Patent number: 11942948Abstract: An apparatus for forming wideband pseudo random noise signals includes a set of channels each comprising an NCO having a controlled frequency and phase and a PRN code generator, the NCO generating a strobe that is output to the PRN code generator. The PRN code generator forms a new sequence element of +1 or ?1 in response to the strobe. The apparatus also comprises a first modulator having a plurality of weight coefficients, a plurality of multipliers each multiplying one of the weight coefficients, an adder outputting a sum of the plurality of multipliers output signals, and a mixer with a quadrature output signal multiplying the adder's output by sine and cosine of a low intermediate frequency. The apparatus also includes a processor controlling the set of channels, a transceiver module to receive and/or transmit quadrature signals, and an interface connecting the output of the mixer and the transceiver module.Type: GrantFiled: October 8, 2021Date of Patent: March 26, 2024Assignee: TOPCON POSITIONING SYSTEMS, INC.Inventors: Leonid Victorovich Purto, Sergey Sayarovich Bogoutdinov, Dmitry Anatolyevich Rubtsov

Publication number: 20230384458Abstract: An apparatus includes an antenna, RF path, Analog to Digital convertor (ADC), filter, and navigation channel for processing a received GNSS signal based on a navigation clock. A communication modem is configured to receive the signal via a first antenna, RF path, and ADC and process the received signal in order to generate a signal based on a modem clock. The communication modem is further configured to transmit the signal based on the modem clock using a R+1 antenna via a R+1 RF path and a Digital to Analog Convertor (DAC). A multichannel synchronous signal analysis system (MSSAS) receives outputs of the ADCs and processes them using a plurality of decimators and plurality data receivers. Each of the decimators is configured to process the outputs of the ADCs and output data to one of a plurality of data receivers. A CPU is configured to control all of the devices.Type: ApplicationFiled: October 11, 2021Publication date: November 30, 2023Applicant: Topcon Positioning Systems, Inc.Inventors: Sergey Sayarovich BOGOUTDINOV, Fedor Borisovich SERKIN, Andrey Vladimirovich VEITSEL, Dmitry Yuryevich GOLDBERG, Dmitry Anatolyevich RUBTSOV
