Setting Sail with GNSS-Guided Robotics
Ontario’s Clearpath Robotics and sister company Echostream Environmental Data Systems are creating advanced autonomous vehicles with sensors and dual-frequency GNSS and inertial technologies for academic research and real-world bathymetry.
Inspired by her engineer father, this Scotland native has pursued an independent course to build a wide-ranging career in satellite navigation.
A GNSS Network for Investigating Ionospheric Behavior in Sub-Saharan Regions
Scintillation caused by solar-induced ionospheric activity continues to be a potential problem for GNSS signals used for navigation purposes. Understanding the potential for scintillation and its effects on GNSS networks is critical as researchers attempt to address this still-unquantified threat.
Silver Linings for GNSS?
The Galileo satellite launch failure is not really an unmitigated disaster, and in the long run several good things will probably come out of this.
A team of researchers describes the development of a custom system for monitoring and collecting data on ionospheric scintillation and reports on its performance at facilities in the equatorial and arctic regions.
As a result of its spotty funding history, the civil community was, as of last year, some $50 million to $100 million short on its original commitment to the GPS program.

Sizing Up the Earth
Let’s get literal for a moment. What shape is the world in? GNSS can help us answer that question.
