Military meteorological sat carrying an Interferometric Imaging Radar Altimeter (InIRA). This spaceborne wide-swath ocean radar altimeter was tested on board Tiangong-2 lab and can perform imaging and acquire elevation information simultaneously. The in-orbit observation results of Tiangong-2 InIRA demonstrate that it is capable of measuring the dynamic sea surface height with wide swath, sea waves of different scales and sea winds, which greatly improve the observation and measurement efficiency compared with traditional nadir-looking radar altimeters.Another launch today. A Long March 6 rocket has successfully inserted the Yunhai-3 (云海三号) satellite into the pre-determined orbit. Sorry, but no high quality images of the launch are available at this time, but here are some pre-launch images to compensate.
