Abstract：Shape accuracy is one of the key indicators for evaluating the performance of large spaceborne antennas. Based on three-dimensional coordinate measurement, the measurement and calculation method of large-scale expandable mesh antenna shape accuracy was introduced. By using the theodolite measuring system, photogrammetry system and laser scanner, a comparative experiment was designed to measure the shape accuracy of a large expandable mesh antenna model for a certain model, and the advantages and disadvantages of the three measurement methods were compared. The conclusions have guiding significance for the evaluation of the shape accuracy of the same type of spaceborne large expandable mesh antenna products.

Key words： metrology shape accuracy expandable mesh antenna measurement
