A compatible device such as a smartphone or a dedicated navigation device has a built-in receiver chip that picks regular up signals from these satellites. Each signal is time-coded so the device can calculate how far away it is from the satellite based on the time the signal takes to arrive. By combining the distances from at least four satellites, the device can calculate its position to within a few feet.
It can also cross-reference this with map data to provide navigation such as driving directions. Not all phones have a GPS receiver, but those that do not may still offer navigation tools. One method is using cellular triangulation which works in a similar way to GPS but using signals from cellphone towers rather than satellites. Because the towers are nearer only three signals are needed to calculate a location, although the resulting location is not as precise.
Whether it is communication, entertainment, searching for information, or even traveling, technology surrounds us. Both are two entirely different technology in mobile phones or other devices. GPS is a navigation system that pinpoints the accurate location of the handset with the help of a satellite. GPRS is a technology utilized to transfer data using a cellphone network.
It is a portable navigation facility available on a smartphone. It is a technology utilized to transfer data on a smartphone. GPS is a satellite-based navigation system. The primary purpose of GPS is to provide Positioning service. GPS facilitates applications such as surveying, mapping, and precision agriculture. GPS communicates with satellites orbiting the Earth. GPS is accessible on land, air, or water.
GPRS is a cellular-based technology. The primary purpose of GPRS is to provide a voice and data facility. GPRS facilitates E-mail accessing, multimedia messaging, and video calling. GPRS communicates with the terrestrial tower. The range is limited and utilized on the land. Now that you have a good understanding of both the technologies, let us summarise the difference: GPS. A positioning service that can determine any position on the Earth Receives signals from Satellites Can be used on both land and sea, in any part of the globe.
A data service technology that provides wireless communication Receives signals from cellular towers Range is limited to land.
