Embodiment Construction

[0027] The invention provides a wind measurement method based on GNSS autonomous speed measurement, without the assistance of an external augmentation system, and realizes autonomous speed measurement through a GNSS receiver. The present invention will be further described below in conjunction with the accompanying drawings.

[0028] Such as figure 1 As shown, the wind measuring device of the present invention includes a wind measuring platform (such as a drone), a carrier (such as a parachute), an antenna, a radio station and a GNSS receiver, and the wind measuring platform includes a computing device, an antenna, a radio station and a GNSS receiver The aircraft are all installed in the same box, and the box is installed on the parachute, and the installed parachute is dropped in the air at a certain height. When the parachute stabilizes for a period of time, it starts to land smoothly. At the same time, the GNSS receiver starts positioning and speed measurement; GNSS The re...

Abstract

The invention provides a wind measuring device and a wind measuring method based on GNSS autonomous speed measuring, and relates to the field of satellite navigation. The present invention uses a GNSS receiver for single-point speed measurement, and realizes the calculation and calculation of high-altitude wind speed, wind direction and wind profile through the obtained GNSS receiver single-point position information, speed information, and the relationship between wind speed and GNSS receiver speed information. Measurement. The present invention does not rely on external high-precision auxiliary equipment for wind measurement, which greatly reduces the complexity of the equipment and improves the measurement accuracy; at the same time, the present invention is simple in structure, practical, low in complexity, and has a wide range of application scenarios.

Description

technical field [0001] The invention relates to the field of satellite navigation, in particular to a device and method for measuring high-altitude wind speed, wind direction and wind profile based on GNSS autonomous speed measurement without the assistance of an external augmentation system. Background technique [0002] GPS wind measurement is a measurement system that was applied in the 1990s, and has now become an important means of atmospheric wind field measurement. The principle of GPS wind measurement is to use satellites to determine the wind direction and wind speed where the target is located by determining the position change of the freely moving target in the atmosphere. Since the GPS system can determine the target with high precision, theoretically, the accuracy of this wind measurement system is also high. At present, there are two methods of GPS technology wind measurement, one is Doppler frequency shift method, its accuracy is limited by the receiver; the ...
