Innovation: Checking the accuracy of an inertial-based pedestrian navigation system with a drone

I’m Walking Here!
An ingenious navigation technique makes use of how the human body works to develop an accurate pedestrian navigation system — one whose accuracy has been checked using drone imagery. read more

GPS World editor to moderate innovation panel at Munich Summit

March 6, 2017By

This year, the Munich Satellite Navigation Summit features an interactive session on the topic “Industry Meets Research: Innovation Drivers and Barriers in SMEs.” Fabio Dovis from Politecnico di Torino will chair the session, and GPS World magazine Publisher and Editor-in-Chief Alan Cameron will moderate the discussion. “Small and medium-sized enterprises (SMEs) and their innovative ideas are an important factor of... read more

Innovation: Guidance for road and track

January 14, 2016By

Real-time single-frequency precise point positioning for cars and trains
In this month’s Innovation column, we bring together, perhaps for the first time, single-frequency and real-time PPP. Our authors describe a series of experiments they have conducted on roadways and a railway achieving sub-meter horizontal positioning at a 95 percent confidence interval. Such accuracies may already be sufficient for freeway lane and railway track guidance. But we might expect even better accuracies in the future. After all, PPP is getting better all the time. read more

Proposed GNSS Navigation Messages for Improved Performance
In this month’s column, we look at proposed changes to the way navigation messages are formulated that could result in a future satellite navigation system providing faster fixes effectively giving receivers higher sensitivity and stronger performance. read more

Innovation: Getting There by Tuning In

September 4, 2015By

Using HD Radio Signals for Navigation By Ananta Vidyarthi, H. Howard Fan and Stewart DeVilbiss THE YEAR WAS 1906. On Christmas Eve of that year, Canadian inventor Reginald Fessenden carried out the first amplitude modulation (AM) radio broadcast of voice and music. He used a high-speed alternator capable of rotating at up to 20,000 revolutions per minute (rpm). Connected to... read more

Innovation: Carrier-Phase RF Ranging

June 8, 2015By

Precise, Accurate and Multipath-Resistant Distance and Speed Measurements
In this month’s column, we take a look at a short-distance two-way ranging system using a 5.8-GHz carrier to supply not only precise and accurate distance measurements but also complementary measurements of speed. read more

Innovation: Where Are We?

Positioning in Challenging Environments Using Ultra-Wideband Sensor Networks
The use of large transmission bandwidths offers a number of benefits, including accurate ranging and that application in particular is being actively developed for positioning and navigation in environments that are challenging to GNSS such as indoors and built-up areas. In this month’s column, we take a look at the work being carried out in this area by a team of researchers at The Ohio State University. read more
