Global Navigation Satellite Systems Positioning Concepts

At their core, Global Navigation Satellite Systems (GNSS) are a timing system where all satellite clocks are precisely synchronized. GNSS satellites broadcast coded signals at exact times, and the user's receiver collects the coded messages.

What are the two techniques for GPS positioning?

Positioning with GPS can be performed by either of two ways: point positioning or relative positioning.

How accurate is GNSS positioning?

However, not only is this impracticable for consumer GNSS devices, the GPS satellites themselves, in particular, are only accurate to about 10 nano seconds (in which time a signal would travel 3m).

How do GNSS receivers determine your location?

There are satellites out there in space, and each of them has its own orbit. Every satellite transmits the signal which includes its exact position at a particular moment of time. The receiver accepts this data and uses it to determine its position.
