KVH Industries Inc. and manufacturer NovAtel Inc. today unveiled KVH's CNS-5000, a self-contained navigation system that combines fiber optic gyro (FOG)-based inertial measurement technology from KVH with GPS from NovAtel.
Hemisphere GPS today reported a 56 percent increase in revenues in the first quarter to a record $25.9 million, as compared to $16.7 million in the first quarter of 2007.
Oxford Technical Solutions (OxTS) has rolled out its Inertial+, an inertial navigation system that can be used with an existing GPS receiver to improve position measurements, according to the company.
A functioning Galileo system may still be some years away — current projections that plan on having a full satellite constellation in orbit within five years may prove wishful thinking. Nevertheless, Galileo can mean nothing but good things for survey and construction, and the sooner it gets here, the better.
Primarily developed for computing applications, such as pattern recognition, neural networks have been adapted for use in several fields of science, including geodesy. Those adaptations are needed because usually the situations and problems encountered in computer science are different from those in other fields. Geodesy is no exception.
Beneath the streets lie thousands of kilometers of cables and pipes. Buried decades ago, their exact location remains a mystery. At the University of Nottingham, researchers tested GPS and a system that pairs GPS with Global System for Mobile Communication (GSM) algorithms. Their goal: find a solution for mapping buried assets, which in turn will increase the efficiency of streetworks projects.
Although GPS is an efficient tool for deformation monitoring, it also is an expensive one for large projects. The authors developed a remote-controlled monitoring system using an electronic switching device for multiple antennas to monitor steep slopes at the Xiaowan hydropower station in China.
The Benchmark Survey System, developed for the U.S. Air Force's Holloman High Speed Test Track. replaces legacy NGA conventional survey techniques with a GPS-only system, maintaining sub-millimeter positioning accuracy while increasing throughput by 400 percent, with an 85 percent decrease in manpower. Results agree with recent NGA precise survey data to better than 0.6 mm horizontal and better than 1.0 mm vertical.
The American Society of Agricultural and Biological Engineers (ASABE) announced an effort to develop a standard on the dynamic accuracy of GPS equipment used in precision agriculture.
In a first of its kind study, a female snow leopard was fitted with a GPS collar that will provide researchers with an unprecedented amount of precise data on snow leopard movements and habitat use.
