Problems solved by technology

[0003] Although the LAMBDA algorithm is fast and real-time, it does not have a verification mechanism for the selected integer ambiguity, and the basis for determining the ambiguity is single, resulting in search failures when performing an integer ambiguity search, especially When the observation conditions are not good, the probability of search failure is higher
Therefore, the position monitoring of the target based on the LAMBDA algorithm cannot bring better monitoring results.

Abstract

The embodiment of the present invention discloses a position monitoring method, the method includes: using the preset pseudo-range double-difference equation and the preset carrier double-difference equation to perform double-difference integer ambiguity search to obtain the first residual value, The second residual value and the first double-difference integer solution of N groups; threshold, then use a set of first double-difference integer solutions in the N groups to carry out a full-field search on the carrier double-difference equation to obtain a set of first baseline vectors; if the set of first baseline vectors satisfies the predetermined If the constraint condition is set, it is determined that the position of the monitoring target has not moved. In addition, the embodiment of the invention also discloses a position monitoring device, equipment and storage medium.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and relate to, but are not limited to, a location monitoring method, device, equipment, and storage medium. Background technique [0002] When monitoring the position of a target, it is usually determined whether the target moves through positioning technology. For high-precision satellite navigation and positioning, the most important calculation is the search of the ambiguity of the satellite carrier phase observations. The general search technique is the Least-square Ambiguity Decorrelation Adjustment method. LAMBDA). The LAMBDA algorithm is a fast double-difference integer ambiguity solution method, which specifies a search space for the integer solutions of the integer ambiguity, and obtains a group with the smallest error in this search space as the only solution for high-precision solution. [0003] Although the LAMBDA algorithm is fast and real-time, it does not have a...
