NTP SERVER DESIGN AS A TIME DIFFERENCE MITIGATION AT PERUM LPPNPI KENDARI BRANCH

Abstract

In the world of aviation, it takes the right time, time synchronization is very important for the aviation system. If the time of the flight telecommunication facility is out of sync or out of sync, the flight data will be chaotic, so it is not known when the aircraft will land. If the time is not synchronized, data on accident incidents will be difficult to find. This research method uses an ESP32 Microcontroller connected to the NTP Server through internet media, then the NTP Server generates time data in the form of UTC (Coordinate Universal Time) time. The ESP32 microcontroller functions as a server on the device that will perform time synchronization, and the NTP Server data has accurate time accuracy. In the event of a time shift it will be compensated by the ESP32 Microcontroller.
