Virtual Reference Station.* Trimble says its Virtual Reference Station (VRS (Video Relay Service) A communications service for the hearing or speech impaired. A VRS is the video counterpart of a TTY relay service, in which the user types on a terminal, and the relay operator speaks the messages to the recipient (see TDD/TTY). ) is a new solution for GPS infrastructure which lets users achieve long-range, real-time kinematic kin·e·mat·ics n. (used with a sing. verb) The branch of mechanics that studies the motion of a body or a system of bodies without consideration given to its mass or the forces acting on it.

The VRS enables centimeter-level positioning without setting up a local reference station and overcomes previous limitations with high precision GPS. Because the system reduces systematic errors in the reference station data, the distance at which the rover receiver is located from the physical reference stations can be increased up to 50 kilometers, from 10 kilometers previously, with centimeter-level accuracy. |
