At the end of October this year, the first permanent GPS station was installed in Loreto. Permanent, geodetic-grade GPS is a quantum leap beyond the GPS device you take hiking or operating inside your smartphone. “Geodesy” refers to high-precision measurements of the surface of the earth, changes in the land surface, and precise positioning or navigation. Geodetic GPS equipment can measure locations hundreds of times more accurately than hand-held GPS equipment, providing the levels of precision needed for most scientific and many commercial applications. Permanent GPS receivers operate at a fixed location, taking measurements constantly, and providing a base station for any other GPS surveying or measurement in the region.
