in space under the size constraints of available delivery vehicles. A large space antenna should make it possible to improve the telecommunication bandwidth and reduce the size of ground terminals. reliable and precise deployment. Since the antenna is a highly complex structure, monitoring the deployment process and the detection of anomalies are also important. The deployed antenna should be collimated to achieve its optimal performance. such as tension and acceleration sensors. With a visual analysis, we can acquire information at many locations without complex wiring, which can increase the complexity of the system. Therefore, visual analysis should be used in conjunction with other methods for monitoring large deployable antennas. combination of cross-correlations between images and approximation at sub-pixel precision enables us to detect shifts in images with a precision of up to 0.01 pixels. This method is effective for monitoring and collimation of a deployable antenna. broadcast technologies which was developed by the National Space Development Agency of Japan (NASDA) under the cooperation with Communications Research Lab. and NTT Network Innovation Lab.. One of the most important missions of ETS-VIII is to construct a large deployable antenna for S-band telecommunication. In December 2001, the LDREX mission, which was a preliminary experiment for the large deployable antenna of ETS-VIII , was performed as an Ariane-5 auxiliary payload (ASAP). A 6m scale model of the ETS-VIII deployable antenna was launched and deployed in geo-transfer orbit (GTO). During this experiment, anomalies occurred in the deployable antenna, and deployment was aborted. analysis method. Using this analysis, we detected vibrating features of the deployable antenna , which were useful for explaining the anomalies deployable antenna.
