Wheel-mounted MEMS IMU

Microelectromechanical systems (MEMS) play an essential role in automotive electronic control systems, providing measurements for tire pressure monitoring, vehicle stability control, adaptive suspension, rollover protection systems, and navigation systems. While MEMS gyros and accelerometers are suitable for vehicular applications in terms of size and cost, noise properties (large bias and signi cant 1/f noise) create problems, especially in low dynamic conditions or when measurements are integrated from angular rates to angles or from acceleration to velocity and position. GNSS receivers can complement these measurements but the availability and accuracy drops in urban canyons and underground.

Satellite Visibility to Aid Claus Mission

In lead position on a sleigh rising from the North Pole to a height of 200 meters — standard cruising altitude for global package delivery — at 2100 hours UTC on December 24 — the youngest will hopefully be asleep by then and there’s plenty of territory to cover before dawn breaks, time’s a-wasting — navigator Rudolph will see between 40 and 45 GNSS satellites glistening in the night sky.
