This paper presents a brief survey of typical examples of systems in the field of position determination and identifies a need for a further research. This is followed by a description of a managed positioning environment for indoor and outdoor surroundings, in which accuracy and precision can be improved by using a mix of fixed sensors and the sensing capabilities of mobile devices in a way that it allows the transformation of proximity data into absolute coordinates. It is believed that this also improves the availability of the positioning service as partial, imprecise or incomplete data is utilised rather than discarded. The usage of wireless local area networks along with PDAs, mobile phones and similar devices, as opposed to custom sensors ensures that maintenance and administrative costs are kept to a minimum. Furthermore, a dynamic feedback system is proposed in order minimise deployment and initialisation effort by allowing refining of location information in fixed sensors.
