Xsens Adds Active Heading Stabilization to IMU

April 2, 2015By

In the latest update of its Motion Tracker product portfolio, Xsens has added active heading stabilization (AHS) to its core sensor fusion algorithms on the MTi 10-series and MTi 100-series. Both series are MEMS-based inertial measurement units (IMU), attitude and heading reference systems (AHRS), and vertical reference units (VRUs). The AHS algorithm delivers fundamentally improved heading tracking accuracy, Xsens said. The improved robustness in... read more

Expert Advice: The Impact of RFI on GNSS Receivers

April 1, 2015By
Dovis-Fig1-excerpt

By Fabio Dovis When subjected to very strong interference, a GNSS receiver can be totally blinded and stop working. This is often the scope of intentional jammers. However, in a number of cases the presence of interference is severe enough to significantly decrease receiver performance, but not so much as to make the receiver lose its lock on the satellite signals... read more

Spectracom Adds India’s IRNSS, Japan’s QZSS to Simulator Capabilities

All GNSS Attend, But Galileo Gets the Spotlight

March 30, 2015By

First and foremost, let’s give a big hand to Adam and Anastasia, the two Galileo FOC satellites that were successfully launched on March 27. Following the not-so-successful Galileo launch in August, it was imperative that this go smoothly. Although the Double-A launch occurred after the conclusion of this year’s Munich Satellite Navigation Summit, anticipation of the event set the context... read more

GNSS Constellations March On

March 25, 2015By

This week nearly all the global navigation satellite systems will push their spatial presence one or two steps further, or higher, if they perform as scheduled. Rarely if ever has there been such a concentrated period of activity in the catapult category. Are we witnessing the real dawn of the multi-GNSS era? GPS, Galileo, BeiDou, and IRNSS all have positioned... read more
