Abstract: Provided in the present disclosure are a positioning method and apparatus based on a binary periodic sequence. The method includes: selecting one polynomial from each equivalence class of a quadratic polynomial set S to determine a set T; constructing a binary periodic sequence cluster according to the set T; generating a positioning signal according to the binary periodic sequence cluster; and performing positioning processing according to the positioning signal.

Abstract: Disclosed are a cooperative positioning method and apparatus, a device, and a non-transitory computer-readable storage medium. The method may include: determining an initial positioning estimated value of each of a plurality of objects to be measured by a simulated annealing algorithm and a first preset positioning algorithm; screening at least two distance measurement values based on a preset error threshold to obtain a target distance measurement value, where the at least two distance measurement values are measurement values obtained by measuring a distance between each object to be measured and each of a plurality of target base stations for at least two times; and determining a position of each object to be measured according to a multi-target-source Taylor series algorithm, each target distance measurement value and each initial positioning estimated value.
