GNSS Pest Control
A new solution for GNSS multipath employs a multi-element antenna with RF signal switching and a single front end to reduce complexity, power consumption and cost. Correlator beamforming, initially used in the 2.4 GHz frequency band where it has proven effective at mitigating multipath in heavy industrial environments, has been successfully adapted for GNSS use. read more

Research: RTK with tight coupling of 6 low-cost sensors

January 10, 2017By and
Performance of RTK positioning, a fusion of GNSS and inertial sensors, in the city center of Munich.

A tight coupling of GNSS and inertial measurements is needed for both accurate and reliable positioning. The use of multi-GNSS is recommended to obtain a sufficient number of visible satellites in any outdoor environment. read more

tower-gnss-cranes-o

Modern tower cranes can reach a height of more than 200 meters. They operate in a complicated, chaotic and constantly changing environment. This creates obstacles for the crane operator: poor visibility and dead angles — places the operator can’t see. Aiming to solve the problem is the Augmented Crane Navigation System (ACNS) project, which provides innovative intelligent operation of tower... read more

Galileo deals 4 of a kind

December 2, 2016By
The Kourou launch team.

An Ariane 5 heavy-lift rocket launched four full operational capability (FOC) Galileo satellites on Nov. 17, accelerating deployment of the new satellite navigation system. The rocket carried Galileo satellites 15–18 from Europe’s Spaceport in Kourou, French Guiana, into space, releasing the first pair 3 hours, 25 minutes after liftoff, while the second separated 20 minutes later. All four are at... read more
