Abstract
A tentative location of a transmitter in an indoor environment is determined by triangulation, using at least two direction finders. The tentative location is made more accurate by performing at least one added action selected from the following: checking the likelihood that the tentative location is an accurate location by comparing measured transmitter signal strengths with calculated signal strengths, using a known indoor environment structure, using a record of the transmitter movement through the indoor environment for determining whether the transmitter is located in an obscured area of the indoor environment or performing an alignment procedure on the antennas to improve the triangulation.
