BEIJING (Reuters) - Chinese scientists will use satellite technology to peep on the sexual antics of China's highly endangered giant pandas, Xinhua news agency said.

The $660,000 (372,165 pounds) joint project between two Chinese and U.S.-based zoological institutes would use global positioning (GPS) to keep an eye on giant pandas and their mating behaviour deep in the wilds of a nature reserve in central Shaanxi province.

Pandas in the wild are rebounding from the brink of extinction, but they are not yet out of the woods, in large part because of great difficulties in producing cubs.
