WebTHE SEZ, SOUTH-EAST-ZENITH, COORDINATE FRAME. The SEZ coordinate frame, sometimes called the Topocentric Horizon Coordinate System, will be used to define the satellite’s initial location. It is shown in the figure below. South-East-Zenith (SEZ) Coordinate Frame. Now, we will consider a side view of the satellite in orbit (note: not to scale): WebApr 11, 2024 · Topocentric ITRS frames are convenient for observations of near Earth objects where stellar aberration is not included. One can merely subtract the observing site’s EarthLocation geocentric ITRS coordinates from the object’s geocentric ITRS coordinates, put the resulting vector into a topocentric ITRS frame and then transform to AltAz or …

Web2. (30 points) Figure below shows the station-based topocentric-horizon coordinate system, which consists of three orthogonal axes: the S axis points south along a local meridian, E points east along a line of latitude, and Z points straight up (in the opposite direction of Earth's center). The horizon plane formed by the S and E axes is the fundamental plane of … http://tdc-www.harvard.edu/IOTA/Publi/Memos/pointing.pdf lachlan deakin anu
