User equivalent ranging error (UERE) of navigation satellites which is based on broadcast message is affected by a number of factors. Multipath effect is one of the major contributor to the error of pseudo range. Experiments and tests are to determine that how error of pseudo range is connected to the shape of a satellite, and to verify how to lessen multipath effect by a re-arranging the outer structure of a satellite, such as solar arrays or antennas. A series of equipment and infrastructure are built according to the technical conditions of the experiment.
