Problems solved by technology

[0007] In the actual operation process, the tip of the centering rod is pressed against the measured point, and the operator continuously adjusts the angle of the centering rod according to the position of the bubble to keep the centering rod perpendicular to the horizontal plane. This adjustment needs to be continued during the terminal positioning process. , thus significantly increasing the workload

Abstract

The invention provides a hand-held terminal of global navigation satellites system and a centering and levelling method of the hand-held terminal without using a centering rod. The hand-held terminal comprises a shell body, a display screen which is arranged on the front of the shell body, and the shell body which is provided with a satellites antenna. The back of the shell body is provided with a laser designator and a camera, wherein the laser designator is used for issuing light beams to ground to form light-spots, and the camera is used for shooting images of measured points and the light-spots. In addition, an attitude sensor is arranged inside the shell body, and the attitude sensor is used for sensing a pitch angle and a roll angle of the satellites antenna. The display screen, the laser designator, the camera and the attitude sensor are connected to a main control panel which is arranged inside the shell body.

Description

technical field [0001] The present invention relates to a global navigation satellite system (Global navigation Satellites System, GNSS), in particular to a GNSS handheld terminal. Background technique [0002] GNSS is the general term for satellite navigation systems, which can be divided into global systems, regional systems, and augmentation systems. Global systems include the GPS system of the United States, the GLONASS system of Russia, the Galileo system of Europe, the Beidou system of China, the DORIS satellite-based radio Doppler orbit determination system of France, the PRARE satellite station distance and distance change rate measurement system of Germany, etc. . Regional systems include: Japan's QZSS quasi-zenith satellite system, India's IRNSS regional satellite navigation system, etc. Augmentation systems include: STARFIRE global space-based differential system, WAAS wide-area augmentation system, EGNOS European wide-area augmentation system, Japan's MSAS augm...
