research duties
Research Duties
  • Tracking/Evaluating European Geostationary Navigation Overlay System (EGNOS) in Warsaw
  • Comparing GPS accuracy with/without EGNOS
  • Comparing EGNOS with WAAS performance/accuracy/availability
    • Use real time data from:
      • Warsaw RIMS station
      • ESA EGNOS tracking sites
      • FAA WAAS website
  • Research with newly acquired Inertial Navigation/Measuring Unit (INU/IMU)
    • Analysis of an INS/GPS integrated system augmented with EGNOS
    • Reviewed over 100 different INU/IMU systems available for purchase
    • SRC acquired new Microbotics MIDG series INU/IMU based on my recommendation
research projects
Research Projects
  • Accuracy Analysis of the EGNOS System During Mobile Testing
    • Three months of test and evaluation of EGNOS system
      • Accuracy and availability during mobile testing
      • Complete report with detailed results presented to the Telecommunications Institute
  • Benefits of INS/GPS Integration
    • Integrated new INS into mobile testing lab
    • Simulated GPS signal loss to determine INS position accuracy over time
  • INS Signal Noise Analysis
    • Analyzing data from Allan Variance test
    • Determining Bias Instability and Random Walk for INS accelerometers and gyroscopes
  • WAAS vs EGNOS comparison analysis
    • Compiling data from various sources
    • Finalizing report and editing
egnos
EGNOS
  • Objectives
    • Check accuracy corrections of the EGNOS (PRN 126) system against GPS signals
    • Compare integrity and availability of GPS and EGNOS (PRN 126) signals

  • Conclusions:
  • Availability in Warsaw
    • Analyzing 10 days of static testing has shown EGNOS availability at 98% of the time
  • Accuracy in Warsaw
    • Overall, EGNOS improved accuracy
    • Inconsistent, during some observations EGNOS did not improve GPS accuracy
      • Receiver used less satellites with EGNOS (A minimum of three RIMS stations need to monitor the same GPS satellite to provide EGNOS corrections)
ins gps
INS/GPS
  • An inertial navigation system is a navigation aid that uses motion sensors to continuously track the position, orientation, and velocity (direction and speed of movement) of a vehicle without the need for external references
  • Benefits
    • INS complements GPS, aids in positioning solution in events of cycle slips and signal losses
    • Precise continuous positioning of a moving platform
  • Testing Objectives
    • Determine INS position accuracy during GPS signal loss
    • Determine if position accuracy improves with GPS+INS
ins gps18
INS/GPS
  • The MIDG II is a loosely coupled system
ins gps21
INS/GPS
  • Conclusions:
  • INS solution valid for about 20 seconds during GPS outages
  • INS + GPS did not significantly improve accuracy using the MIDG-INS, results varied
  • Y-axis for Nav was closer to kinematic solution than X-axis data
