本文介绍了澳大利亚空间环境R搜索中心新的高精度目录的轨道要素生成数据要求的分析结果。这项分析工作的目的是利用对碎片和卫星进行光学和激光跟踪所获得的轨道数据，为轨道元素生成制定一套健全的规则。位于澳大利亚斯特罗姆洛山的EOS空间系统有限公司进行的几次跟踪活动中收集的光学和激光跟踪数据经过拟合，可提供最新的轨道要素。针对各种数据可用性场景确定元件精度，包括：（1）仅拟合光学跟踪数据;（2）拟合光学和激光跟踪数据。新的轨道要素的轨道预测与SGP 4 propagation从双线元素数据和精度进行了比较，通过比较高精度星历可用或随后的准确跟踪数据进行评估。最后讨论了该目录的未来整合和改进。这项工作是空间环境管理合作研究中心合作努力的一部分，该中心正在开发保护空间环境的新技术和战略（www.serc.org.au）。
In this paper results are presented from an analysi s assessing the data requirements for orbit element generation for a new high-accuracy catalogue for the Space Environme nt R search Centre, Australia. The analysis is work ing towards obtaining a robust set of rules for orbit e lement generation using orbital data from optical a nd laser tracking of debris and satellites. Optical and laser tracking data collected from seve ral tracking campaigns carried out by EOS Space Sys tems Pty Ltd, located on Mount Stromlo, Australia, is fitted to provide an updated orbital element. The element accuracy is determined for various data-availability scenarios, ncluding: (1) fitting optical tracking data only; (2) fitting optical and laser tracking data. The orbit predictions from the new orbital element are compared with SGP4 pro pagation from two-line element data and accuracy is assessed by comparing with high accuracy ephemerides where available or subsequent accurate tracking data. Future integr ation and enhancements to the catalogue are also di scussed. This work forms part of the collaborative effort of the Space Environment Management Cooperative Resea rch Centre which is developing new technologies and str ategies to preserve the space environment ( www.serc.org.au ).
