With a total of five patents to his name, Yang has developed innovative methods that enhance the accuracy and efficiency of satellite-based navigation systems.
Latest Patents
One of Yang's latest patents is titled "GPS navigation using successive differences of carrier-phase measurements." This invention outlines a process for navigating an object by utilizing signals from satellites. The method involves propagating the object's position forward in time using successive changes in carrier-phase measurements. It computes matrices required for solving the object's position at a low rate and uses these matrices to compute position updates at a high rate until the next low-rate computation is completed.
Another notable patent is the "Method for combined use of a local RTK system and a regional, wide-area, or global carrier-phase positioning system." This invention presents a method that combines local RTK systems with regional or global differential carrier-phase positioning systems. It addresses the disadvantages of using RTK and WADGPS navigation techniques separately. The method initializes floating ambiguity values in the WADGPS system using a known position of a stationary user receiver or an RTK system when the user receiver is in motion.
