Omnistar DGPS world map

Trimble announced on March 16 that it has entered into a definitive agreement to acquire certain assets related to the OmniSTAR GNSS signal corrections business from Fugro N.V.

The acquisition is expected to significantly expand Trimble’s worldwide ability to provide correction services for a broad range of land-based applications in addition to OmniSTAR’s current focus in agriculture. Fugro’s offshore marine business is unaffected.

Integer Aperture Estimation

For the complete story, including figures, graphs, and images, please download the PDF of the article, above.

Integer carrier-phase ambiguity resolution is the key to fast and high-precision GNSS positioning and navigation. It is the process of resolving the unknown cycle ambiguities of the carrier-phase data as integers. Once this has been done successfully, the very precise carrier-phase data will act as pseudorange data, thus making very precise positioning and navigation possible.
