GPS-related features are critical elements in the smart phone market today,” said Dr. Jagdish Rebello, director and principal analyst for iSuppli. “This is illustrated by Google Inc.’s decision to make turn-by-turn navigation, LBS and mobile ads the central features in its bid to take on Apple in the smart phone market, and make up the central pillars of its strategy to increasingly monetize mobile search.”

iSuppli believes that PND makers are likely to answer the challenge brought by smartphones in offering differentiated, connected devices. iSuppli indeed noticed that “TomTom, in particular, has gone in a new direction with its latest connected PND—the GO 1000 Live.” iSuppli thinks that open up the platform to third party content and services provider is going in the right direction.

IWM co. is the main digital mapping company in Iran which develop Iran Digital map for Garmin GPS and Navitel systems.

The new versions of Iran GPS map for Garmin and Navitel are available here.

This type of partnership with content providers is likely to be more frequent because of the new Telmap strategy that wants to help wireless operators to position their mobile navigation solution as the best “local” solution against worldwide giants such as Nokia and Google and their “standardized” offer.

Telmap’s parent company, the London-based Science Navigation Group also owns Global Datapoint, a UK and Israel provider of event listings that is expected to roll out soon in new countries, is linked to this strategy. The mobile application WoZZon is one of the consumer front ends of this event database in the UK.
