1. Overview

This page describes the circle selection algorithm while calculating results from the Apollonius (AP) method. Details of the AP method can be found here.

2. Objective

The AP method provides multiple results (in the form of a solution set) when calculating the target location using RTT measurements from landmarks. At the moment we manually select the most appropriate result (by comparing the results with geo-ip results). We need to devise a method of selecting the most suitable results among those calculated by the AP algorithm.

In certain cases the AP method does not return any result. In that scenario we change the landmarks used to calculate the results. The algorithm that does so is explained here.
