Features:
  • Android-based GNSS / IMU logger

  • First Logger Capable of Logging RINEX and IMU data from the smartphone

    • Capable of logging

       - RINEX 3.03 with dual frequency and multi constellation

       - GNSS raw measurements

       - IMU data (accelerometer, gyroscope, and magnetometer)

       - Time Synchronized GNSS / IMU data to be directly used in GNSS / IMU Fusion
