The ease and simplicity of satellite navigation or Sat Nav devices have made them a welcome car accessories these days. The devices have made the stressful car journey to an unknown location a joyous occasion. These devices are equipped with features like turn-by-turn voice directions, highlighted points of interest (like ATMs, hotels, hospitals) which have made them a much sought after personal travel assistant.
The Sat Nav systems provide you autonomous geo-spatial positioning with global coverage. The satellite navigation receivers combine signals from multiple satellites and reduce errors by using techniques such as Kalman filtering to combine the constantly changing data into a single estimate for position, velocity and time. The Sat Nav systems, also known as Global Navigation Satellite Systems (GNSS) allow small electronic receivers to determine their location within a few meters using time signals transmitted by satellites. Based on their generations, the GNSS has been classified as GNSS -1 and GNSS -2.
Transit was the first satellite navigation system developed by the US military in 1960s. Satellite navigation is regarded as a force multiplier now-a-days. The system's ability to reduce unintended casualties is of particular advantage in wars where public relations are an important aspect of warfare. The satellite navigation was originally intended for military use but has found applications in civilian use of late. Currently, the United States' NAVSTAR Global Positioning System (GPS) is the only fully operational GNSS.
The Sat Nav systems have been put to a wide variety of use like navigation through hand-held devices fitted in cars, search and rescue operations, surveying and geophysical sciences. Several popular brands like Garmin, TomTom, Road Angel and Navman have launched their newest sat Nav devices with easy to use menus, safety camera locations and large touch screens. The systems have been developed so that they can be operated straight out the box and straight into the car.
