| Resumo | The purpose of this paper is to estimate in real time, the position coordinates of a fixed GPS receiver (user) based on another receiver located on a landmark with known position (base), through the differential GPS technique (DGPS). The user receiver is purposely placed at a known distance, which makes possible the verification of accuracy of the method. The differential GPS technique consists of two well defined steps: 1) generating corrections in the reference "base"; 2) applying the corrections in the user receiver. The reference base has its position coordinates precisely known, so that it can calculate either the correction on position coordinates with respect to the landmark, or the correction on the raw pseudorange measurements for each GPS satellite. Due to the base and user proximity, the differential GPS principle assumes that environmental effects (troposphere and ionosphere mainly) are the same, for close baselines. Thus, complex modeling effects are prevented and the technique gives origin to a high accuracy relative positioning. The data were collected by dual frequency GPS receivers, geodetic quality, Ashtec Z12, in a campaign of about one hour with 1 Hz of sampling rate. They were processed using both techniques, namely DGPS on position, using a least squares method, and DGPS on measurements, through a Kalman filter, and the results are compared with the known distance between receivers. The results obtained with DGPS techniques show an improvement with respect to stand-alone GPS, with an accuracy better than 3 m for the test cases. They allow to establish the basis for the development of a real time estimation method of the receiver position and to verify the accuracy achieved with the DGPS techniques. This is an important step in developing a differential GPS system to be further implemented in dynamically mobile platforms, like aircraft, ships, and cars.. |
