As the GNSS world starts to appreciate the era of multiple global constellations, it’s probably worth considering the impact on aircraft navigation, GNSS airborne receivers and what these changes might soon bring to those who develop and use GNSS for airborne en-route navigation and approaches....More>>

When Europe decided to pursue first EGNOS and then Galileo, two overriding incentives pushed the decision makers over the edge and into multi-year funding of very significant GNSS projects. The primary motivation was to ensure that satellite navigation capability was under European "sovereign"...More>>

When I first heard of IFEN, it was a competitor on the EGNOS and Galileo programs that NovAtel was trying to get into. Each ITT (Intention To Tender) that our team in Calgary bid on, we were to be weighed against what IFEN or Septentrio had proposed. NovAtel did eventually capture its first study...More>>

During the Institute of Navigation Satellite Division conference (ION GNSS 2011), I may have made a major mistake by being dragged kicking and screaming into the controversy that dominated its opening days. Excitement can be a relative term — if the sheer panic, and doom and gloom of what appears...More>>

China represents a huge potential market for Western GNSS companies, even though the country has a strong and growing GNSS capability of its own. Before booking a flight to Shanghai or Beijing, however, some careful preliminary research will likely pay off: looking for potential Chinese industry...More>>

The exhibit hall is nearly full for the ION GNSS conference in September, and this year's crop of new products and technology promises to showcase the very latest and greatest. In recent years some companies may have cooled a bit on exhibiting, but this fall has all the earmarks of a resurgence. As...More>>

In a world where there is more and intentional and unintentional interference with GNSS, it’s a little comforting to hear that technology has been developed which can help us fight back. The proliferation of affordable "Personal Protection Devices (PPDs)" used to mask GPS location — for users...More>>

There is so much going on around the world in GNSS applications and developments that when we try to report what’s going on in a particular location, all we can really do is provide a snapshot. Each snapshot is simply a momentary picture captured at a single location — there really could be an...More>>

Landing airplanes with GPS is not a new concept. People were demonstrating the feasibility back in the early 1990s. But landing transport airplanes in commercial airline service is something that’s only just getting to be a regular occurrence. Before we go on, maybe we need a short side trip into...More>>

When I first visited Beijing a few years ago, I came there from a stop in India. This was just before the Olympics in 2008, but there were signs then of big-scale preparations in terms of highway infrastructure and building. As the two most populous countries in the world, India (1.13 billion...More>>
