After doing many road tests in different platform such as ios(IPhone5s, IPhone6s, IPhone7) and android(HUAWEI, Honor, XiaoMi, VIVO, OPPO, SAMSUNG), we think it's now stable enough to operate in a variety of environments.

In this release, we did the following:

  1. According to different mobile phone platforms, the sensor data are extracted and converted into the input required by the system.
  2. The strapdown inertial navigation theory is adopted as the system foundation.
  3. Using the Kalman filter and the IIR-LPF to correct the GPS and sensor data.
  4. Optimizing for various practical scenarios.

Next release, we will do the following:

  1. Weak GPS can be used as a reference to some extent.
  2. Solve the comparison between directional fluctuation and off-course using Energy Statistics(may be).
  3. Solve the problem of inaccurate direction of low-speed GPS.
