Abstract:	This paper is focused on describing methods and results to precisely measure P3 aircraft buffeting, i.e. vertical variation of an aircraft tail boom, over periods of 1 to 50 seconds, to an accuracy of a few centimeters. GPS receivers with carrier phase data output rates of at least 10 Hz with an L1 capability will first be tested using a DGPS signal simulator to determine the receiver carrier phase tracking loop stability under aircraft dynamics and static conditions. Atmospheric effects will be simulated, along with other errors, to evaluate the accuracy obtainable as a function of the observation mode (single point versus differential) under static and kinematic simulated conditions. Field test data collected in a moving automobile will also be used to assess carrier phase methods as a function of reference receiver distance. Both fixed and floated filtering approaches will be investigated. Field test data over a long baseline will be assessed in both single point and differential mode over a period of several hours.
