China successfully launches two remote sensing satellites

The satellites have entered the planned orbits, and will be used for electromagnetic environment surveys and other related technology tests, the report added.

This was the first flight of the upper stage named Yuanzheng-1S, or Expedition-1S. It cooperated well with the Long March-2C rocket and much improved the carrying capacity of the rocket, according to the China Academy of Launch Vehicle Technology.

The launch was the 286th mission of the Long March rocket series.

Remote sensing generally refers to the use of sensor technologies to detect objects. The remote sensing satellites collect data by detecting the energy reflected from the Earth.
