Influência do erro de estimação do comprimento das baselines na determinação da atitude GNSS

Abstract

The carrier phase measurements are inevitably necessary in problems involving high accuracy GNSS (Global Navigation Satellite System) positioning. The challenge in using this measurement is to estimate the phase ambiguity. For real time applications, the ambiguities should be solved with the least possible amount of data, but this can affect the accuracy of baselines and therefore attitude. The distance between receivers affect attitude precision. This work shows the influence of the baseline length attitude determination on-the-fly.
