自由运动状态轨道模拟是怎样的
通过太空卫星的 OAV 空气轴承实现
Exceptional feats are forged from the very fundamental roots of an objective. Continual improvement of those roots will lay way to tremendous accomplishments and advancements. At OAV Air Bearings, we emphasize that a strong foundation is the essence of growth. The frictionless and precision capabilities of OAV Air Bearings allows for the growth of incredibly unique and monumental endeavors. Celestial activities are one such example.
Satellite communication and earth observation impacts life in a multitude of ways. From communications to research and data, satellites are a critical component to what we know and utilize today. Through the use of cubesats, Open Cosmos specializes in critical satellite communication and observation. Cubesats are miniature satellites, based around a size configuration between 10 cm and 30 cm, in the form of a square that are launched into orbit by deployers. These nanosatellites are responsible for collecting a wide range of data, from global disasters, to scientific research studies, to energy and resources, to communication and logistics.
The assembly and test team at Open Cosmos produces and tests these devices to fulfill their objectives. Through the use of the novel OAV Roller Air Bearing, the team is able to successfully simulate satellites in a free motion state orbit and test the attitude control system. The air bearing is placed on a stand, and the spacecraft onto the air bearing. By providing frictionless motion around one axis, the air bearing allows the team to test the attitude control system one axis after another. From the grounds of earth, Open Cosmos is able to recreate a virtually frictionless and microgravity environment for celestial based research with the OAV Air Bearing.
非凡的成就是从一个目标的最基本的根源中锻造出来的。持续改进这些根源将为巨大的成就和进步铺平道路。在 OAV 空气轴承，我们强调坚实的基础是增长的本质。 OAV 空气轴承的无摩擦和精密性能允许令人难以置信的独特和巨大的努力的增长。天体活动就是这样的例子之一。
卫星通信和地球观测以多种方式影响着生活。从通信到研究和数据，卫星是我们今天所了解和使用的重要组成部分。通过使用立方体卫星，Open Cosmos 专注于关键卫星通信和观测。立方体卫星是微型卫星，尺寸配置在 10 厘米到 30 厘米之间，呈正方形，由部署者发射进入轨道。这些纳米卫星负责收集范围广泛的数据，从全球灾难，到科学研究，到能源和资源，再到通信和物流。
Open Cosmos 的组装和测试团队生产和测试这些设备以实现其目标。通过使用新颖的OAV Roller Air Bearing，该团队成功模拟卫星处于自由运动状态的轨道，并测试姿态控制系统。空气轴承放在支架上，航天器放在空气轴承上。通过围绕一个轴提供无摩擦运动，空气轴承允许团队一个接一个地测试姿态控制系统。从地球地面，Open Cosmos 能够使用 OAV 空气轴承为基于天体的研究重建一个几乎无摩擦和微重力的环境。
在使用 OAV 空气轴承产品之前，该团队通过模拟计算和分析收集了这些数据。这一时期的主要挑战是模拟和计算的真实准确度的不确定性。通过使用空气轴承，该团队现在能够对此类场景进行物理模拟，以确认他们的计算是否完整准确。
