Abstract
We have successfully developed application technologies of GPS in the Oceans. The progress of technologies in our company based on continuous investigations with some manufactures.
Firstly, we have introduced high-precision D-GPS to survey system of ocean depth. Secondly, we have constructed RTK- OTF-GPS to manage data automatically. This system is applied to constructions in the oceans.
Hitherto, GPS surveying required an initialization of "rover" receivers before use. If satellites signals are blocked, then the surveyor must go to a known point to re-initialize the system. However, our new GPS can re-initialize while you're moving-"on the fly" (OTF).
Key Features:
·GPS provide gains on projects when line-of-sight is a problem, such as sties rolling terrain, large equipment, rain and fog problems, and so forth.
·Centimeter-accuracy in real-time,
·Multiple rovers form one base instrument station,
·Automatic initialization while stationary or while moving,
·GPS observations and positions are available directly from the field.
