Problems solved by technology

Because the balloon used in this method drifts with the wind, it is not easy to detect the atmospheric parameters of a certain point in the high altitude
In addition, the radar has a limited range of action and cannot detect the atmospheric conditions over uninhabited areas deep in the ocean or desert

Embodiment Construction

[0006] For the stratospheric drop sounding system adopted in the embodiment, see figure 1 , consists of a high-altitude balloon 1, a main cable cutter 2, a parachute 3, an instrument cabin and a drop controller 4, a drop sonde 5, and a balloon ground station.

[0007] The high-altitude balloon adopts a zero-pressure balloon with a volume of 1,000 cubic meters, and its sphere is made of low-temperature-resistant high-strength polyethylene plastic film through hot-press welding. The upper part of the sphere is connected with the inflation pipe, and the lower part is connected with the exhaust pipe. The inflatable tube is tied up with ropes after the balloon has been filled with buoyant gas (hydrogen or helium) to make it airtight, and the exhaust tube is then communicated with the atmosphere. After the balloon is lifted into the air, as the altitude continues to increase, the buoyant gas gradually expands until it reaches the design volume. Zero pressure balloon. Because the ...

Abstract

A dropsonde system adopting a stratospheric balloon adopts the zero-pressure high altitude balloon to fly horizontally in the stratosphere according to the preset height, can adopt the actual situation of different wind directions in different height and adopt the means such as slinging, exhausting and the like to control the balloon to float to the target zone, and then throws the dropsonde down to detect the vertical profiles of the basic parameters such as atmospheric temperature, humidity, pressure, wind direction and speed and the like in the zone. In addition, the system also adopts the satellite relay communication technology and can detect the atmospheric condition over the sea or the uninhabited zones in deep desert.

Description

technical field [0001] The invention provides a stratospheric balloon drop sounding system, which relates to the fields of atmospheric detection technology, GPS application technology, satellite communication technology and radio technology. Background technique [0002] Atmospheric detection usually adopts the method of launching a detection balloon on the ground, tracking and receiving the radio signal sent by the radiosonde carried by the balloon with radar, and obtaining the vertical distribution of basic atmospheric parameters in a certain place. Because the balloon used in this method drifts with the wind, it is not easy to detect the atmospheric parameters of a certain point in the high altitude. Furthermore, the radar has a limited range of action and cannot detect the atmospheric conditions over uninhabited areas in the depths of the ocean or desert. Contents of the invention [0003] The drop sounding system provided by the present invention adopts a zero-pressu...
