The C-band (5.6 GHz) radar transponder onboard the satellite carried out the following experiments : (1) Performance test of C-band tracking radar. Orbit estimation was tried on the basis of the tracking data from only a single station.The serial estimation orbit deta was utilized for a laser ranging experiment made at the Dodaira Observatory, Univ. of Tokyo. (2) Investigation of the influence of the atmospheric refraction on the estimation of satellite orbit. (3) Experiment of multitracking system with the C-band radars at Tanegasima and Ogasawara of NASDA (National Space Development Agecy of Japan). As for the case of the expriment (1), tracking deta from two revolutions give a precise estimation using comparatively small size of computer programming in a short execute time., 資料番号: SA0166035000}, pages = {1--33}, title = {レーダによる試験衛星「たんせい4号」の追跡及び軌道推定}, volume = {2}, year = {1982} }
