refers to a GPS receiver which either moves along a trajectory to be positioned (e.g. for kinematic positioning) or from point to point to be positioned (e.g. semi-kinematic or rapid static), and whose measurements are combined with those from a monitor receiver for relative positioning (also referred to as a remote)
In the late 19th and early 20th centuries, ice hockey consisted of seven positions. Along with the goaltender, two defencemen and three forwards who remain today, a Rover was also part of the team. Unlike all the others, the rover did not have a set position, and roamed the ice at will, going where needed.
