We have updated the INS + GPS White Paper with more details to further answer DCS: F-16C pilot questions.
Key highlights include:
INS Functionality: Understanding how the INS performs dead reckoning using accelerometers and gyros, and how errors such as Schuler Oscillation can affect navigation over time.
GPS Insights: Examines how GPS measures aircraft position, the challenges posed by ionospheric delay and multipath effects, and the advantages of military GPS signals.
Kalman Filtering: Understanding how the Kalman filter optimally blends INS and GPS data, enhancing navigation precision while maintaining autonomy against potential GPS discrepancies or spoofing.
Practical Applications: Learning about the INS FIX procedure to correct accumulated errors, especially when GPS is unavailable or after poor alignment, and the importance of using aircraft sensors for target acquisition to ensure maximum accuracy.
