Latest Patents

Muraki's latest patents include a "Receiving method and receiving apparatus" and an "Initial position determination method, positioning method, and positioning apparatus." The first patent describes a baseband process circuit unit that demodulates received satellite signals carrying navigation messages. It features an error bit detection unit that identifies errors in the demodulated data using a parity code. Additionally, an inconsistent bit detection unit compares the demodulated data with prescribed comparison data to identify inconsistencies. The adoption determination unit then decides whether to adopt the demodulated data based on the differences between the error and inconsistent bits. A correction unit is also included to correct the data if it is deemed adoptable.

The second patent outlines a method for determining an initial position during positioning calculations based on satellite signals. This method involves executing position converging calculations using multiple candidate positions, selecting at least one second candidate position based on the results, and ultimately determining the initial position from the selected candidates.
