現在的太空船,衛星, 是否不須用陀螺儀定位?

文章 vr2xsc » 週四 24 9月, 2015 10:44

Just confirmed by a well known Space scientist (Wiley), his answer to my questions as follow. 1. "There is no needed for any Gyro system remain on-board for any space vehicle which is not decided to reenter Earth safely." 2. "Most Deep Space vehicles were using Deep Space Network and Laser guidance system for direction, rotation, speed verification, aim their antennas back to earth for transmission and...etc but mainly responds to by remote commands from Earth commanding station(s). 4. Some new technologies were developed and deployed such as Smart Planet Laser Identification Systems(SPLIS), were done and deploy since 2001."

我是否outdate 了 :?

If my memory is still functioning, orbiters have started gyro-less opertations since late 1990s.

vr2xsc Sir:

現時人造衛星仍有使用陀螺儀。陀螺儀與各種電磁波感應器 (包括紅外地球感應器,太陽感應器,恒星感應器,磁強度計及射頻感應器) 組成姿態測量儀,其中陀螺儀提供衛星初步姿態信息,再由其他電磁波感應器提供校準信號修正陀螺儀的測量誤差。

Examples of gyroless operations:

1. SOHO see: http://umbra.nascom.nasa.gov/soho/gyroless.html

2. Rosetta see: http://naif.jpl.nasa.gov/pub/naif/pds/d ... P_3226.PDF

3. ERS2 see: http://www.esa.int/Our_Activities/Opera ... _gyro-less

gyro-less / gyroless = 不使用陀螺儀
