Abstract
Positioning data generated by the positioning module of a portable device is received. The positioning data was generated using signals received at the portable receiver from respective signal sources (such as satellites). Positioning data generated by one or more non-surveyed devices is also received. The positioning data from the one or more non-surveyed devices has a high degree of reliability as compared with the position data from the portable device. The highly reliable positioning data from the one or more non-surveyed devices is further processed to develop positioning corrections for the portable device.
