xyzspace

xyzspace is a conceptual data framework and coordinate system used in space research and engineering to model the position and motion of objects in three-dimensional space relative to a chosen reference frame. It provides a standardized representation for state vectors, object metadata, and event information, enabling consistent simulation, analysis, and interchange between tools and organizations.

The concept originated in the early 2020s as part of efforts to harmonize space situational awareness and mission-design toolchains. An open specification and reference implementations were published by a consortium of universities and industry partners in 2024, with subsequent updates to address evolving needs such as debris tracking, formation flying, and deep-space missions.

Its core structure includes: spatial coordinates (x, y, z); velocity components (vx, vy, vz); a time stamp; an identifier and object type (satellite, debris, spacecraft, vehicle); attitude information; and health or status indicators. It supports multiple reference frames, including inertial and rotating frames, and commonly used local frames such as LVLH. The data model is designed to serialize to interoperable formats such as JSON, XML, and compact binary forms, and to support trajectory propagation and basic collision-risk assessment.

Applications include mission design and trajectory optimization, space traffic management, simulation training, and academic research. xyzspace aims to reduce integration overhead by providing a shared vocabulary and tool interfaces across simulators, sensors, and ground systems. Adoption has grown in universities, aerospace companies, and some space agencies, though governance and versioning remain important to avoid fragmentation.
