The ASHTECH xn GPS receiver, designed to make fuH use of the Navstar Global Positioning System, provides state-of-theart precision surveying and navigation. Model xn, the most sophisticated GPS receiver available today , is the first to offer true ALL-IN-VIEW automatic tracking. With twelve independent channels, it tracks all the satellites in view automatically , erasing the need for manual, programmed or pre-programmed selection of common satellites between survey sites.

Antenna Platform A geodetic microstrip antenna, figures 3 and 4, is seated on a precision machined platform protected by a weatherproof cover. A low- noise preamplifier housed at the base of the antenna provides sufficient gain for a cable up to 30 meters long. (Cable specifications are in Appendix C.)

Tbe antenna platform can be mounted on a variety of tripods and range poles, using either a SlIdl thread~ connector or tribrach connector. The special Ashtech GPS blpod range pole is useful for all kinematic survey use.
Eight dog-Iegged holes, labeled A to H, in the antenna's pound plane, allow antenna height measurement. Use the special sectioned measuring rod (the HI rod for height of instrument) and measure through one of these openings. When the HI rods are used this way, the distance from the center of

The ASHTECH xn GPS receiver, designed to make fuH use of the Navstar Global Positioning System, provides state-of-theart precision surveying and navigation. Model xn, the most sophisticated GPS receiver available today , is the first to offer true ALL-IN-VIEW automatic tracking. With twelve independent channels, it tracks all the satellites in view automatically , erasing the need for manual, programmed or pre-programmed selection of common satellites between survey sites.

Antenna Platform A geodetic microstrip antenna, figures 3 and 4, is seated on a precision machined platform protected by a weatherproof cover. A low- noise preamplifier housed at the base of the antenna provides sufficient gain for a cable up to 30 meters long. (Cable specifications are in Appendix C.)

Tbe antenna platform can be mounted on a variety of tripods and range poles, using either a SlIdl thread~ connector or tribrach connector. The special Ashtech GPS blpod range pole is useful for all kinematic survey use.
Eight dog-Iegged holes, labeled A to H, in the antenna's pound plane, allow antenna height measurement. Use the special sectioned measuring rod (the HI rod for height of instrument) and measure through one of these openings. When the HI rods are used this way, the distance from the center of
