2010年4月8日,世界上最大的固定卫星服务供应商—国际通信卫星有限公司(INTELSAT)与其银河-15(Galaxy-15)卫星失去了联系,该卫星开始从其地球静止轨道(GEO)位置向东漂移,而它的转发器仍在工作。因此该卫星被媒体称作“僵尸卫星”(Zombiesat)。这意味着银河-15卫星将对地球静止轨道区域内其他卫星的运行造成严重影响。
On April 8, 2010, INTELSAT, the world’s largest provider of fixed satellite services, lost contact with its Galaxy-15 satellite, which began moving from its geostationary orbit (GEO) The position drifts eastward while its transponder is still working. So the satellite is called “Zombiesat” by the media. This means that Galaxy-15 will have a serious impact on the operation of other satellites in the geostationary orbit.
