Abstract—As the human pays more and more attention to the exploration of marine resources, the marine activities show diversity. At the aspect of the exploration of some uncharted and potentially dangerous waters or islands, the marine low altitude surveillance UAV (unmanned aerial vehicle) is obviously very important. As a tool to obtain first-hand information, UAV can take off near the monitored area. Carrying with a high-definition camera, altimeter, GPS, barometric pressure and humidity sensors, the UAV can monitor the area for real-time, get the latitude and longitude of specific landmarks, measure altitude and barometric pressure and humidity and etc. Therefore we can have a general understanding of the whole area to eliminate risk factors. In addition, for different application environments, UAV can be equipped with different monitoring devices, which makes the application for more flexible and the areas for more diversity.

I.I NTRODUCTION

With the national marine economy being proposed, the low-altitude UAV remote sensing is applied to marine monitoring and monitors marine emergencies, marine disasters, marine environment dynamically with real-time tracking, to provide real-time field data for the marine forecasters for Rapid Alert and a scientific basis of decisions and solution for the marine management. Regardless of the protection of the marine disaster prevention and mitigation services and the need for the development of national high- tech, it is urgent to develop the real-time monitoring system of the marine environment with quick response and intensification and establish the report of efficient disaster warning service on the basis of new technology.

Low-altitude UAV remote sensing marine monitoring as an monitoring technology of important and in the initial stage, on one hand, can do emergency response, without waiting for satellite transit or the limit of flying height of traditional aviation Airborne remote sensing; On the other hand, can overcome the defects of the optical remote sensing technology of traditional satellite in South cloudy and rainy weather and will greatly enhance the ability of monitoring Marine dynamically and urgently monitoring of disaster prevention and maneuver reduction, which provides quality services to the marine disaster prevention and mitigation, then escorts for the economic development of regional marine.

This article will focus on UAV low altitude marine monitoring system with Art-tech Diamond 2500 Glider unmanned marine as the hardware platform, then describe the consist, the key technology and its applications of system.

II.T HE C OMPOSITION OF S YSTEM

UAV low-altitude Marine monitoring system consists of ground flight control system, aerial surveillance flight system, UAV driving flying platform, wireless HD video transmission system and so on.

A.Ground Flight Control System

Ground flight control systems is useful for the flight control of UAV and the processing and display of related data, including data transceiver module, debug interface, gesture controller(as shown in Fig.1). By the composition of wireless module, JTAG interface, the control handle, STM32 controller, PC terminal, it can be achieved on the UAV attitude, altitude, speed, heading, route control, with remote control and autonomous flight modes.

In order to improve the reliability of the flight control system, the system uses the wireless transceiver module with a high transmission rate and low error rate to ensure that the control signals can be transmitted in real -time and received correctly. Because digital connection being instead of analog, which improves the accuracy of signal transmission and increases the anti-jamming capability. The body has the ability to be extended and flexible configuration, and some typical system components may be changed according to the needs of the missions.

B.Aerial Surveillance Flight System

Aerial surveillance flight system is response to the control signal of ground flight control system. It adjusts the flight of the UAV in real-time and collects relevant data information by a variety of sensors, which includes three parts of sensors, actuators and flight controller (as shown in Fig.2). By the composition of GPS module, battery voltage detection module, altimeter, barometer and humidity detection module, wireless module, attitude acquisition module, STM32 controllers, actuators, it can measure the location latitude and longitude, altitude, barometric pressure and humidity, life
