GNSS
High level definitions to work with GNSS in Rust
- Space Vehicles definitions:
SV
- GNSS Constellations:
Constellation
- GNSS Timescales:
Constellation.timescale()
Getting started
Add "gnss" to your Cargo.toml
gnss-rs = "2"
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));
Other definitions and features
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.
Relevant Ecosystems
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
