A multiple content message (MCM) base apparatus configured to generate a composite base data stream is proposed. A multiple content message (MCM) rover apparatus configured to generate a set of fast frequency baseline data is proposed.

Multiple content message base-rover architecture

Methods and apparatus are presented for determining position a GNSS rover antenna from single-frequency observations of GNSS signals collected at the antenna over multiple epochs and from correction data for at least one of the epochs. Coded raw data prepared from the single-frequency observations in a binary format are obtained and decoded to obtain decoded raw data. The decoded raw data are used to construct multiple epochs of measurement data of time, range and phase. Correction data are obtained for at least one of the epochs. The measurement data are processed with the correction data in a realtime kinematic positioning engine to obtain a position estimate for each of a plurality of epochs.
