Title: Innovations by Lance De Groot
Introduction
Lance De Groot is a notable inventor based in Calgary, Canada. He has made significant contributions to the field of GNSS technology, holding three patents that showcase his expertise and innovative spirit. His work focuses on enhancing the accuracy and reliability of navigation systems.
Latest Patents
One of Lance De Groot's latest patents is a system and method for calculating protection levels for velocity and course over ground. In this embodiment, a GNSS receiver calculates protection levels for velocity and course over ground. The GNSS receiver obtains Doppler measurements and variance measurements based on satellite signals received from at least five GNSS satellites. It utilizes a least squares method to calculate the velocity states, including x-velocity state, y-velocity state, and z-velocity state, along with the clock bias for the GNSS receiver. The receiver calculates the slope for each Doppler measurement on each velocity state. It then selects the maximum slope for each velocity state and scales up the maximum slopes by a non-centrality parameter to calculate the protection level for each velocity state in the ECEF frame. Finally, the GNSS receiver converts the velocity protection levels to NEU velocity protection levels to calculate a protection level for course over ground.
