The rapid growth of vehicle tracking system business is quite inspiring and evident all over the world. Most vehicles in North America and Europe have started using the system and there is indeed an effective growth in Asian markets as well. According to a recent market study, it was found that there is an estimated growth of $30.45 billion by 2018, at a Compound Annual Growth Rate of 22.8%.
Key driving forces for adopting vehicle tracking system to the business
Apparent downsizing of tracking units and antenna enabling clandestine mounting and installation in smaller regions
Enhanced security due to the theft detection facility and real-time tracking of shipped goods

Moreover, there is the Russian GLONASS that is in a fully operating stage, the Chinese BeiDou Navigation Satellite System and Japanese Quasi-Zenith Satellite System are partially operationable, and Galileo (European Union's Global Navigation System) will be available by the year 2019. And the compatibility of these system however varies from single system to multiple system compliance, either one at a time or with parallel functionality.
One of the key issues is the location where the tracking application is used , when it is operating in the weak signal area, there will be interruption in parallel GNSS operation. Another consideration is the Government authorization, for example, in Russia, the ERA-GLONASS vehicle emergency call system requires GLONASS compatibility and hence, it should be scrutinized as …show more content…
Hence, it will be difficult to trace achievement and certainity in urban canyons especially, when it is in indoors or the receiver is within the metallic containers. This issues can be resolved using the following techniques:
1. Unified dead estimating
GNSS receivers can be improved with censor data, which helps to report distance and heading changes using the last known position. This kind of receivers when installed in automotive navigation systems, which facilitate smooth navigation within tunnels. In addition to this, accelerometer readings can also be augmented by careful consideration of vertical displacement. 2. Compound positioning procedure
In this procedure, you can add parallel system that speculate based on Wi-Fi cells or visible mobile cells whenever the visibility of GNSS satellite is blocked. You will be able to obtain information about a few kilometers distance and it is better than obtaining no positional information at all especially, in the case of useful shipments and vehicles.
