Orbit Determination from Observation topics include: Orbit determination observations like ground tracks and time systems, space surveillance, sensors types and locations. Orbit determination is the process of estimating the orbits of objects like planets, moons, and spacecraft. The goal is to understand the amount of error that can be expected in a calculation. The process of orbit determination usually involves: Sensor subsystem: Contains sensing instruments such as star sensors, earth sensors, and magnetometers Model subsystem: Part of the orbit determination system Filter subsystem:...

The process of orbit determination usually involves: Sensor subsystem: Contains sensing instruments such as star sensors, earth sensors, and magnetometers Model subsystem: Part of the orbit determination system Filter subsystem: Part of the orbit determination system The process involves comparing the difference between measurement data and estimated data in a statistical sense. Some examples of angles-only techniques include: The method of Laplace The method of Gauss The double r-iteration method The method of Laplace uses a series of successive differentiations of the data to provide accurate orbital data for the middle observation. Naked-eye observations are insufficient to determine precise orbits, so telescopes or radar equipment are used. Related Test: Spaceflight Mechanics Practice Test: Basic Orbital Maneuvers Show less
