This invention provides a time slot planning method and system for a navigation constellation time division multiplexing network, comprising an initialization module, a preprocessing module, a fully autonomous navigation time slot planning module, a non-fully autonomous navigation time slot planning module, and an output module. It sets a navigation constellation time slot table composed of MEO dynamic and static link time slot tables, IGSO dynamic link time slot tables, and GEO dynamic link time slot tables, and determines the total number of time slots to be selected for each time slot table. After initializing the time slot table, according to the prescribed principles of uniqueness within the same column, mutual reference within the same column, rolling filling, uniqueness in the same row, and priority for smaller PDOP values, it generates time slot tables adapted for measurement-centric and communication-secondary functions for two typical scenarios: fully autonomous navigation supported only by inter-satellite links and non-fully autonomous navigation supported by inter-satellite and satellite-to-ground links. This invention generates time slot tables that meet the requirements of measurement-centric and communication-secondary functions under different navigation scenarios through a unified method, possessing good completeness, system compatibility, and task flexibility.

The invention discloses a method for improving rolling uniformity of a multi-core superconducting strip. The method specifically comprises the steps that a plurality of core materials are subjected to tubing treatment, then the composite pipe subjected to tubing treatment is subjected to drawing, rolling and heat treatment, the core materials are regular hexagon core materials, and the core materials are single-core core materials or core materials obtained through tubing treatment. According to the invention, the regular hexagon single core (or multi-core) is used for secondary (or multiple) tubing, so that the deformation of the multi-core round wire in the drawing process is changed, the section of the superconducting core is changed from an original irregular shape to an approximately circular shape, and the stress condition of the single superconducting core in the rolling process is closer to that of a single-core strip; and finally, the superconducting core with uniform density and texture degree is obtained. In addition, geometric stability can be enhanced, and uncertain deformation is avoided.
