I want to find the coordinate of an unknown node which lie somewhere in the space which has its reference distance away from 3 or more nodes which all of them have known coordinate. This problem i...

I am having some trouble to find or implement an algorithm to find a signal source. The objective of my work is to find the sound emitter position. To accomplish this I am using three microfones. ...

I've been struggling for a while with this, I'm currently using Estimote Beacon on Android and I'm collecting their RSSI and TxPower to calculate their range. Once I got this data and I know their ...

I am having some trouble to find or implement an algorithm to find a signal source. The objective of my work is to find the sound emitter position. To accomplish this I am using three vibration se...

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 ada...

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 recei...

I am trying to create an android smartphone application which uses Apples iBeacon technology to determine the current indoor location of itself. I already managed to get all available beacons and c...

I have a little problem... Does anyone knows about how can i implement this? I need a method in java like this: public /*COORDINATE OBJECT*/ getTrilaterationPointBetween( /*COORDINATE OBJECT*/ co...

Assume that we have 4 points in 3-D (P1, P2, P3, P4). If the coordinates of those points are given with their euclidian distances to a fifth point P5 (r1, r2, r3, r4), how to calculate the coordina...

I'm working on how to determine distance with the Wi-Fi signal strength, from this article: Indoor Position Detection Using Wi-Fi and Trilateration Technique. How can I do this method? What is the...

I start working in an android application that determin the position with the WI-FI Signal Strength.well i read a lot of theses and every time a found a new idea and new concepts ,and that made me ...

I'm a student at the University of Furtwangen in Germany. I am in my final term and I am writing my thesis now. I'm very interested in iBeacons and the technology behind them. My current project i...

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 ...

I am writing some code to participate in an AI challenge. The main objective for the AI challenge is to take a simulated robot and navigate it through a maze to a destination zone. The secondary ob...

first question to StackOverflow, please be gentle. I am trying to find the equation (and then the algorithm for) the center point of three different points on a 2D cartesian plane, given a certai...

There exists an unknown target location (latitude and longitude co-ordinates). I have 3 latitude and longitude co-ordinate pairs and for each pair a distance in kilometers to the target location. H...
