Today most commercial receivers are GPS L1 C/A code only. However, for many applications, the single frequency GPS performance is inadequate and many technology developers are turning to other sensors to compliment GPS. Today we have many forms and functions, depending on the application and hence needs. Integrated in-vehicle navigation systems often compliment the GPS position with dead reckoning navigation information from wheel rotation sensors. Often these are the same sensors used...

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...
