Nav-e-gate4less Rolls Out Latest Navigation Products


Sustaining the rich legacy in providing navigation products and accessories, Nav-e-gate4less has rolled out three satellite navigation products, Garmin Nuvi 3xx Map Update, Garmin Nuvi 3xx Firmware Update, Garmin eTrex Firmware Update.

Kemnay, Scotland, United Kingdom, November 26, 2015 --(PR.com)-- Nav-e-gate4less is one of the leading suppliers of a vast assortment of navigation products and accessories at cost-effective prices. With a growing stature in the market segment, the company continue to build on trust and loyalty gained from legions of customers from across the world.

A satellite navigation system (satnav system) comprises of satellites, employed by a company or a country for that matter, for the purpose of geospatial positioning. Geo-spatial positioning is a technical term to be regarded with a specific location on or above the earth relative to a 3-dimensional space. A satnav system is programmed to locate longitude, latitude, altitude, and locale-centric information, among others. Further, it is worth noting that unlike commercial systems, which yield accurate information to within a few meters, high-end systems leverage the greater capabilities and thereby can output accurate information within centimetres. A signal broadcasted by the satellites contains orbital data, in addition to the exact time for transmission of the signal. The orbital data is integrated into a data message. This data message is superimposed on a code, intended for a timing reference.

Technical Nuts-and-Bolts of Sat Nav Systems

The satellite employs atomic clock, which serves as the most accurate frequency and time standards. The main purpose of an atomic clock is to maintain synchronization among satellites in the constellation. This is achieved by measuring the time of broadcast encoded in the transmission which is subsequently compared with the time of reception, as provided by an internal clock. In this way, accurate estimation of the time-of-flight to the satellite is accomplished. Moreover, triangulation is used to determine location, especially considering the fact that the receiver may measure signals directed from several satellites at the same instance of time. Triangulation refers to the process of determining the location of a point, relative to two known points and a given angle.

Factors for Calculating Location Data

The transmission includes meticulous locations of satellites and the time-of-flight of the signal comes handy for calculation of the distance to each satellite. Further, the receiver carries out some mathematical calculations for the determination of the location on earth. The more the number of satellites a receiver can track, the more accurate will be the calculation of location data. Generally, it is the case that the receiver factors in four parameters i.e. longitude, latitude, time, and altitude. As a result, the receiver tracks down at least 4 satellites for the calculation of four unknowns. Moreover, in case fewer satellites are used, the potential for errors in estimation increases.

Although the basic triangulation is not an intricate process, the known points i.e. satellites travel at a very rapid pace and the curved surface of the earth adds an element of complexity to the whole scheme. Owing to it, local augmentation systems are used. Further, use of the regional data sets facilitates local geographical description and thereby yields more accurate information.
