内容記述 | The balloon flight performance of the Mark I single-axis platform and telescope is presented. Three performance indicators are examined: inclinometer output, gyro output, and infrared detector signal. The gondola itself experiences periodic angular disturbances with maximum amplitudes in the 0.1-2.0 deg range, with peaks occurring at periods of about 1, 2, 7, 20, and 250 s. The 2- and 20-s oscillations are identified with simple and compound pendulum motions, while the 250-s oscillations are speculated to be caused by atmospheric waves. The system meets the basic goal of providing a stable pointing direction within an uncertainty which is much less than the 0.3 deg telescope beam diameter. |
