Is a highly accurate clock essential for GPS to function?
Yes. That's why there's one installed aboard every GPS satellite.
Why is your gps clock 3 minutes slow compared to correct time?
The GPS clock is three minutes slow because there isn't as much gravity around the satellite as there is on the surface, which makes time go by more quickly.
How does a GPS receiver calculate its distance from a satellite?
Very easily. The GPS receiver measures how long it takes a certain radio signal to travel from the GPS satellite(s) to itself, and from that, the receiver calculates the distance. It can do that because it knows precisely how fast the radio signal travels.If you have signals from at least 3 satellites, the process of trilateration (not triangulation) pinpoints the location where the 3 distances 'cross' each other. If you have 4 satellites 'locked in', then you will find out your altitude, too. (The process is not quite this simple, but to go on would be confusing.)The hard part is measuring the precise time it takes for a certain radio signal to travel from the GPS satellite to your GPS receiver. Well, hard if you do it, but very easy when the GPS receiver does it!First, each GPS satellite carries an on-board atomic clock. This clock is outrageously accurate, but even so, ground stations connected to the US Navy atomic clock system keep each satellite precisely at the correct time. Your GPS receiver has an on-board high-precision clock of its own.Second, when your GPS receiver first makes contact with the constellation of GPS satellites, it is sent an 'almanac' that lists where each satellite is, what it's precise time is, and other goodies. After reading the almanac, the GPS receiver sets itself to the precisely same time as the satellite constellation.Thirdly, when the GPS receiver gets a signal from the satellites, there is information in it that says precisely at what time the radio signal left each satellite, which is identical for all the satellites. Then your GPS receiver 'looks at its watch' and subtracts the 'sent' time from the 'received' time. The data in the almanac are updated by the satellite constellation every few hours so that your GPS receiver will always know where the satellites are and what their precise time is.Go back to the beginning and reread what your GPS receiver can do once it knows the precise travel time of the radio signal.
What does GPS stand for and how does it work?
GPS stands for global positioning system. The system consists of about 20 satellites, each containing an atomic clock. Each satellite continually broadcasts a signal announcing the position of the satellite and the time according to its clock. This is done to great accuracy and with high precision. A GPS receiver collects data from 3 or more satellites, and by measuring the differences in received times from different satellites can fix its position to an accuracy of a few feet.
What is the radius of asteroid vesta?

Do you need satellite radio to use gps?
No, that won't work.You need a special GPS receiver with a super-accurate clock in it (and lots of other goodies) in order to take advantage of GPS signals from the group of 24 GPS satellites.

Who is god roman name is vesta?

How do sea vessels determine their location?
They now use GPS just like in your car. If there GPS goes out, they have to navigate by a compass and dead rekconing, using the sun and stars with clock, maps and sextent.
