This article presents a simple solution to one of the main challenges of indoor pedestrian navigation.  Many researchers have shown the benefits of using low cost shoe mounted IMUs, but the major drawback of these systems is the rapid and dramatic growth in heading drift error.  The method...more >>

Low cost MEMS gyros and accelerometers are often considered as a potential solution for indoor navigation, but the reality is that such sensors are only sufficient to provide useful positioning for very short periods of time. This is due to sensor errors such as biases and scale factor errors that...more >>

Test results show improvements in the stability of the Network Real-Time Kinematic service when using fixed-IP SIM cards for long periods of observations, as well as high availability of the service with both types of SIM cards - better than 99 percent.

The UbiComp concept has spawned smart coffee pots, smart printers, smart copy machines and the like, all connected via a wired or wireless network. For a UbiComp device to know its position anywhere and anytime, we need ubiquitous positioning or UbiPos. This article looks at the available...more >>

Road User Charging (RUC) - also known as road pricing - reduces the pressure on urban or interurban road space by making drivers pay for using it.

Two of the greatest challenges for satellite positioning are poor skyview environment and high antenna dynamics. A team of researchers tackled both to create a 3-D map of a high-speed ice-sledding track. The task required them to use a hybrid GPS-Glonass receiver and to develop dedicated software.
