Title: Akira Kimura: Innovator in Satellite Positioning Systems
Introduction
Akira Kimura is a notable inventor based in San Francisco, CA, who has made significant contributions to the field of satellite positioning systems. With a total of 3 patents to his name, Kimura's work focuses on enhancing the accuracy and efficiency of satellite navigation technology.
Latest Patents
One of Kimura's latest patents is for a synthetic NAV-data system designed for high-sensitivity satellite positioning system (SPS) receivers. This innovative SPS receiver includes a radio receiver that measures pseudoranges to orbiting SPS satellites, a local real-time clock that maintains accuracy within three seconds of true SPS system time, and a communication channel for receiving NAV-data rebroadcasts from a server. The server is linked to a private navigation receiver capable of strong satellite signal reception, allowing the SPS receiver to synthesize its own NAV-data from time information and almanac and ephemeris data provided by the server. This advancement enables the SPS receiver to function effectively in weak signal environments.
Another significant patent by Kimura addresses the issue of preamble frame synchronization in navigation-satellite receivers. This technology utilizes a reference station accessible over a network to store NAV data subframes for pattern matching at a network client. In scenarios where per-byte communication costs are high, the server can perform the pattern matching. The stored NAV data repeats ephemeris data every thirty seconds and full almanac data every 12.5 minutes, allowing the client to quickly identify its position within the NAV data sequence without waiting for preambles in the TLM words. This innovation significantly reduces the time required to achieve a rapid time-to-first-fix.
