Introduction

Sergey Ivanovich Tychinskiy is a prominent inventor based in Moscow, Russia. He has made significant contributions to the field of GNSS technology, holding a total of 6 patents. His work focuses on enhancing the accuracy and functionality of GNSS receivers, which are crucial for various applications, including vehicle navigation and timing synchronization.

Latest Patents

Tychinskiy's latest patents include a GNSS-based attitude determination algorithm and a triple-antenna GNSS receiver for its implementation. The first patent addresses the determination of vehicle orientation based on GNSS signals received by three antennas that are logically combined into two pairs, with one antenna common for both pairs. This innovative approach allows for the measurement of the first carrier phase difference within each pair of antennas, which is represented as the sum of an integer number of periods of the carrier frequency and a fractional part of the period. The fractional parts are utilized to compute the orientation of the vector connecting the antennas' phase centers within each pair, effectively excluding integer ambiguity resolution. The vehicle's attitude is calculated from the orientation of two non-collinear vectors with a common origin, measured by two pairs of antennas, each equipped with an RF front end. All RF front ends, heterodynes, and digital navigation processors of this receiver are synchronized using a common clock oscillator, ensuring that all carrier phase measurements of the three antennas are performed on a unified time scale.

The second patent involves a GNSS timing receiver that synchronizes raw GNSS measurements to an external timescale. This synchronization is achieved through a hardware Time Interval Measurement Unit (TIMU), which measures time intervals between two pulse signals and processes these measurements. The first pulse signal is generated within the GNSS receiver, while the second pulse signal is produced by an external time reference device. This time interval is crucial for controlling the timing of output GNSS measurements. In one embodiment, all actual GNSS measurements are taken at time instants indicated by the external pulse signal, while in another embodiment, measurements are taken at their default time instants but are calculated at the time instants indicated by the external pulse signal.
