Section 0820-03-.11 - GLOBAL POSITION SYSTEMS SURVEYS(1) Global Positioning Systems (GPS) are defined as the navigation and positioning systems that comprise the Global Navigation Satellite System (GNSS), which includes NAVSTAR, GLONASS, GALILEO, COMPASS, and any other satellite-based navigation and positioning systems.(2) The professional Land Surveyor in responsible charge of the GPS survey shall note on all prepared documents the following information. When a map or document consists of more than one (1) sheet, only one (1) sheet must contain the notes. (a) Type of GPS field procedure, such as Static, Kinematic, Psuedo-Kinematic, Real-time Kinematic, Real-time Kinematic networks, and Online Position User Service;(b) Relative positional accuracy or other mathematical expression as chosen by the Land Surveyor;(d) What datum and epoch coordinates or geographic positions are based on;(e) Designation of fixed-control stations and their positional data;(f) Geoid model used; and(g) Combined grid factor(s).(3) GPS surveys performed to provide control networks shall be performed in such a manner to obtain a ninety-five percent (95%) confidence level of the positional accuracy of each point relative to the published positions of the control points used.(4) Fixed station(s) used for the project shall appear on the map, plat, or report. The minimum data shown for each fixed station shall be station name, horizontal position (northing and easting) or latitude, longitude, elevation (ellipsoid or orthometric), and datum and epoch.Tenn.
