High level definitions to work with GNSS in Rust

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

Add "gnss" to your Cargo.toml

gnss-rs = "2"

Import "gnss-rs":

extern crate gnss_rs as gnss;

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);

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));

Other definitions and features exist. Use compilation options (crate features) to unlock them. The idea is to maintain a very minimal default library.

• The SERDE features unlocks serialization/deserialization of the main structures defined here.

• The DOMES features unlocks the definition of DOMES GNSS/IGS reference station, that are widely used in GNSS data processing. This number identifies a station uniquely.

• The COSPAR features unlocks the definition of the COSPAR (Launch) ID number. This number identifies the launch of a vehicule uniquely. It is used in RINEX and other files format.

• The SBAS feature will create a static database that defines each SBAS service areas, projected on ground as WKT/GEO objects, with one method to select a SBAS service based on Latitude and Longitude coordinates.

Many libraries exist nowadays to process GNSS data or perform typical GNSS processing tasks.
Amongst them, be sure to checkout:

• Nyx: Orbital navigation
• ANISE: Earth orientation modeling and Orbital navigation
• Rtk-rs: Precise Point Positioning, related calculations and modeling
• RINEX: files processing and management
• SP3: files processing and management
• Hifitime: Timescale and related calculations
• CGGTTS: files production and processing
