Abstract: The present invention provides a method for the attitude control of satellites in elliptic orbits or satellites initially placed in circular orbits perturbed to elliptic orbits due to environmental disturbances. The method relies on the application of solar radiation pressure to provide the desired torque for the satellite attitude control. The satellite is equipped with two-oppositely placed light-weight solar panels extending away from the satellite along a predetermined direction (satellite body fixed Y-axis). By rotating one of these solar panels or both of them through desired angles about their axis using the respective driver motors as per the simple open-loop control law, the torque about the satellite axis is developed to achieve the desired attitude performance. The open-loop control law is derived using an analytical approach to neutralize the excitation caused by eccentricity and it is implemented via analog logic based on the information of sun angle and satellite position provided by the sensors. The present invention significantly improves the performance of the satellite by a factor of more than 20 times approximately in general and it only requires the rotation of the solar panels by fraction of a degree for particular system parameters. Thus, the semi-passive nature of the present invention makes it attractive for future space applications.
Abstract translation: 本发明提供一种用于由于环境扰动，椭圆轨道或卫星中的卫星的姿态控制方法，该方法最初被置于扰动到椭圆轨道的圆轨道中。 该方法依赖于太阳辐射压力的应用，为卫星姿态控制提供所需的扭矩。 卫星配备了两个相对放置的轻量级太阳能电池板，沿着预定方向（卫星固定的Y轴）远离卫星延伸。 通过根据简单的开环控制规律，使用相应的驱动器电动机将这些太阳能电池板中的一个或它们两个绕其轴线旋转所需的角度，开发关于卫星轴线的扭矩以实现期望的姿态性能。 开环控制规律是通过分析方法得出的，用于中和由偏心引起的激励，并通过模拟逻辑基于由传感器提供的太阳角和卫星位置的信息来实现。 本发明通常将卫星的性能显着地提高了大约20倍，并且仅需要太阳能电池板的转动为特定系统参数的一定程度的旋转。 因此，本发明的半被动特性使其对未来的空间应用具有吸引力。

Abstract: An optoelectronic assembly includes a circuit board having a set of signal traces, where one or more of the signal traces has a junction point that integrates a pad of a circuit element. Exemplary circuit elements include a resistor, capacitor, and an inductor. The junction point has a first width and a first thickness, and the one or more signal traces have a second width and a second thickness. The dimensions of the junction point and the dimensions of the one or more signal traces are configured such that the first width and the second width are substantially similar, and that the first thickness and the second thickness are substantially similar. In one embodiment, the first width is no greater than 125% of the second width.

Abstract: A transceiver module is provided that includes an optical subassembly having an extension with traces corresponding to traces defined on an associated transceiver substrate. A connector element including a flexible, non-electrically conductive substrate within which is disposed an array of conductors is placed between overlapping portions of the extension and the transceiver substrate so that upper ends of some of the conductors contact the traces of the extension, while lower ends of those same conductors contact the corresponding traces of the transceiver substrate. In this way, the connector element provides electrical communication between the optical subassembly and transceiver substrate, while also accommodating misalignment that may be present, or develop, in the transceiver module components.
