Hi,
Most likely it's an antenna problem or something wrong with the `front end` section of the receiver. Then again, it also depends on your location. I wouldn't expect a GPS receiver to work well in a cave or close to large buildings, etc.
Hope this helps,

How can a GPS tell you where to go?
It uses a signal from a satellite that is revolving around the Earth right now.
What kind of signal is used in a GPS satellite?
radio waves
What does a gps satelite do?
A GPS satellite emits a very precise and accurate time signal that the receiver can use to calculate it's distance from the satellite.
Can a satellite radio get gps signal?
No. The satellites used to distribute Sirius/XM "satellite" radio operate on frequencies assigned to Sirius/XM "satellite" radio. They don't operate on frequencies allocated to the GPS system.
How many satellite signals do you need to get an accurate signal on a GPS?
at least 3. Alan x:)
How does a GPS system determine its position?
it sends signals to a satellite and tell where you are
How do gps systems works?
GPS, or more exactly GNSS, is a constellation of satellites that sends waves to the earth. To learn more, you can read this blog on GPS signal detection and accuracy. cyclope.dev
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.
How do you stop a satellite signal in a temple?
Microwave Radio Frequencies (RF) does not travel through dense metals. A metal roof would block the signal. If you try to get your position on a GPS inside the temple and cannot, then the satellite signals are blocked.
How does a cell phone GPS locator work?
A GPS on a cellular phone receives its signal from GPS satellites that are in the sky. When the GPS receives signals from more than one satellite, it can calculate the position and track exactly where the user of the cellular phone is headed.
How does gps tracking of a car work?
When a GPS system is placed in a vehicle it provides information on the exact location by radio-navigation system by 24 satellites and their ground stations. A microwave signal is transmitted from satellite to the GPS device.
How does a gps navigation system tell you where to go?
A satellite that orbits earth tells it which way to go.
