Problems solved by technology

[0003] However, most of the positioning technologies only provide the location information of the user in two-dimensional space. Users often cannot clearly know their current location and the direction they should travel through the two-dimensional positioning information. When the driver is in an unfamiliar environment , two-dimensional positioning information cannot provide effective guidance

Abstract

The invention relates to a method and device for calculating an attitude angle. The method includes the steps of detecting a satellite signal by using a first antenna array to obtain a plurality of first input signals, detecting the satellite signal by using a second antenna array to obtain a plurality of second input signals, performing a phase operation according to the plurality of first input signals to generate a plurality of first output signals, performing phase operation according to the plurality of second input signals to generate a plurality of second output signals, obtaining a relative attitude angle according to the plurality of first output signals and the plurality of second output signals, obtaining an absolute attitude angle from the satellite signal, and generating an actual attitude angle of a vehicle based on the absolute attitude angle and the relative attitude angle. With the method and device of the attitude angle of the invention, the actual attitude angle of the antenna in a three-dimensional space is generated by the absolute attitude angle of a GPS satellite with respect to the ground and the relative attitude angle of the GPS satellite with respect to the two antenna arrays, and thus more precise positioning information is provided.

Description

【Technical field】 [0001] The present invention relates to an antenna module and a positioning method using the same, especially a method and a device for calculating an attitude angle. 【Background technique】 [0002] Global Positioning System (GPS) is a positioning technology that combines satellite and wireless communication, which can provide precise positioning, speed and time information. The GPS can be combined with an electronic map, and the positioning information obtained by the GPS can be displayed on the electronic map, so as to provide users with an understanding of their current location. Furthermore, with the maturity of the navigation system technology, the positioning technology combined with the navigation system is applied to mobile phones, computers and various means of transportation, etc., and its application scope is increasingly extensive, which brings considerable convenience to human life. [0003] However, most of the positioning technologies only p...
