Abstract
A portable geodetic surveying station is disclosed which utilizes a GPS antenna attached to the top portion of a surveyor's stake, or other type monopod. By positioning the bottom portion of the monopod directly upon a desired ground location, and adjusting the angular position of the monopod so that it is precisely vertical, the GPS antenna may be quickly and accurately positioned level and directly above the desired ground location. Additionally, because the monopod has a known, fixed length, the height of the GPS antenna above the desired ground location will always be a constant, and will not vary from one survey point to the next. The GPS antenna and monopod are designed to be used in conjunction with a newly designed geodetic surveying tripod which can be quickly and conveniently set up to support the monopod in its vertical position directly above the desired ground location. The tripod of the present invention includes a tripod head which comprises a base platform, a first housing slidably mounted on the platform to permit the first housing to move along a first directional path, and a second housing slidably mounted within the first housing to permit the second housing to …
