  • Patent number: 10690779
    Abstract: A baseband tracking channel in a GNSS receiver is provided. The baseband tracking channel comprises: a code generator to generate a local signal correlating with an incoming signal received by the GNSS receiver; a multiplier that multiplies the local signal with a baseband signal corresponding to an incoming signal received by the GNSS receiver to generate a code removed signal; a prompt correlator including at least one integration register that integrates samples of the code removed signal corresponding to a first portion of each pseudorandom noise code chip of the code removed signal to provide a first integration register output, and integrates samples corresponding to a second portion of each PRN code chip to provide a second integration register output; and a side peak tracking detection module that generates information indicating when side peak tracking is occurring based on the first integration register output and the second integration register output.

  • Patent number: 10663600
    Abstract: A method of global navigation satellite system (GNSS) acquisition comprises: computing a line of sight (LOS) angle between a LOS vector of a first satellite and a LOS vector of a second satellite, wherein each LOS vector is the LOS vector between a receiver and the respective satellite; computing a maximum Doppler difference, wherein the maximum Doppler difference is computed between the first satellite and the second satellite based on the LOS angle and a maximum velocity vector attainable by the receiver, wherein Doppler is induced at least by movement of the receiver; determining a final frequency search range based on the maximum Doppler difference computed between the first satellite and the second satellite, wherein the frequency search range includes a center frequency equal to the first frequency at which the first satellite is found; acquiring a GNSS signal from the second satellite at a second frequency.
