J2摄动作用下近地轨道卫星编队构形长期演化机理分析

Analysis of LEO Satellite Formation Secular Evolvement with J_2 Effect

首先给出考虑J2摄动项时近地轨道卫星的轨道模型、星下点计算方法和覆盖判断准则，在此基础上给出一种近地回归轨道的迭代设计方法。

The orbit models , the calculation methods of sub satellite and the coverage judgement which take into account the J 2 perturbations are given first , and then an iterating methods of designing satellite orbit with repeat ground trace is proposed .

近地轨道卫星导航系统的缺点是用户需要等待卫星通过其上空，甚至测量也需要花上几分钟的时间。

The drawbacks of low-Earth orbit navigation satellites are that the user may have to wait for a satellite pass and even then the measurement takes several minutes .

根据新闻媒体的报道，中国可能能够用低能量激光，使近地轨道卫星的传感器“致盲”，虽然还不清楚这种说法是否涉及实际的设备。

According to press accounts , China can use probable low-energy lasers to " blind " the sensors on low-Earth-orbiting satellites , although whether this claim extends to actual facilities is unclear .

航天测控。中国已建成完整的航天测控网，包括陆地测控站和海上测控船，圆满完成了从近地轨道卫星到地球静止轨道卫星、从卫星到试验飞船的航天测控任务。

TT monitoring : tt China has established an integrated TT network comprising TT ground stations and ships , which has successfully accomplished TT missions for near-earth orbit and geo-stationary orbit satellites , and experimental spacecraft .

不过，它也承认，广泛地部署近地轨道立方体卫星并非没有风险。

Yet it also acknowledges that widespread deployment of LEO CubeSats isn 't risk-flee .

这适用于所有，近地轨道的卫星。

And that holds for all near-Earth-orbit satellites .

MDIF公司这个名叫外联网的项目，计划到2015年向近地轨道发射数百颗卫星。
