DSP High-Sensitive Tracking and Multipath Mitigation Algorithms

DSP High-Sensitive Tracking and Multipath Mitigation Algorithms

Client: manufacturer of high-performance GNSS devices

Scope: to develop and implement DSP high-sensitive tracking and multipath mitigation algorithms to improve competitive advantages of the GPS/GLONASS/etc. receivers in a strong shadowing condition

Project Features:

  • Mitigation of multipass to improve signal quality
  • Math algorithms for pulse gates switching
  • Exception of secondary tracking points
  • Discriminator curve development for better signal monitoring
  • Quasi-optimal algorithms implementation to reduce processor load
  • PLL, FLL and DLL tracking reliability significantly improved
  • Interface between Positioning Engine and the DSP part of the firmware was modificated
  • Availability of the measurements increased

Tools & Technologies: MatLab, C++, DSP
