Embodiment Construction

[0026] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0027] see figure 1 with figure 2 , the present invention judges the method for whether base station receiver moves comprises the following steps:

[0028] 1S1. Receive satellite signals, process the satellite signals to obtain a positioning result of an epoch and a difference between positioning results between adjacent epochs, and the base station receiver also generates differential data.

[0029] In this step, how the base station receiver generates differential data belongs to the prior art, and will not be repeated here. The base station receiver can also use RTK or PPP technology to process satellite signals to obtain epoch positioning results, but this method requires external equipment to input data to the base station receiver...

Abstract

The invention discloses an OEM board, a receiver and a method for judging whether the base station receiver is moving. The method includes: S1, receiving satellite signals, processing the satellite signals to obtain the positioning result of an epoch and the difference between the positioning results between adjacent epochs, and the base station receiver also generates differential data; S2, judging the difference value is greater than the threshold, in the case of the difference greater than the threshold, the base station receiver generates an alarm signal and sends the alarm signal outward, in the case of the difference is not greater than the threshold, the base station receives The machine sends differential data to the outside. The invention can accurately judge whether the reference station receiver is moved with few devices.

Description

technical field [0001] The invention relates to the field of high-precision navigation (GNSS), in particular to a method for judging whether a reference station receiver is moving, an OEM board and a receiver with the OEM board. Background technique [0002] In the prior art, devices for realizing high-precision navigation usually include a base station and a mobile station. The base station receives satellite signals and solves satellite signals to obtain differential data, including base station receivers and related accessories. These differential data are sent to the mobile station through the network or the radio station. The mobile station obtains position information of the mobile station based on the differential data and the received satellite signal. In this way, its positioning accuracy can reach centimeter level. [0003] In the above method, the receiver of the base station is required to keep a static state during the measurement process. However, since the ...
