Abstract
A signal conversion device that provides RTCM correction data to a position determination device. The signal conversion device receives RTCM signals that are converted into a frequency adapted to be received by a position determination device so as to produce a converted correction signal. In one embodiment, the signal conversion device also converts the received RTCM correction data into a format that is adapted to be received by the position determination device. In one embodiment, the received RTCM signal is converted into is the Wide Area Augmentation System (WAAS) format. Alternatively, the signal is converted into a different format such as a particular manufacturer's own format. The converted correction signal is coupled to a position determination device via a wireless link. The position determination device uses the RTCM correction data contained in the converted correction signal for accurately determining position.
