kalman.js is a simple Kalman Filter library that allows you to apply the popular filter on any set of data.
To use the Kalman Filter, you simply create a new object:
var filter = new KalmanFilter(0.02,3,10);
And then you can proceed to input measurements to get the filtered result:
var filteredX = filter.update(x);
To download using npm simply use the command:
npm install kalmanjs
We have added an example that uses google maps and angular to simulate using a kalman filter on gps signals
