This is a Geodetic Control Test Field located at L Radial Surveying( Cartwheel): Madison County, Central Ohio. lial Surveys: one receiver at a fixed 2 Madison County High Altitude Test Range site, and measuring lines from this fixed

1.1 Terminology Definitions 3. Point Positioning ys. Relative positioning The coordinates of a single point are determined when 1. Code Range vs, Carrier Phase Code measurements(meter level) Carrier phase measurements(millimeter range). Single point positioning

1.1 Point Positioning with Code ranges Epoch at t Additional Satellites(Simultaneously): L Code Range Observation Equatio

1. 1 Error Categories 1. Errors related to GPs Satellites 2. Errors related to GPS signal propagation

1.1 Physical Fundamentals This attenuation is usually expressed in decibels (dB). By definition, an attenuation of n dB means signal propagation from the that the original field strength is decreased by ite to the user by means of factor of 10-0In electromagnetic waves. Such waves Physical quantities

Perigee and Apogee: The point of closest approach of the satellite with respect to the earth's center of mass is called perigee and the most distant position is the apogee. Nodes: The intersection between the equatorial and the nit sphere is termed the nodes, where the ascending node defines the northward
