Abstract: Navigation errors is one of the causes in Unmanned Aircraft System (UAS) positioning inaccuracy. In urban environment operations, multipath could be a dominant source to navigation errors. This paper presents a study on how the operation environment affects the lateral (horizontal) navigation performance when self-built UAS is going near vicinity to different type of urban obstructions in real flight tests. Test sites selected are representative to urban environment, i.e., which includes open space with a few short trees, near a conventional building, surrounded by buildings, and constraint area by buildings and tall trees. The data will be analysed using covariance to obtain the horizontal position error (EPH) with considerations for (i) Number of visible satellites versus flight altitude, (ii) Horizontal position errors at various locations in terms of precision and accuracy by comparing reported position and actual position, and (iii) Factors affecting the positional errors at various locations.
