Abstract

Purpose

The Global Positioning System (GPS) is crucial for determining the positions of quadrotors, enabling safe flight and maintaining stability against environmental conditions. This study aims to investigate the effect of wind on the GPS of quadrotors experimentally.

Design/methodology/approach

This experimental study was conducted using an F450 frame, 980 kV motors and a Pixhawk flight controller to manage the quadrotor’s flight. To investigate the effects of wind on the quadrotor’s GPS during flight, a Pixhawk 4 Holybro flight controller was used. The experimental tests were performed on a predetermined route at different wind speeds.

Findings

Analysis of the data obtained from the flight tests showed that GPS signals were more affected as the wind speed increased. The percentage of GPS jamming levels reached 18% at high wind speeds.

Practical implications

Positioning services will be even more critical for quadrotors, which are expected to be used more frequently in public areas. This study is expected to be a reference for GPS-related research.

Originality/value

Winds pose a significant threat to the safe flight of quadrotors in many ways. This study experimentally investigates the effects of wind on the GPSs of quadrotors and to what extent it affects them at different wind speeds under real weather conditions. The obtained data shows that wind has a significant impact on GPS jamming.

Abstract

Purpose

The advancements in battery technologies, while trailing behind technological progress, face challenges meeting the soaring energy demands of quadrotors, resulting in flight durations that are far from satisfactory. Hence, this study aims to empirically investigate the impact of wind on battery consumption.

Design/methodology/approach

Flight tests were conducted using the Pixhawk 4 along identical flight paths and durations. In these flight tests, the quadrotor was exposed to different wind speeds.

Findings

The amount of energy consumed in the flight tests was examined. It has been observed that wind poses a serious threat to battery consumption and thus flight safety.

Practical implications

It is predicted that the data obtained from these studies will be useful in the battery and route selection of quadrotors used in many areas in the future.

Originality/value

This experimental investigation involved conducting numerous flight trials at diverse wind speeds under genuine atmospheric conditions. The energy consumption data acquired holds significance as it directly mirrors real-world scenarios encountered in practical applications.

Abstract

Purpose

Although windy weather conditions have a significant effect on the flight safety and stability of any aircraft, the fact that quadrotors are lighter than other aircraft makes them more sensitive to the wind. This study aims to examine the extent to which quadrotors and their sensors, which are used in many fields and whose use is expected to increase significantly in the future, are affected by wind.

Design/methodology/approach

Flight experiments were carried out on different routes assigned by using Pixhawk Holybro 4 and Radiolink flight controllers. In these flight experiments, quadrotors were exposed to winds at different speeds and directions.

Findings

In the flight experiments, the deviation amounts in the quadrotor’s route at which wind speed was determined, and it was seen that these deviations were very serious and affected the safe flight at high wind speeds. According to the sensor information obtained from both different quadrotors’ flight experiments at different wind speeds, it was determined that the wind decreased the sensors’ accuracy.

Practical implications

It is foreseen that the data obtained in this study will be a source to be used in the design of quadrotors to be used in public areas in the future and to take the wind into account for safe flight.

Originality/value

In this study, numerous flight tests were carried out experimentally at various speeds from low speeds to high speeds on different routes using different flight controllers. The deviation data on the obtained routes and the effect of the wind on the sensors are experienced in real atmospheric conditions.
