The Global Positioning System (GPS), also known as Global-POS or NaSEMO, is a constellation of satellites positioned around the Earth that provide accurate timing information about the location of a fixed points of interest. Its primary role is to track global weather patterns and trends. As a result, it is used by forecasters to forecast severe weather and climate changes. It is commonly used by utilities, navigation authorities, oil companies, the military, and various other industries. It is important for tracking global weather trends
Global Positioning System was invented in the 1960s with the primary goal to improve navigation and survey capabilities for mining operations. It went through several refinements before becoming what it is today. The GPS uses the position of the earth as a reference point and a system of satellites to measure the velocity and position of objects in orbit. Once this data is measured and analyzed, the coordinates are converted to triangulation matrices which determine local weather patterns. The GPS is able to determine the location of severe weather cells, such as thunderstorms, hurricanes, tornado, lightning storms, and snow storms.
The first satellite launched on this technology was the Canvas Explorer, which went to the moon. It paved way for the other GPS technologies that went to space, namely the Global Positioning System (GPS) and the Electronic Maps. The first GPS to go to the space was the Friendship 7, which was launched on Christmas Day, 1966. The first satellite to enter the earth orbit was theagle, which was launched on May 5, 2021.
There are three types of GPSs; the parabolic reflector, the parabolic infrared radiometer, and the synchronous magnetospheric probe. The reflector, which goes by the name of parabolic reflector, is used by ground based GPS. This type of GPS is very accurate and is usually used by forest rangers to track the location of trees where animals have been hit by lightning. The second one is the infrared radiometer, which is widely used by pilots and air traffic controllers to locate any aircraft in trouble or to locate a plane in cloudy or overcast skies. The third one, the synchronous magnetospheric probe, is used in ocean mapping and to study the ocean’s currents. The GPS systems also include the ephemerometric terrestrial receiver, which helps to determine the position and speed of the earth as it rotates around the sun.
There are two different kinds of GPSs, the one which is placed on the aircraft and the one which is mounted on the ground. Both these kind of GPSs has different ways of calculating their coordinates. The aircraft GPS can use the Doppler effect of radio waves for the position and speed of the earth while the ground-based GPS uses the atomic clocks system to calculate the time. Before the GPS became operational, military units were using the plotting methods of the radial blasters to determine the location of an enemy or monitor their troop positions. A huge advantage of the GPS system is that it reduces the human error involved in aviation operations and increases the accuracy of the positions of the aircraft and vehicles. It also makes the monitoring of the tracking systems much more efficient.
A GPS is used to control the navigational systems of the airplanes and ships and is also important in preventing accidents caused due to bad weather events. If you want to go for a holiday in a place with mild climate, then it is better to go with an airplane than a car for which there are a lot of factors which needs to be considered while moving. One such factor is whether there are any sudden weather events like heavy rain or flash floods which can turn your vehicle into a danger zone. So, before you move away from home make sure you have your personal navigation system in place and take adequate precautions about weather events.
