There is no relationship between GPS (Global Positioning System) and magnetic fields. The GPS system is based on a network of satellites that provide a reference datum that is based on position, regardless of magnetic field.
To find the variation from true north, you can use a magnetic compass to determine the magnetic north and then calculate the angle between the magnetic north and the true north. This angle is known as the magnetic declination or variation. Many maps and GPS devices provide information about the current magnetic declination in a specific location.
No, GPS accessories are not typically interchangeable between GPS brands because each brand may have different specifications and connection methods. It's important to use accessories specifically designed for the model and brand of GPS device to ensure compatibility and functionality.
Earthmate GPS from Delorme can be used for mapping and navigation. The company has been around for 30 years and is very experienced in the field of GPS.
When they first get started, GPs earn between $40.76 and $62.23 per hour.
Compasses are devices that use a magnetized needle to find direction by aligning with the Earth's magnetic field. Some smartphones also have built-in magnetometers that can act as digital compasses by detecting magnetic fields. Additionally, certain navigation systems, such as GPS devices, may use magnetometers to assist in determining orientation and direction.
Navigation ! Even though we have GPS systems - a compass is ONLY reliant on the magnetic field of the earth. An electro-magnetic pulse could knock out ALL the GPS satellites - yet the earth's magnetic field will always be here !
In relation to what?
The purpose of a magnetic compass is to provide a reliable and simple method of determining direction by aligning itself with the Earth's magnetic field. It is a crucial tool for navigation, particularly in situations where other methods, such as GPS, may not be available or practical.
A compass is typically used to determine the direction you are heading by pointing towards magnetic north. It utilizes the Earth's magnetic field to provide orientation.
Nothing. A gps is the same as a gps.
No. Magnetic compasses work based on the Earth's mantic field, in space there is no magnetic field for the compasses to work with. A different system, possibly similar to Global Positioning System (GPS) might work, call it the Universal Positioning System. On certain rocky planets it could work, but some planets don't have a magnetic field, like Mars. So a traditional magnetic compass wouldn't work in space, or at least it won't get you where you want to go.
True North
The magnetic compass was replaced with more advanced navigation technology such as GPS (Global Positioning System). GPS provides more accurate and reliable information about a vessel's location, speed, and direction.
using a compass and not a GPS

One does not necessarily think of the Earth's magnetic field every day, but it does some important things. First, everyone knows, the Earth's magnetic field influences all magnets on Earth and the compass is the most famous. The Earth's magnetic field allows you to use a compass. Even without a compass some birds are able to detect the Earth's magnetic field and get a sense of direction. Second, the Earth's magnetic field protects us from the solar wind which is a high energy stream of charged particles coming out of the Sun. Occasionally, there is a great burst of these particles associated with a solar flare. Without the Earth's magnetic field these particles would hit Earth's atmosphere and create additional radiation. Though that radiation would not threaten life on Earth, it may be quite harmful. Satellites are a different matter and the assault of the charged particles has important consequences on GPS and communications and without the magnetic field The solar wind and the Earth's magnetic field together form the Aurora Borealis, the Northern Lights, so they would be gone without the Earth's magnetic field. The solar wind and the Earth's magnetic field are the main ingredients to what is now called solar weather. There is a complex interplay between the Earth, its atmosphere and the magnetic field which is currently the subject of much study. Oddly, the Earth's magnetic field helps hold on the the air. One way the Earth loses air is that the highest air particles are hit by the solar wind and knocked off the Earth. That is very much decreased because the Earth's magnetic field deflects most of the solar wind. There is some reason to believe that Mars lost its atmosphere after it lost its magnetic field and that is why Mars has only 1% as much atmosphere as Earth. Sometimes the Earth's magnetic field disappears or reverses or just gets all jumbled up when the currents that cause it in the Earth's core become erratic. This hasn't happened for about 10,000 years, but the geologic record shows that it has happened dozens of times and the length of calm periods like now can be a few thousand or a few million years long. A reversal of the Earth's magnetic field takes a few hundred years to settle down again, and so during that time your compass won't work, birds may be confused, Northern Lights become a vague glow and GPS and cell phones may be replaced by maps and wires. And, of course, it will be good to have stock in companies that sell sun screen.
If you are really wondering what is the difference between self and navigator GPS because you need to buy a new GPS that is not expensive, then you should buy the auto GPS navigator.
