Title: Sergey Nozdrachev: Innovator in GPS Technology
Introduction
Sergey Nozdrachev is a prominent inventor based in St. Petersburg, Russia. He has made significant contributions to the field of GPS technology, holding a total of 4 patents. His innovative work focuses on methods for improving signal acquisition and interference suppression in GPS receivers.
Latest Patents
One of Nozdrachev's latest patents is a method of weak signal acquisition and associated apparatus. This patent describes a GPS receiver architecture that utilizes digital correlation processing at a faster-than-real-time rate. The method involves storing signal samples in real-time at a first rate and reading them at a second, higher rate. To mitigate cross-correlation interference from strong signals, compensator blocks are introduced. Additionally, a method of interference waveform reproducing is disclosed, which compensates for the influence of stronger signals over long coherent accumulation intervals without complicating the processing of strong signals over shorter intervals.
Another notable patent is the method of cross-correlation and continuous wave interference suppression for GPS signals. This method provides a solution for processing weak indoor signals in the presence of interference. It includes generating a two-dimensional delay-Doppler accumulated power pattern and determining partial average values of accumulated powers to suppress the interference effect.
