Navigation and tracking of any vehicle have been a necessity throughout the years, but it’s only recently that a reliable system has been created to allow this necessity to be fulfilled and become a common reality.
On February 22, 1978, the first GPS satellite was launched by the name of Navstar 1, which initiated the large-scale system of satellites that ensure navigation and tracking. As of February 2016, 72 GPS satellites have been launched, while the minimum number for efficient operation is 24 GPS satellites that operate 95% of the time.
Although not all GPS satellites may be for public vehicular navigation, there are several online autoradio gps satellites that aid in that and this article will cover the working of a GPS satellite for auto reception.
Although GPS was launched initially for US military purposes – and it’s to note that the Global Positioning System comes under the US Department of Defense – it also allows the public to navigate through routes with ease and provides mapping options down to an absolute 5-meters.
Overview: Every GPS satellite for auto reception orbits at an altitude of around 20,000 km and completes two full orbits every day, and the numerous satellites make up the Global Navigation Satellite System Network. These satellites transmit microwave signals to GPS tracking systems, allowing the provision of information such as vehicle speed, location, direction, and time. This, in turn, allows any GPS satellite for auto reception to provide enough data to a GPS tracking system to allow real-time navigation as well as record navigation data on any journey.
Receivers: Although every GPS satellite for auto reception provides microwave signals, these are of particular frequencies and wavelengths so that GPS receivers can easily communicate with the satellites. If more than four GPS satellite signals are transmitting to one GPS tracker, the tracker can quickly generate a 3D computed view of the information.
Control: Such a vast network of satellites had to be watched over and monitored for maximum efficiency as well as the processing of intricate and sensitive information. There are several stations all across the globe that control the data that every GPS satellite generates.
Operation: Going into the details of the functioning of the system, we’ll state that GPS works on the principle of trilateration. For efficient operation, the area to be monitored has to be traced by at least three satellites above it and using the distance between the area and each of the three (or more) satellites, the accurate location of the vehicle can be easily generated. Such is the operation of a GPS satellite for auto reception.
Active/Passive Systems: There are two types of GPS tracking systems, namely active and passive. A passive GPS system works by monitoring the location and storing data based on specific events, recording a log of where the GPS receiver has traveled and storing it in a memory card. An active GPS system, instead, provides real-time information and navigation.
