Velocity and Acceleration from Unaided Carrier Phase

James L. Farrell

Abstract:	Sequential changes in carrier phase are used to obtain three-dimensional velocity and acceleration in a block processing algorithm, unaided (i.e., without usage of the IMU data). As in previously documented (IMU-aided) related exercises, position is derived by combining feedforward velocity history with pseudorange corrections. Flight results, shown for different cases with acceleration modeled as constant over various intervals (3-s and 8-s), produce RMS residuals at decimeter/s levels with 1 - Hz updates. Results are interpreted in light of practical applications and limitations in comparison vs. alternate configurations.
