China Aerospace national standards applicable to national standards in the field of aerospace and revision Management, covering the management of space, space technology, space applications and services of the three fields, is to guide spacecraft and launch vehicle project management, engineering research System, space launch services, in-orbit satellite applications based activities. Spacecraft in our development process, often involving the concept of different orbits, and to use a lot of the argument. The different research units Orbital parameters and concepts used in symbols are not uniform, for spacecraft development and bring a lot of duplication of work communication barriers. Through rigorous set Justice and norms of classification and spacecraft orbit parameters, help track the use of a unified classification parameters and symbols can be further improved Spacecraft Engineering Cheng Development Coordination and academic exchanges consistency and effectiveness. Spacecraft Orbit classification and symbols commonly used parameters1 ScopeThis standard specifies the classification and spacecraft orbit parameters commonly used symbols spacecraft orbit. This standard applies to artificial earth satellites, spacecraft, space stations, and deep space probes and other spacecraft overall design, track design and related Technical activities. For the center of gravity of the body other than the Earth's deep space probes of other celestial bodies can refer to use.2 spacecraft orbit classification2.1 Classification orbit 2.1.1 Classification orbital eccentricity 2.1.1.1 circular orbit Eccentricity e satisfies the condition e = 0 the track. Orbital eccentricity near circular orbit approximately zero, the project is sometimes referred to a circular orbit. 2.1.1.2 elliptical orbit 2.1.1.3 parabolic orbit Eccentricity e satisfies the condition e = 1 track. 2.1.1.4 hyperbolic orbit Eccentricity e satisfies the condition e > track 1. 2.1.2 Classification by orbital inclination 2.1.2.1 anterograde track Inclination i satisfying the condition 0 ° ≤i < orbit of 90 °. 2.1.2.2 retrograde orbit 2.1.2.3 polar orbit Inclination i satisfies the condition i = orbit of 90 °. Generally close to 90 ° inclination orbit, also known as polar orbits. Polar orbit referred to as polar orbit. 2.1.3 Classification by orbital altitude 2.1.3.1 Low Orbit Low orbital altitude orbit, orbital altitude is usually lower than 2000km. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 29079-2012_English be delivered?Answer: Upon your order, we will start to translate GB/T 29079-2012_English as soon as possible, and keep you informed of the progress.
