Definitions
- the present invention relates to the positioning of a transceiver using other transceivers. It has particular application to the positioning of a transceiver by forming an ad hoc network of transceivers without the use of a dedicated infrastructure.
- GPS Global position system
- Cellular positioning systems have also been proposed in which the existing network of fixed base station transceivers is used to locate a mobile phone. The unchanging position and identity of the fixed base stations and the distance of the mobile phone from the base stations is used to estimate the phones location. Both of these systems operate over large distances exceeding many kilometres.
- the probability density function representing the position of the receiver Ti is therefore given by the convolution of the probability density function representing the position of the transmitter Ty ' with the probability density function representing the likelihood of successful transmission from the transmitter to receiver.
