Riegl Laser Measurement Systems and Applanix Corporation announced today that the Applanix AP50 GNSS-inertial sensor system was successfully integrated with Riegl’s VQ-820-GU topo-bathymetric airborne laser scanner on board the Schiebel Camcopter S-100 UAV. The Riegl VQ-820-GU is specifically designed to survey sea beds and the grounds of rivers or lakes, and is well suited for combined land and hydrographic airborne... read more

Urban GPS Navigation Improved 50-90 Percent, Researchers Say

February 13, 2013By
gpsbooster-1

A new system developed by Universidad Carlos III de Madrid (UC3M) researchers uses sensors to improve the ability of GPS to determine a vehicle’s position compared to use of conventional GPS devices by up to 90 percent. The prototype can guarantee the position of the vehicle to within 1 or 2 meters in urban settings, the researchers said. The system... read more

Sensor Fusion in Forestry

July 1, 2010By
Robotic wood harvester.

Modern machines such as wood harvesters can automatically cut trees and remove branches, but an expert is still needed to plan a thinning and to mark the trees to be felled. The process can be accelerated if the forest ranger can virtually mark trees to be cut, using geographic coordinates instead of colored crosses sprayed on the stems. This requires the robotic wood harvester to be able to locate itself accurately to enable automatic navigation to the next tree for cutting. Absorption of the GPS signal in the forest canopy leads to poor results, however, with errors up to 50 meters and more. read more

Pulling in All Signals

March 1, 2010By
Melgard-Open

Adding GLONASS to GPS gives a total of about 50 satellites, for a significant improvement in navigation availability, reliability, robustness, and convergence time through a new multi-GNSS precise point positioning (PPP) service. System performance and field results demonstrate that there is no need to await future constellations — better performance is available now. read more
