Paper presented at the Offshore Technology Conference, May 4–7, 1981
Paper Number: OTC-4157-MS
... on a moving vessel, in which each position fix is used independently to update the dead-reckoned position, fixed point survey requires data from multiple satellite passes at a single location. With appropriate processing techniques such data can be used to obtain excellent survey results, thus avoiding...

... improvements is to improve the average NNSS system accuracy for moving users by a substantial amount. For example, as will be shown later in the paper, for a vessel moving with fairly uniform speed during a satellite pass, the typical positioning accuracy without having to know the velocity is about 100 meters...

... of the Transit System. First is a unique fixed site survey technique, applicable to positioning of land stations or of offshore drill rigs. The technique employs the raw data gathered from several satellite passes to obtain a single, three-dimensional (latitude, longitude, height) position fix to an accuracy...
