Satellite Navigation is just as accurate as GPS, having a 1-10 meter buffer zone. Both use a similar system, having satellites in orbit to triangulate a position. Satellite Navigation, better known as GLONASS, is used mostly by the Soviet Union while GPS, is use worldwide and the widest used system.
GPS signals are processed in the GPS unit and displayed, and they are also processed via three Global Position Satellites. All four units work together and process GPS signals (some to the satellites from the GPS, and some from the satellites to the GPS) to create an accurate position.
I'm assuming you are talking about GPS when you say "satellite." RF tracking can be directional. It takes three RF receiver stations to triangulate the position of an RF transmitter and is usually less accurate than GPS. RF is also more limited by range, so the RF tracking stations are usually required to be mobile depending on the strength of the transmission signal.

The Global Positioning System (GPS) is a space-based satellite navigation system that consists of a series of satellites used for locating places anywhere on or near the Earth. GPS became fully operational in 1995.There are also a number of satellites that take high-resolution imagery of earth including GeoEye-1, QuickBird, WorldView-1, WorldView-2, and others. High-resolution images combined with a precise location can help to locate any place on the planet.

Global Positioning System (GPS) uses the signals from geosynchronous satellites to provide accurate position information for navigation. As such utilizing GPS for navigation amounts to utilizing satellite navigation ("sat nav"). Note that while GPS, which was developed by the US government is the most widely used satellite navigation system, Russia also has the Global Navigation Satellite System (GLONASS) deployed which can provide essentially the same satellite navigation capabilities - and can be used in along with GPS to get faster and more accurate position information. The EU, Japan, China, and India are also working to deploy a satellite navigation systems.
The Global Positioning System, or GPS, is a network of Satellites used for accurate navigation of ships and aircraft.
Satellite navigation is what it stands for. But it is called a 'GPS'
According to my research the auto GPS navigation is very accurate. This is an article you may find interesting http://automobilegpsnavigation.co.cc/?tag=accuracy
Both Russia and the EU have similar satellite based systems in operation, all you need is a receiver that can decode them. There are already a few navigation receiver models that are multisystem compatible, but they are much more expensive than simple GPS only navigation receivers. Nonsatellite based navigation systems (e.g. LORAN) are much harder to use and much less accurate than GPS and the other satellite based systems similar to it.
The Satelite Navigation System uses Global Positioning System to find where you are
A GPS satellite emits a very precise and accurate time signal that the receiver can use to calculate it's distance from the satellite.
It's super-easy to use GPS navigation. Just plug in your destination into the GPS device. A satellite automatically detects your current location and gives you step-by-step instructions on how to get where you need to be.
Marine navigation systems are just as accurate as any other navigation system. There will possibly be some inconsistencies here and there, but that is always to be expected with GPS systems.
A satellite that orbits earth tells it which way to go.
It depends where and how often the device downloads the GPS information. Streets and roads are always changing, so the GPS device must download updates to be accurate.
Global Positioning System (GPS) is a system of satellite tracking that uses a network of satellites to determine the latitude and longitude of a person or object on Earth. It provides accurate and real-time information about the location, speed, and altitude of the target. GPS is widely used in various applications, including navigation, transportation, and outdoor activities.
