Vulcan User Guides

Welcome to the Vulcan user guides. These documents provide detailed usage instructions for each module with code examples, API references, and links to interactive demos.

Modules

Guide	Description
Atmosphere	US Standard Atmosphere 1976 - temperature, pressure, density
Coordinates	ECEF, LLA, NED frames and geodetic conversions
Frame Graph	Hierarchical frame tree with extensible transform providers
Rotations	Euler angles, quaternions, DCMs, axis-angle
Time	Epochs, time scales (TAI, TT, UTC, GPS), leap seconds
Wind	Wind shear, Dryden and von Kármán turbulence models
Gravity	Point mass, J2, J2-J4 gravity models
Aerodynamics	Dynamic pressure, Mach, Reynolds number
Sensors	IMU noise models - Allan variance, Markov, random walk
RNG	Random number generation utilities for Monte Carlo

Getting Started

If you're new to Vulcan, start with the Getting Started example which demonstrates:

1. Basic atmospheric queries
2. Coordinate transformations
3. Symbolic computation with Janus

#include <vulcan/vulcan.hpp>
 
// All Vulcan modules available via single include
auto atm = vulcan::ussa1976::state(10000.0);
auto wind = vulcan::wind_shear::power_law(100.0, 10.0, 10.0);
