Problems solved by technology

However, in some high mountains, densely built or remote areas, the GPS signal frequency band cannot fully provide
In addition, the current logistics positioning only feeds back the location information to the customer when the goods arrive at a fixed station, but the dynamics of the goods on the way cannot be fed back to the customers, so the consulting cost about the dynamics of the goods will increase, and customers cannot Reasonable arrangement of time will reduce satisfaction with shopping

Abstract

The invention discloses a positioning method based on frequency band combination of a positioning system. The method includes: determining a set of candidate frequency bands; selecting a first number of frequency bands from the set of candidate frequency bands; deriving an optimal coefficient among combination coefficients for the first number of frequency bands, wherein the combination coefficient is a combination A coefficient matrix between the observation value and a measurement value matrix composed of the pseudorange measurement value and the carrier phase measurement value for each frequency band; and based on the determined optimal coefficient of the combination coefficient, the positioning result information is obtained.

Description

technical field [0001] The invention relates to the field of positioning, in particular to a method and device for positioning based on frequency band combinations of a positioning system, and a method for real-time positioning of goods executed by a server. Background technique [0002] With the rise of the e-commerce industry and the accelerated pace of life of customers, online shopping has also spread to wider areas such as rural areas, so customers have higher and higher requirements for the accuracy and real-time positioning of logistics goods. If the goods can be positioned accurately in real time, the real-time performance of goods positioning can be greatly improved, the logistics cost can be reduced, and the needs of customers can be satisfied to the greatest extent. [0003] At present, cargo positioning is mainly GPS positioning. However, in some high mountains, densely built or remote areas, the GPS signal frequency band cannot be fully provided. In addition, ...
