Land Surveying
In the context of external land surveying, a base station is a GPS receiver at an accurately-known fixed location which is used to derive correction information for nearby portable GPS receivers. This correction data allows propagation and other effects to be corrected out of the position data obtained by the mobile stations, which gives greatly increased location precision and accuracy over the results obtained by uncorrected GPS receivers.

Famous quotes containing the words land and/or surveying:
“That land is like an Eagle, whose young gaze
Feeds on the noontide beam, whose golden plume
Floats moveless on the storm, and in the blaze
Of sunrise gleams when Earth is wrapped in gloom;
An epitaph of glory for the tomb
Of murdered Europe may thy fame be made,
Great People! as the sands shalt thou become;
Thy growth is swift as morn, when night must fade;
The multitudinous Earth shall sleep beneath thy shade.”
—Percy Bysshe Shelley (1792–1822)
“Upon looking back from the end of the last chapter and surveying the texture of what has been wrote, it is necessary, that upon this page and the five following, a good quantity of heterogeneous matter be inserted, to keep up that just balance betwixt wisdom and folly, without which a book would not hold together a single year.”
—Laurence Sterne (1713–1768)
