what is gps unit?

Answer 1

It tells/shows you where you are and how to get to a certain Location. Used by Boaters, Planes/Airliners. And Now Cars.

Answer 2

Global Positioning System (GPS), is the only fully-functional satellite navigation system. More than two dozen GPS satellites orbit the Earth, transmiting radio signals which allow GPS receivers to determine their location, speed and direction.

Since the first experimental satellite was launched in 1978, GPS has become indispensable for navigation around the world, and an important tool for map-making and land surveying. GPS also provides a precise time reference used in many applications including scientific study of earthquakes, and synchronization of telecommunications networks.

The United States Department of Defense developed the system, officially named NAVSTAR GPS (Navigation Signal Timing and Ranging Global Positioning System). The satellite constellation is managed by the United States Air Force 50th Space Wing. Although the cost of maintaining the system is approximately US$400 million per year, including the replacement of aging satellites, GPS is free for civilian use as a public good.

In late 2005, the first in a series of next-generation GPS satellites was added to the constellation, offering several new capabilities, including a second civilian GPS signal called L2C for enhanced accuracy and reliability. In the coming years, additional next-generation satellites will increase coverage of L2C and add a third and fourth civilian signal to the system, as well as advanced military capabilities.

Answer 3

A gps, or global postitioning system, is a series of connected satellites in geosynchronus orbit (stays above the same spot of earth always). Using the satellites and your own handheld device leads to a mathematical equation which allows you to find your position on earth plus or minus a couple of feet.

I believe(not sure) that the signal can be disrupted, so make sure you have a map too.

Answer 4

A GPS unit is a device that interfaces with sattelites in space. It can then tell from the info it receives exactly where you are on the earth, sometimes with accuracy as close as 2 ft

Answer 5

interior the U. S., the position the signal from a GPS satellite tv for pc is amazingly extreme - we are talking ninety 5%-one hundred% each and each and every of the time on the city parts, and seventy 5%-ninety% in rural parts - GPS gadgets do not make that many blunders. affirming that, although, my Garmin once took me to an FBI place of work in New Jersey when I requested for the Crowne Plaza motel in NYC. average although, they're quite good and precise. even with the actual shown truth that, in case you wait a even as, the european are launching Galileo which will be precise to 2m everywhere on the globe - GPS is precise to fifteen-20m.

Answer 6

Gps stands for Global Positioning Satellite. It will give you a longtitude and a latitude reading and is used to accurately pinpoint your location anywhere on the globe.
Google it for more info.

Answer 7

Global Positioning unit.It utilizes timing differential between at least three of the 14 geostationary satellites to calculate altitude & near exact position on the globe.

Answer 8

Global Positioning System.

It's like a map built into a radio that is linked to a satellite. It tells you where you are and how to get where you are going.

Answer 9

It is unit that help you know where you be on d planet.
