The main focus of this research is to develop a real-time forest fire monitoring system using an Unmanned Aerial Vehicle (UAV). The UAV is equipped with sensors, a mini processor (Raspberry Pi) and Ardu Pilot Mega (APM) for the flight controller. This system used five sensors. The first is a temperature sensor that served to measure the temperature in the monitored forest area. The others sensors are embedded in the APM. There are a barometer, Global Positioning Sensor (GPS), inertial measurement unit (IMU) and compass sensor. GPS and compass are used in the navigation system. The barometer measured the air pressure that is used as a reference to maintain the height of the UAV. The IMU consists of accelerometer and gyroscope sensors that are used to estimate the vehicle position. The temperature data from the sensor and the data from GPS are processed by the Raspberry Pi 3, which serves as a mini processor. The results of the data processing are sent to the server to be accessible online and real-time on the website. The data transmission used the Transmission Control Protocol (TCP) system. The experimental setup was carried out in an area of 40 meters × 40 meters with 10 hotspots. The diameter of the hotspots is 0.4 meters with a height of 0.5 meters. The UAV is flown at a constant speed of 5 m/s at an altitude of 20 meters above the ground. The flight path is set by using a mission planner so the UAV can fly autonomously. The experimental results show that the system could detect seven hotspots in the first trial and nine hotspots in the second trial. This happened because there is some data loss in the transmission process. Other results indicate that the coordinates of hotspots detected by the UAV have a deviation error of approximately 1 meter from the actual fire point coordinates. This is still within the standard GPS accuracy as this system uses GPS with a range accuracy of 2.5 meters.

The main focus of this research is early detection system for forest fires by using Unmanned Aerial Vehicle (UAV). Data source of fires are collected by mobile devices such as GPS-equipped UAV quadcopter, non-contact infrared sensor, and the sensor stabilizer. The data from sensor is sent via telemetry link 433 Mhz, towards the Ground Control Station. Then the data is processed by a program that has been made, namely SPTA Real-time v0.1.0, which can show the temperature data as well as the color layer based on the difference of temperature levels in real-time on a digital map layer. The coordinates of fires are observed by SPTA realtime v0.1.0, and then it is compared with the coordinates of the source of the fire that is recorded manually. The results of data retrieval, the area that monitored is 3662 m2, constant height of 30 m, quadcopter speed of 5 m / s. First Data, with wind speeds of 3.2 m / s has a difference of 1.18 m from the coordinate source of the fire, within GPS tolerance accuracy is 2.5 m. For the second data with a wind speed of 6 m / s, has a difference of 5.16 m from the coordinates of the source of fire, deviated from the tolerance is 2.66 meter GPS accuracy.

Fighter Hand launch fixed wing

5334381699?profile=original

The fighter is a fixed-wing flight platform , which is easy to carry,friendly to operate,stable and durable.The fighter is positioned as a heavy-duty,long-endurance fixed wing,which greatly reduces the difficulty of aerial survey,further liberates productivity and improves the efficiency of aerial survey

The modular design concept makes the aircraft easy and fast to assemble.The wings,folding arms and tail fins can be easily dismantled, making the aircraft practical and portable and user-friendly.The open flight control cabin is compatible with Pixhawk flight control and supports mounting of Sony A7R2 4200W pixel full-frame camera /1.5kg lightweight lidar. The maximum support is 12s@22000mah lithium polymer battery,which can achieve ultra-long range and high-quality shooting effect

Using proper control point cooperatively,the final mapping would satisfy 1:1000 and 1:2000 aerial survey standard,which realized a wide-ranging application such as geography surveys,farmland,forestry land and grassland protection,power line inspection,environment protection,water conservancy and etc5334381900?profile=original

Study case : Drones against forest fire

Here is an example of how professional drones can help firefighters during forest fires. Airbot was engaged to provide a bird's eye view and crucial informations on burning surfaces and fire travel. The drone is one of the best tool for providing this kind of data and help the operations officer in his decisions and organization of ground resources.

Landing with strong wind using mRo x2.1-777

During some tests that we carried out autonomously of the mRo navigation systems, while we flew, the wind began to blow very hard and we decided to suspend the mission and land manually because the wind was increasing more and more and the gusts were erratic and unexpected.

To end the day, during the final approach the pilot made some low passes to be able to take some pictures of the plane from very close. Once the photos we achieved and we saw the circumstances complicated by the wind and the difficult landing, as fun we challenge the pilot to land with aim.

Due to the strong wind we couldn't land at the first attempt, so we had to abort the landing on several occasions repeating the same flight pattern.

At some moments during the final approach phase, we switch to “Stabilized” flight mode to check the safety that the mRo autopilot (mRo x2.1-777) brings while corrects the plane banking very quickly.

The video quality is not at all the best, because vibrations are shown on the camera and this is because it is mounted on a pan/tilt system.

Best regards
