Environment

General atmospheric profiles such as ISA, COESA; nonstandard day simulations; lapse rate atmosphere; pressure altitude

Use environment-standards-based reference models to model standard atmospheric, gravity, and magnetic field profiles. Use ephemeris data to calculate position and velocity of celestial bodies.

Visualizing World Magnetic Model Contours for 2015v2 Epoch

Visualize contour plots of the calculated values for the Earth's magnetic field using World Magnetic Model 2015v2 (WMM2015v2) overlaid on maps of the Earth. WMM2015v2, released by NOAA in February of 2019, addresses degraded performance of WMM2015(v1) in the Arctic region and supersedes it. For more information about the WMM2015v2 release, see https://www.ncei.noaa.gov/news/world-magnetic-model-out-cycle-release.

Visualizing Geoid Height for Earth Geopotential Model 1996

Calculate the Earth's Geoid height using the EGM96 Geopotential Model of the Aerospace Toolbox™ software. It also shows how to visualize the results with contour maps overlaid on maps of the Earth. The Mapping Toolbox™ and Simulink® 3D Animation™ are required to generate the visualizations.

Estimate Sun Analemma Using Planetary Ephemerides and ECI to AER Transformation

Estimate the analemma of the Sun. The analemma is the curve that represents the variation of the angular offset of the Sun from its mean position on the celestial sphere relative to a specific geolocation on the Earth surface. In this example, the analemma is estimated relative to the Royal Observatory at Greenwich, United Kingdom. After the estimation, the example plots the analemma.
