PAJ-GPS Motorcycle Trackers have become increasingly popular among motorcyclists, especially large motorbike communities in North America, but what is the technology behind the trackers? To answer this we have to focus on what is behind GPS technology itself.
Today we know GPS thanks to the implementation that the main operating systems for smartphones have given it, specifically the applications that we use daily, such as Google Maps. Also due to the use given to it by express transport companies, it is also known thanks to its integration into cars and smartwatches for a couple of decades.
The Global Positioning System (GPS) accurately establishes the position of an object or person in latitude and longitude coordinates in any place on Earth where it is located, the variation can be between a few meters or even just centimeters, in some cases. Behind this technology, there is a complex system of 31 satellites with atomic clocks that basically never fail. In addition, there are several ground stations on Earth that function as receivers alongside these satellites.
To make it work, in essence, a user requires using four or more of these satellites and using trilateration, a mathematical method that determines the relative positions of objects using the geometry of triangles in a way analogous to triangulation, that is three-dimensional position. Of something.
Its development is attributed to Iván A. Getting, Bradford Parkinson, and Roger L. Eston, three engineers who worked at the United States Naval Research Laboratory, although the mathematics behind the success of its development was compiled by Gladys Mae West, an American mathematician, who in 1986 published “Data Processing System Specifications for the Geosat Satellite Radar Altimeter,” a 60-page illustrated guide that was the key to the development of GPS.
GPS was originally developed for the exclusive use of the United States Navy (and still belongs to them), but the international community reached an agreement for its open use in 1995, to be used by the general population under the pretext of improving maritime and air safety. For their part, there are some positioning systems prior to GPS:
1. OMEGA (1960)
2. TRANSIT (1964
3. TIMATION Satellite (1967)
4. NAVSTAR GPS (1973-1993)
5. GLONASS (Russian Federation)
PAJ-USA GPS trackers need a cellular network SIM to transmit the location to the software platform and you can even know the precise location of the vehicle through SMS text messages. A vehicle fleet management and control platform is required in which the data of all vehicles in the fleet will be displayed, that is, fleet management software.
For its correct functioning, there are three main sectors that must operate in coordination:
1. Space Sector: composed of 24-31 satellites arranged in six orbits.
2. Land Sector (DGPS): also called control sector. It is responsible for correcting the signal obtained from the satellites, as well as possible deviations from the orbit. They are made up of 9 stations: 1 general, 5 tracking, and 3 data.
3. User Sector: composed of antenna, amplifier, and receiver (whichever can be obtained). The team will be in charge of selecting the satellites that will provide the information it needs to calculate the position of the monitored object, measure the time between transmissions of the object, and obtain the time of its movements.
The combination of the three sectors provides time and position with global coverage, as offered by PAJ-GPS Motorcycle Trackers.
