How to map in real time using indoor beacons on Android? Did tests using the SDK Estimote however, they do not have support for Android in indoor and do not have a method that returns the distance to the beacon. With that, I'm using Alt SDK that returns me the distance. But not her how to solve these doubts: 1) create a map (2D or 3D Google Maps type) with the location map of the inside of a room or shop for example. 2) show the location of the user's route to the beacon. 3) how to deal with the route to the beacon avoiding collision enters walls on the map? 4) how to locate the user's

I'm trying to implement a trilateration algorithm into my Android app to determine a user's indoor location. I'm using ultra-wideband beacons to get the distances to fixed points. I was able to adapt the method suggested in Trilateration Method Android Java as follows: public LatLng getLocationByTrilateration( LatLng location1, double distance1, LatLng location2, double distance2, LatLng location3, double distance3){ //DECLARE VARIABLES double[] P1 = new double[2]; double[] P2 = new double[2]; double[] P3 = new double[2]; double[] ex = new double[2]; double[] ey = new double[2]; double[] p3p1

I want to design an Android application which can help students and others navigate their way around a particular building(with one floor) showing walking directions to classrooms. I need help with it. This is the kind of project you normally develop for your thesis. It is much larger and more complex of what it can look at a first glance. Googling around you will find a lot of BCS and master thesis on this topic. Read them and you will find almost all the information you need to develop your own system. As a starting point you can use redpin: http://redpin.org/ . While Google Maps can

Well for triangulation you need to have the direction from which your device is receiving the signal.We can calculate Angle of Arrival for that but calculating that angle requires an array of receivers. Is a cell phone capable of calculating Angle of Arrival? I am asking this because I have came across the terms like wifi/BLE triangulation, calculating position by triangulation etc but they're actually referring to Trilateration in most of the cases. I know how trilateration works for a mobile and all the details but I don't think Triangulation is possible. And if it is possible, how is it

I should be developing an indoor positioning system for some place , so I started by gathering info about how to develop such a system , the question I am up to now is : what controls the accuracy of positioning and how to improve it ? I found different APIs and projects with various accuracies , for example : ericsson indoor positioning API provides an accuracy within 10 meters , while Qubulus API provides an accuracy within 4 meters , and I met some projects like iDOCNET which claims to provide an accuracy of about 1.2 meters. So, what is the main component of the indoor navigating systems
