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 and relates to the technical field of Internet of things, comprising the following steps of: partially shielding an antenna by an shield, wherein the shield forms a half receiving effect on the signal of the antenna; obtaining the statistical orientation of the disappearing band of satellites in the constellation; deriving the orientationof the antenna according to the statistical orientation of the disappearing band, wherein the statistical orientation of the disappearing band is obtained by a statistical method after observing a plurality of satellites for a period of time. The present invention also provides a single antenna orientation device comprising an antenna, a shielding component and a satellite positioning chip. Whenstatically applied, the single antenna orientation method can derive the orientation of an object to be oriented according to the installation relationship between an antenna pointing and orientationdevice and the object to be oriented. The single antenna orientation method is simple and easy to implement, can well achieve 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...
