Crate gnss_rs

GNSS

High level definitions to work with GNSS in Rust

• Space Vehicles: SV
• GNSS Constellations: Constellation
• GNSS Timescales: Constellation.timescale()

Getting started

Add “gnss” to your Cargo.toml

gnss-rs = "2.1"

Import “gnss-rs”:

extern crate gnss_rs as gnss;

Space Vehicles

extern crate gnss_rs as gnss;

use gnss::sv;
use gnss::prelude::*;
use std::str::FromStr;
use hifitime::TimeScale;

let sv = SV::new(Constellation::GPS, 1);
assert_eq!(sv.constellation, Constellation::GPS);
assert_eq!(sv.prn, 1);
assert_eq!(sv.timescale(), Some(TimeScale::GPST));
assert_eq!(sv, sv!("G01"));
assert_eq!(sv.launched_date(), None);

SBAS support

We support SBAS (geostationary augmentations) systems.

extern crate gnss_rs as gnss;

use gnss::sv;
use gnss::prelude::*;
use std::str::FromStr;
use hifitime::{Epoch, TimeScale};

let sv = sv!("S23");
assert_eq!(sv.constellation, Constellation::EGNOS);
let launched_date = Epoch::from_str("2021-11-01T00:00:00 UTC")
    .unwrap();
assert_eq!(sv.launched_date(), Some(launched_date));
