Problems solved by technology
Among them, when geomagnetic orientation is used, it must be far away from the source of interference. If the environment is complex and the interference is too large, the measurement accuracy cannot be guaranteed, and the application is limited; the difference beam method requires four independent omnidirectional satellite navigation and positioning antennas. The directional method requires two omnidirectional satellite navigation and positioning antennas, and its system structure is complex

The invention discloses a single-antenna orientation method, which relates to the technical field of the Internet of Things and includes the following steps: half-blocking the antenna by using an occluder, wherein the signal reception of the antenna by the occluder forms a receiving effect of half the sky; obtaining satellites in the constellation The statistical direction of the vanishing zone in the figure; the direction of the antenna is deduced according to the statistical direction of the vanishing zone, wherein the statistical direction of the vanishing zone is obtained by a statistical method after observing multiple satellites for a period of time. The invention also provides a single-antenna directional device, which includes an antenna, a shielding component and a satellite positioning chip. When the single-antenna directional method of the present invention is applied statically, the direction of the object to be oriented can be deduced according to the installation relationship between the antenna pointing and the directional device and the object to be oriented. The invention is simple and easy to implement, can well realize static object orientation, and has good application advantages.
Description
technical field [0001] The present invention relates to the technical field of the Internet of Things, in particular to a single-antenna orientation method and device suitable for static applications. Background technique [0002] In static applications of the Internet of Things, orientation is a common requirement, such as orientation and attitude measurement of stationary objects, pointing measurement of stationary antennas, etc. There are three commonly used orientation methods: geomagnetic orientation, dual-antenna orientation method of satellite navigation signals and difference beam method. Among them, when geomagnetic orientation is used, it must be far away from the source of interference. If the environment is complex and the interference is too large, the measurement accuracy cannot be guaranteed, and the application is limited; the difference beam method requires four independent omnidirectional satellite navigation and positioning antennas. The orientation metho...
