GPS Technology and Application
We are happy to show our company
Global Positioning System, GPS
GPS is one of the oldest wireless technologies that works by transmitting information from GPS satellites to a GPS receiver via radio signals and is the basis of many modern wireless technologies. It has a free, open, and reliable character and is used in creative solutions for data transmission.
The most popular and commonly used satellite navigation system in the United States is NAVSTAR or GPS. The first time that the U.S. Department of Defence put the satellites to use only for military purposes. Soon after, they were made available for civilian use in the 1980s.
GPS is a collection of 24 satellites in the space around the Earth, the receivers, and the control segment on the ground.
In the GPS system for computation of the location and time of the objects, special mathematical methods and physical rules are used. To calculate the distance from the GPS receiver to each satellite, the satellite signal propagation time is multiplied by the signal transmission rate. (distance= speed* time)
The GPS devices, by knowing the distances of at least three satellites and using the trilateration method, determine the position of the objects on Earth, and also, in this process consider Einstein’s general theory of relativity for error compensation.
2D or 3D Trilateration is a way that may decide the location with the aid of understanding the gap between two or three Geographical coordinates.
in addition to three dimensions; longitude, latitude, and altitude; the GPS signal provides a critical fourth dimension – time. GPS satellites have atomic clocks that keep the most precise time, this time signal is accurate to less than 10 billionths of a second.
Time technology is one of the new applications of GPS technology, due to the accuracy and reliability of GPS time, and has been freely available worldwide.
Precise time is crucial to a variety of economic activities around the world.
Power grids, banking systems, and mobile networks all rely on precision timing.
Free use of GPS time allows you to rely on the exact time to save costs and greatly improve efficiency. For example, wireless telephone and data networks use GPS time to keep all of their base stations in perfect contemporize.
GPS as an essential infrastructure element in transmitting information has extensive applications. GPS service increases productivity in a large segment of the economy. In the farming, construction, mining, surveying, package delivery, and logistical supply chain management industries GPS is a powerful and dependable tool. GPS works at all times and in almost all-weather conditions.
Examples of GPS applications:
- Location: Determining a position like a car locator,
- Navigation: Getting from one location to another.
- GPS Tracking: Monitoring objects, tracking your pet, tracking vehicles, School Bus Tracking, Trailer Tracking, or personal movement.
- Mapping: Creating maps of the world.
- Timing: Making it possible to make precise time measurements.
We at Arshon, used GPS on a lot of time-critical projects, such as wireless network timing and remote time-stamped data recording, and more.
Arshon Technology GPS Projects
When combined with other sensors, computers, and communications systems, GPS improves safety, security, and operational effectiveness in tracking systems. The technology helps reduce delays, and operating costs while increasing track capacity, customer satisfaction, and cost-effectiveness.
Arshon Technology designed and manufactured multiple GPS-based systems in various devices and applications. Our Electronic Design team as well as our Firmware Design team are very much familiar with this technology and the necessities around it.
Arshon provides customized GPS solutions for GPS Tracking applications such as:
In such cases, combining GPS satellite signal information with 3G or LTE cellular or LoRa technology provides a bespoke tracking system solution with its own advantages. We use GPS and IoT technology together and they complement each other. The IoT collects, monitors and controls real-time data about the behavior of smart devices, and GPS provides the physical coordinates of the device. These systems complement each other.
They form the basis of smarter cities, innovative products of different types of tracking systems such as self-driving cars and health-related wearable technologies, and a vast connected ecosystem. The transmitted information is stored in the clouds or on remote servers (iotLINKS) and provides personalized analysis to the user by studying the stored data.
