NemeriX, a Swiss fabless GPS semiconductor company, and Bosch Sensortec, a German supplier of MEMS (Micro Electro-Mechanical Systems) sensors for consumer markets, have announced the successful integration of their technology to deliver vertical accuracy to GPS, improving turn by turn navigation in multi level road systems environments.

With the technological progress made over the recent years in the MEMS industry, inertial sensors, pressure sensors and magnetic sensors are finding their ways into more consumer electronics products. In the navigation and positioning application industry they are coming to supplement the limitations of the GPS, embedded into portable devices.

The innovative solution integrates the high-resolution Bosch Sensortec SMD500 pressure sensor (altimeter and barometer in a very compact module) with NemeriX's GPS solution, offering the ability to identify if a vehicle is travelling on the upper or lower levels in a multi-level or stacked road. Indeed, even with high-performance GPS systems, typically the vertical accuracy that is achieved is significantly lower than the horizontal accuracy. This effect can be aggravated when the lower road is obstructed by the higher road, further degrading the vertical accuracy. This new solution enables the vertical performance to be significantly improved to the level where a typical road-to-road vertical distance of 10 meters or more can be unambiguously resolved.

The level of precision made possible by this technological partnership will be very interesting in the context of 3D navigation. The quality of the map data converging with the vertical accuracy will allow realistic 3D representations of complex highway interchanges, eliminating a large part of the guessing drivers are still facing today when confronted to a two dimensional representation of a multi level road on their navigation device.
