reference station

[′ref·rəns ‚stā·shən]
(oceanography)
A place for which independent daily predictions are given in the tide or current tables, from which corresponding predictions are obtained for other stations by means of differences or factors.
A place for which tidal or tidal current constants have been determined and which is used as a standard for the comparison of simultaneous observations at a second station. Also known as standard station.

The mobile station corrects the positioning result by receiving the difference value from the reference station, which can improve the positioning accuracy.
To realise this objective, and calculate the dynamic movements of the Abu Dhabi reference station network, satellite data and readings of these stations must be processed in conjunction with a reference satellite accurate data and readings of several Global Reference Stations of IGS, specially designed for this type of calculation and references.
Therefore, for each test series, five reference stations are chosen based on distance, altitude criterion, and amount of common data.
Several NRTK techniques exist and the most commonly used at present are, for instance, the Master Auxiliary Concept (MAC) [4, 5], the Virtual Reference Station (VRS) concept [6], and the FKP techniques [7], as well as the Network Adjustment (NetAdjust) concept developed by Raquet and Lachapelle [8, 9].
The reference stations of Korea are densely located ranging from 30 to 50 km for most of the baselines, which should be a worthy infrastructure for NRTK positioning.
The translation parameter values increase proportionally to the number of used fixed reference station. The scale and orientation of the network remains consistent with the changing number of fixed reference stations.
TAG's military GNSS survey system will deliver enhanced on-site GPS positioning with centimeter-level accuracy using Real-Time Kinematic (RTK) software combined with wireless data from the reference station and rover units.
It consists of inspecting the entire prop and measuring blade width, thickness and angle at each reference station (defined distances from the hub), check face and edge alignment, grind out nicks and gouges, strip the paint, inspect for cracks, inspect the bolt holes and hub, correct any errors in blade angle and track and then paint and balance the prop.
A central reference station (station 77) in addition measures air pressure and net radiation and employs multiple rain gauges.
It's a one-stop solution, said Wendy Watson, Director, Reference Station OperationsGNSS reference networks.
