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 2015 Epoch

Visualizing World Magnetic Model Contours for 2015 Epoch

This example shows how to visualize contour plots of the calculated values for the Earth's magnetic field using World Magnetic Model 2015 (WMM-2015) overlaid on maps of the Earth. The Mapping Toolbox™ software is required to generate the maps of the Earth.

Visualizing Geoid Height for Earth Geopotential Model 1996

Visualizing Geoid Height for Earth Geopotential Model 1996

This example shows how to 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.

Marine Navigation Using Planetary Ephemerides

Marine Navigation Using Planetary Ephemerides

This example shows how to use the planetary ephemerides and a Earth Centered Inertial to Earth Centered Earth Fixed (ECI to ECEF) transformation to perform celestial navigation of a marine vessel.

Estimate Sun Analemma Using Planetary Ephemerides and ECI to AER Transformation

Estimate Sun Analemma Using Planetary Ephemerides and ECI to AER Transformation

This example shows how to 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.
