Crate nav_types

Easily work with global positions and vectors.

This crate is intended to allow easy and safe interoperability between different global position and vectors in different coordinate systems. The create is built on top of nalgebra and strives to be compatible with types from that crate.

Example

use nav_types::ECEF;
use nav_types::ENU;
use nav_types::NED;
use nav_types::WGS84;

// Define positions using latitude and longitude on the WGS84 ellipsoid
let oslo = WGS84::new(59.95, 10.75, 0.0);
let stockholm = WGS84::new(59.329444, 18.068611, 0.0);

println!("Great circle distance between Oslo and Stockholm: {:?}",
    oslo.distance(&stockholm));

// Calculate vectors between positions
let vec = ECEF::from(stockholm) - ECEF::from(oslo);
println!("Vector between Oslo and Stockholm: {:?}", vec);

// Easily convert between ENU and NED vectors
let ned_vec = NED::from(vec);

// Add vectors to positions
let stockholm_2 = ECEF::from(oslo) + vec + ENU::new(0.0, 10.0, 0.0);
