software multipath mitigation solution

We are making navigation more accurate in urban canyons

Evaluate GNSS ray tracing performance

  • Isolate LOS signal with multipath signals
  • Reflection and diffraction analysis
  • Identify multipath reflectors

Low cost reference system

  • Reference system when IMU is not easy to setup, e.g., running
  • Provide position, velocity, signal correlation map

GNSS signal analysis tool

  • Reliable multipath indication, LOS or multipath?
  • Raw measurements are available in RINEX format
  • Help debug tracking loop anomaly, e.g., which signal is tracked in your solution
