One of the simplest and most popular ways of improving the accuracy of navigation systems is to combine GNSS-based navigation with inertial navigation using MEMS sensors. But what are they? MEMS stands for micro-electromechanical systems, and MEMS sensors comprise a class of devices that are micromachined from bulk silicon. As they are made from silicon, it’s possible to produce devices such as accelerometers that combine both a sensing element and the associated signal conditioning ci...

We are generally being encouraged through government sponsored advertising to spend less time in our cars or not to rev our car engines too much. By doing so we can help to save fuel, the world’s resources and, by implication, do our bit towards reducing climate change. The European Union has a long-standing target for car manufacturers to reduce average CO2 emissions for their vehicles to 120g/km by 2012. A longer term target is 80g/km by 2020. The view of the industry has been that this is...

Many world governments have a long-standing target for car manufacturers to reduce average CO2 emissions for their vehicles. The European Union target is 120g/km by 2012 and longer term to 80g/km by 2020. The view of the industry has been that this is very challenging and unlikely to be met via conventional approaches alone. Indeed, the 2012 target already represents a slip from an original 2005 target date. As most manufacturers will not be able to meet the 2012 target, further slippages (p...
