Tiangong-2: Mission Support
Jump to: Mission Support Status, Mission Support Request
ILRS Mission Support Status:
SLR will be utilized to validate the accuracy of the TG-2 precise orbits that are computed by GPS observations.
ILRS support of Tiangong-2 will be divided into two phases depending upon the configuration of the satellite. To support the first phase of ILRS tracking of Tiangong-2 (1 August - 31 October), the ultraviolet edge detector is turned off (laser ranging can affect the data from this instrument). Since Tiangong-2 has two attitude modes, the Earth-pointing and yaw-steering, there may also be station visibility issues. The Earth-pointing configuration will last about 1 month. The yaw-steering configuration will last about 0.5 month; the retroreflector array is not accessible at that time. The mission contacts will inform the stations in advance of these periods of attitude mode.
In order to support the second phase of ILRS support, when the ultraviolet edge detector is operating, the ILRS will need to identify possible options for restricted tracking.
