chrono::sensor::ChGPSSensor Class Reference

Description

GPS class.

This class uses the reference location of a simulation and spherically maps the cartesian space simulation onto a sphere, calculating the latitude, longitude, altitude relative to the Earth's surface. The reference location defines what GPS coordinates are associated with the origin of the simulation. The mapping is performed such that the +Z-axis points up, +X-axis points East, and the +Y-axis points North.
