The Chalmers system uses satnav signals to measure sea level

Measuring sea level is not only an invaluable tool for pilotage, navigation, aeronautics, cartography, sea charting, and geology, it’s also a fundamentally important metric for measuring possible evidence of climate change, and for measuring the direction, extent and rate of such change. Johan Löfgren and Rüdiger Haas of Chalmers University in Sweden have developed a new way of measuring sea level that uses satnav signals for constant, real-time monitoring that promises new insights into many fields, including climate change.  Read More

China’s independent Beidou satellite navigation system has been operating since 2000. Consisting of just three satellites (and one backup), that first generation system offered only limited coverage to customers in China and neighboring regions. Now, to end any reliance on the US-maintained Global Positioning System (GPS), the second generation of the Beidou system has begun operations. The system currently consists of 10 satellites and covers the Asia–Pacific region, with the number of satellites gradually increasing to a total of 35 that will cover the entire globe by 2020.  Read More

Simulated display for the True3D satnav system (Image: Making Virtual Solid)

Developed by the California-based company Making Virtual Solid, True3D is billed as "an augmented reality navigational display engine designed to provide non-distracting, translucent location guidance." That's another way of saying that True3D takes the head-up display (HUD) to its logical conclusion - it uses a 3D projector to beam the display across the entire front window of the car, therefore keeping the driver's eyes on the road by unobtrusively blending in with the real world beyond the windscreen.  Read More

The UK's Highway Code advises the use of care when approaching a level crossing and to only drive onto a crossing if the exit is clear on the other side. After all, finding yourself blocked on the track when a train is coming is probably not a great position to be in (unless you can depend on Hancock to stop the train before it hits). While such things may seem like common sense, that doesn't appear to prevent drivers from taking stupid risks. Now Network Rail and Garmin have teamed up to create a special sat nav app which will sound a train-like whistle when a driver approaches a level crossing.  Read More

If you drive a truck for living, a sat/nav can be a handy business tool. With most of these units designed for car users, the market for dedicated trucking units has expanded in recent times. The latest offering from Cobra Electronics – the 7750 Platinum – includes a 7-inch screen, 3D maps and 33,000 points of interest targeted at truck drivers and according to Cobra the industry’s best last-mile routing.  Read More

The WeGo integrates GPS satellite navigation and a HUD in an all-in-one design

Head-up displays (HUDs) first appeared on production vehicles way back in the late 1980’s, and add-on HUDs have been around for quite a while too - and not just for cars but also for motorbike helmets. But Taiwan-based Springteq says its WeGo HUD Navigator is the first product to integrate GPS satellite navigation and a HUD in an all-in-one design. The device projects navigation information onto the windshield to provide a virtual readout out that appears roughly one meter (3.3-feet) in front of the driver.  Read More

The TomTom GO LIVE 1000

TomTom today previewed a new generation of navigation devices designed to offer real-time services to drivers. The first example of the new generation is the GO LIVE 1000, which uses an ARM 11 500 Mhz processor and comes with several new features, including the ability to run downloadable third party apps, IQ Routes™ which applies historical travel time data to calculate the fastest route and HD Traffic™ which gives accurate real time traffic information for all major and secondary roads. The unit's software and service delivery platform have been optimised for rapid integration of third party applications and easy localisation to match the needs of specific markets or applications. The TomTom GO LIVE 1000 will be available mid year.  Read More

A simple two icon start screen should make navigating even easier

TomTom's EASE is the latest addition to its satellite navigation family and brings all the functionality, ease of use and practicality of its siblings at a fraction of the cost. Launched at CES in Las Vegas this week, the EASE blends a simple two icon interface menu, an integrated fold-away mount and the company's proprietary Map Share and IQ Routes - all for around a hundred US dollars.  Read More

EGNOS will enable new transport applications and track vehicles more accurately (Image Cre...

The European Commission has announced the official start of operations of the European Geostationary Navigation Overlay Service (EGNOS), a satellite based augmentation system (SBAS) that improves the accuracy of the current US Global Positioning System (GPS) and Russian GLONASS system signals from about ten meters to two meters. Like the U.S. GPS, the EGNOS Open Service is accessible free of charge to any user equipped with a GPS/SBAS compatible receiver within the EGNOS coverage area, which includes most European states and has the built-in capability to be extended to other regions, such as North Africa and EU neighboring countries. Most receivers sold today in Europe meet that requirement.  Read More
