Modeling of DVL Sensor Error in Amphibious Aerial Vehicle (AAV)

Precise navigation in amphibious aerial vehicles presents multiple challenges due to their operation in both aerial and aquatic environments. One of the key factors affecting navigation accuracy is the error in velocity measurement sensors, which can be influenced by noise, environmental conditions, and improper calibration. In this study, a simulation model is developed to analyze the error of the Doppler Velocity Log (DVL) sensor in amphibious aerial vehicles. First, various error sources are identified and modeled, and then their impact on navigation performance is evaluated through numerical simulations. Additionally, a filtering process is applied to the sensor signals to enhance the accuracy of the output data. The results indicate that some errors can be compensated, and the proposed model can contribute to improving navigation accuracy in amphibious aerial vehicles equipped with DVL. By the results, despite all the introduced errors, the sensor model shows approximately ±۹.۵۱% error at velocity vector determination.
