Data acquisition unit for road vehicle or aircraft

Abstract

Data acquisition is a critical aspect of modern vehicle and aircraft design, as it provides engineers and researchers with essential information on the performance and behaviour of these vehicles in various operating conditions. In this paper, we present a data acquisition unit (DAU) for road vehicle or aircraft that utilizes various sensors, including GNSS, INS, RPM measurement, barometric altimeter, and ESP32 microcontroller. The DAU consists of multiple sensors, including a GNSS receiver to determine the vehicle's position, speed, and heading. An inertial navigation system (INS) is used to measure the vehicle's acceleration and angular rate. RPM sensors are used to measure engine speed, and a barometric altimeter is used to measure the altitude of the vehicle. An ESP32 microcontroller is used to acquire, process, and store the data from these sensors. In the end the design and utilisation of DAU was success gaining data for research in field of road and air transport.
