Scope
GB/T 42042-2022 is the English-translated version of 空间站坐标系.
GB/T 42042-2022 fixes the coordinate systems used for the Chinese space station.
It covers the numbering of the station and its modules, the definition and conversion of the quadrant lines, and the individual coordinate systems: those of the Tianhe core module, of the Wentian and Mengtian experiment modules, of the assembled complex, the manipulator and the space applications, with a normative appendix on the transformations between them.
Clause 4 defines the core module quadrant lines as four module generatrices 90° apart, numbered I to IV clockwise when seen from the rear of the resource section along the longitudinal axis in the direction of flight.
Clause 1 applies the document to engineering development, launch, in-orbit operation, assembly and flight control of the station. It quotes GB/T 32296-2015. Issued on 12 October 2022, it has applied since the same date.

3 Terms and Definitions
This document does not have terms and definitions that need to be defined.
4 Quadrants and coding
4.1 Spacecraft quadrants
4.1.1 Sky and Core Module Quadrant Lines
The sky and core module quadrants are the baselines used to characterize the sky and core module. On the aircraft, the four cabin mothers with an opening angle of 90° The line is the quadrant line of the sky and the core cabin. As shown in Figure 1, the sky and the core cabin fly from the rear end of the resource cabin along the longitudinal axis (the symmetrical longitudinal axis of the sky and the core cabin).
Viewed in the row direction, the quadrants in the clockwise direction change to I, II, III, and IV. The quadrants are separated by 90°, and the three-axis stable flight to the ground in orbit I image Limit line to ground.
Note: The longitudinal axis of symmetry of the cabin is used to characterize the geometric axis of symmetry of the cabin. coincide. 1)
