PEMBANGUNAN SISTEM NAVIGASI OTOMATIS UNTUK MENDETEKSI SEDIMEN SUNGAI PADA PERAHU TANPA AWAK DENGAN MENGGUNAKAN GLOBAL POSITINING SYSTEM (GPS)

In this study, it discusses how to detect riverbed conditions that serve as information media that there is an increase in volume at the riverbed which results in flooding. The process of retrieving depth data using unmanned vessels, this ship is controlled using Ardupilot APM 2.6. Unmanned ships run to the designated waypoint point in square form automatically, because there is a GPS module that is connected to Ardupilot. the process of detecting conditions in the river using the MB7060 Sonar sensor. The sensor detects the area that has been traversed by unmanned vessels and then the data is stored automatically on the SD Memory Card. Data is moved on the laptop and the data is processed using the Surfer 13 application. The results of the data processing appear in figure 3 Contour dimensions on the river bed
