In the Shanghai Science and Technology award ceremony, the core technology of CHC dual frequency surveying GPS receiver won Shanghai's science and technology progress award.

The committee gives high appraisal of the core technology of CHC dual frequency surveying GPS receiver, they pointed out that the core technology has the real own intellectual property rights and has reached the international advanced level. This technology has largely promoted the domestic GPS industry development, and it will make the GPS application be adopted in large-scale.

The core technology of CHC dual frequency surveying GPS receiver is the first generation key surveying GPS technology of China which was fully developed by us. The leader of this field, the president of CHC Dr. Yongquan Wang developed the China?s first static surveying GPS receiver and the first dual frequency RTK receiver.

This core technology has the quicker positioning, using in large area, working long distance, stable signal and high accuracy and so on advantages. It is complete capable with the same type national or international brand GPS receiver, and has surpassed the imported products in many technical parameters. It is the highest level of national even the international surveying GPS technology.(By Andy Yin)
