More than 1,600 teachers and students from Harbin Engineering University in Heilongjiang province recently finished three massive snow sketches on the snow-covered campus, including one of China's third aircraft carrier, the CNS Fujian, and the mascots of the 9th Asian Winter Games, Binbin and Nini.

Students mapped out the sketches using high-precision positioning from the Beidou Navigation Satellite System.

Viewed from above, Binbin and Nini soar into the air on a snowboard, as if saying hello to welcome visitors from around the world.
