| 2. | Hopefully in 5 to 10 years time we can celebrate the launch of the first chinese astronomical satellite
我们希望能在五至十年间庆祝中国发射首枚天文卫星吧。 |
| 3. | With an array of new astronomical satellites soon to be launched in the next few years , we sure would be able to learn more about these mysterious objects
未来数年，一系列新的天文卫星将会投入服务，届时可对这些神秘的物体-黑洞有著更多的认识。 |
| 4. | The infrared astronomical satellite was a joint mission between us , uk and the netherlands . it was the first telescope to have performed an all sky survey in the infrared
红外线天文卫星由美国英国及荷兰联合发射，它是首个以红外线进行全天探测的望远镜。 |
| 5. | In order to test the performance of the attitude determination and control methods presented in this thesis , the whole simulation loop of the small astronomical satellite ' s adcs was constructed
3 )为了充分验证本文提出的姿态确定和控制方法的效果，本文的最后建立了svom卫星姿控系统大回路模型，并编写了相应程序，进行了数学仿真。 |
| 6. | This thesis took a small astronomical satellite as an example , deeply studied the attitude determination and control method for small astronomical satellites from both the theoretical and the engineering aspects
本文以正在研制的一颗小型天文卫星? ? svom卫星的姿态确定与控制方案设计为背景，从理论和工程两方面较为全面地研究了小型天文卫星的高精度姿态确定与控制方法。 |
| 7. | The infrared astronomical satellite launched in 1982 , followed by the infrared space observatory launched in 1995 , have discovered stardust made up of minerals ranging from common rocks of silicates and carbonates , to rare stones similar to rubies and sapphires
1982年发射的红外线天文卫星和1995年发射的红外线空间天文台，发现了星尘不单蕴藏著硅酸盐和碳酸盐这类常见的矿物质，甚至有类似红宝石和蓝宝石的罕有矿石。 |
| 8. | The small astronomical satellite has demands on both pointing accuracy and attitude maneuverability , so this thesis modeled the attitude control subsystem based on reaction wheels . under the fine precision pointing mode , a pd control law and a variable structure ( vs ) control law were studied respectively , and the simulation validated that vs control is more effective under fine precision pointing mode . furthermore , the vs controller for rapid large - angle maneuver was also designed
2 ) svom卫星同时对指向精度和姿态机动性有着很高的要求，因此本文建立了基于反作用飞轮的svom卫星姿态控制系统模型，在高精度惯性定向三轴稳定模式下分别设计了pd控制律和变结构控制律，通过仿真验证了变结构控制对于svom卫星的有效性，并基于变结构控制研究了svom卫星快速大角度机动的方法。 |
