WEST LAFAYETTE, Ind. — Engineers at Purdue University and NASA have developed a new technique for monitoring the environment by using routine signals that already are being beamed to Earth by global positioning systems. Conventional techniques for gathering information about global climate change and other environmental data require systems that have their own transmitters and receivers on satellites or aircraft. The equipment, though, is relatively heavy and consumes large amounts of power.
The above story is based on materials provided by Purdue University. Note: Materials may be edited for content and length.
