摘要：

We demonstrate a low-cost, low-power, and small form factor solution to drift-free high-resolution vertical positioning by fusing MEMS accelerometers with MEMS barometric the highly responsive but drift-prone aspect of the MEMS accelerometers Is stabilized by barometric altimeter and high-fidelity height tracking Is achieved. Typical vertical human movements such as walking up or down a staircase can be tracked In real-time with this system The height tracking performance Is benchmarked against a reference system using a tactical-grade IMU and an error analysis Is performed.
