LH frame is obtained from the ECEF
frame through the following rotations: [mathematical expression not reproducible].
Early childhood education for sustainability (ECEfS
) has been nationally and globally recognised as having the potential to nurture caring, capable and responsible citizens, by providing children with knowledge about sustainability problems, a voice in decision-making about these issues and the skills to do something about it (Davis & Elliott, 2014; Pramling Samuelsson & Kaga, 2008).
where xyz stand for the coordinates in WGS84, and blh stand for the coordinates in ECEF
Enhancing customer experience through business process improvement: An application of the enhanced customer experience framework (ECEF
The user coordinates are in the rotating Earth-fixed frame (ECEF
Obtainment of Satellites' Coordinates in ECEF
. With the almanac files supplied by the website of navcen.uscg.gov and actually broadcasted by GPS satellites, the real-time coordinate of all satellites in orbit are calculated; then the coarse precision satellites' tracks can be obtained.
The World Geodetic System 1984 (WGS84) is used for the geodetic reference and Earth-centred Earth-fixed (ECEF
) is the Cartesian coordinate frame of reference used in GPS.
This section explains the detailed DDM simulation process which includes three steps: 1) determine the location of the glistening zone surrounding the Specular Point (SP) in the Earth-Centered, Earth-Fixed (ECEF
) coordinate System .
The nominal position of the observation site is (-1507932.6167, 6195587.6757, 148897.9990) in the earth-centered, earth-fixed (ECEF
) Cartesian coordinate system .
The position and velocity components of GLONASS satellites, taken from the navigation message, are re-computed from ECEF
(Earth Centered, Earth Fixed) Greenwich coordinate system (PZ-90.02) to an absolute coordinate system.
