Veripos has extended the Baltic sector of its European multi-source Differential GPS service network with the establishment of new reference station facilities in Stockholm. Meanwhile, a new station has also been added to the Americas regional network serving offshore users in North, South and Central America as well as the Caribbean with installation of similar facilities in San Diego for enhanced coverage of eastern sectors of the Pacific.
Commenting on the latest extensions, Veripos Technical Director Bobby Johnson said that they marked a further stage in the development of the Company's worldwide precision positioning capability as a result of increasing demand for its services from leading offshore users.
Members of the US Geological Survey were filmed while out on the Missouri River at Williston, North Dakota, USA, performing a hydrographic survey to monitor the state of riverbed erosion. They were using a multibeam echo sounder which transmits sound energy and analyses the return signal (echo) that has bounced off the riverbed or other objects. Multibeam sonars emit sound waves from directly beneath a ship's hull to produce fan-shaped coverage of the riverbed.
