Geopositioning
Geopositioning is the process of determining or estimating the
Geopositioning yields a set of
Specific instances include:
Background
Geopositioning uses various visual and
The calculation requires measurements or observations of distances or angles to reference points whose positions are known. In 2D surveys, observations of three reference points are enough to compute a position in a
A practical example of obtaining a position fix would be for a ship to take
The process of combining multiple observations to compute a position fix is equivalent to solving a system of
The result of position fixing is called a position fix (PF), or simply a fix, a position derived from measuring in relation to external reference points.
