北京，1月28日 -- 春节前夕，西安卫星测控中心对我国在轨运行的52颗北斗导航卫星进行了逐个“体检”，结果表明，所有卫星关键技术指标均满足正常提供各类服务的要求。
BEIJING, Jan.28--Xi'an Satellite Control Center(XSCC) has inspected 52 Chinese BeiDou navigation satellites (BDS) in orbit one by one before the Chinese New Year and Spring Festival. The key technical indicators of all satellites met the requirements for the normal provision of various services.
“这次评估工作，由系统总体完成审核后，在不影响正常提供导航服务的原则下，由测控系统组织卫星研制单位和用户部门共同实施。”
中心某室主任陈宁说。 "After the overall review of the system, the satellite R&D department, together with the client department, organized the inspection and evaluation work without affecting the normal provision of navigation services," said Chen Ning, an official from XSCC.
工作人员在完成检测研判的同时，还为每颗卫星制定了个性化维护保养计划，确保卫星持续保持良好工作状态。
While completing the inspection and evaluation, the staff also formulated a customized maintenance plan for each satellite to ensure their good working conditions in future.
据了解，北斗全球卫星导航系统正式开通以来，西安卫星测控中心作为北斗测控和星间链路两大核心系统的主责单位，圆满完成了对全系统日常运维、例行控制、异常处置等工作。
It is reported that since the official opening of the BeiDou global satellite navigation system, XSCC has successfully completed the daily operation and maintenance, routine control and abnormal handling works all the time, as the main unit responsible for the two core system, the BeiDou measurement and control system as well as the inter-satellite link system.
“除了每半年对全部北斗导航卫星开展健康评估工作外，我们每季度还要对在轨运行时间超设计指标的卫星进行健康评估，全力保证每一颗卫星健康在轨运行。”工程师吕朋亮介绍。
"In addition to semi-annual assessments on all BDS, we also conduct quarterly assessments on satellites whose in-orbit operation time exceeds the design index to ensure that each satellite operates normally," said the engineer Lve Pengliang.
春节期间，西安卫星测控中心将继续实行24小时全天候值班管理模式，守护好所有“中国星”。
It is learnt that during the upcoming Chinese traditional festival, XSCC will continue to implement the 24-hour on-duty management mode to guard the safe operation of the Beidou satellites.
