What device measures distance by measuring time the time a signal takes to travel from a satellite to the device?

GPS receiver
1) The GPS receiver measures the distance from itself to a satellite by measuring the time a signal takes to travel that distance at the speed of light.

How do GPS systems transmit information over long distances?

GPS satellites circle the earth twice a day and transmit information to the earth. The time difference tells the GPS receiver the distance the user is from the satellite. By calculating the distances from several satellites, the receiver can determine and display the user’s location on the GPS unit.

How do GPS receivers use time to determine the distance from the satellites?

There are also clocks in the GPS receivers. Radio wave signals from the satellites travel at 186,000 miles per second. To find the distance from a satellite to a receiver, use the following equation: (186,000 mi/sec) x (signal travel time in seconds) = Distance of the satellite to the receiver in miles.

How does a GPS receiver determine the distance between you and the satellites?

A GPS receiver determines its own location by measuring the time it takes for a signal to arrive at its location from at least four satellites. Because radio waves travel at a constant speed, the receiver can use the time measurements to calculate its distance from each satellite.

What kind of information does a GPS satellite transmit to the GPS receiver?

The U.S. Space Force develops, maintains, and operates the space and control segments. GPS satellites broadcast signals from space, and each GPS receiver uses these signals to calculate its three-dimensional location (latitude, longitude, and altitude) and the current time.

What method can the GPS calculate the distance?

In theory, this is done by measuring the arrival time of the signal from the GPS satellite. This signal carries timing information from the atomic clock on-board the satellite and the measured time delay thus indicates the distance (multiplying the time delay by the speed of light gives the distance).
