ASSISTED SATELLITE SIGNAL BASED POSITIONING

摘要

For assisting a satellite based positioning, parameters are received for at least one satellite. Redundant information is removed from these parameters at large. Parameters with reduced redundancy are then provided as assistance data for the satellite signal based positioning. Such parameters with reduced redundancy can be received on the other hand as assistance data for a satellite signal based positioning. The original parameters are then reconstructed by adding the removed redundant information to the received parameters. The reconstructed original parameters are used in an assisted satellite signal based positioning.
