| Popis: | The Planet-A and MS-T5 missions are the first deep-space missions not only for ISAS, but also for Japan. Escaping the gravity field of the Earth, the spacecrafts travel around the Sun for 8 months for the former and 14 months for the latter until the encounter with Halley's comet. During these periods, ISAS is planning to perform its own tracking using the 64 mφ antenna which is under construction at Usuda, Nagano prefecture. For this purpose, precise trajectory of the spacecrafts must be computed, taking into account all the accelerations such as gravity of Sun, Moon, 9 planets, solar pressure, general relativity effect, etc. A large scale software called TRIP has been developed based on such mathematical model, taking advantage of the advanced numerical integration techniques and the basic concept as well as the software structre are described in this report. 資料番号: SA0166004000 |
