The development of low-cost GNSS receivers broadens their applications, such as deformation monitoring, which have been performed routinely by survey-grade receivers. To evaluate the performance receivers, we assessed precision multi-GNSS in monitoring dynamic motion and developed methods using a closely-spaced dual receivers' system to enhance performance. In this study, both receiver/antennas were mounted on circular rotating device executing controlled periodic rotation. It was shown that could be enhanced level 2–4 mm, observations limiting noise based error modelling filtering closely–spaced Finally, from experiments real bridge application, it proved accurately define modal frequencies ∼0.362 Hz ∼1.680 Hz, respectively.
