Usage

• Add astroz as a dependency in your build.zig.zon.

zig fetch --save https://github.com/ATTron/astroz/archive/<git_tag_or_commit_hash>.tar.gz
#or
zig fetch --save git+https://github.com/ATTron/astroz/#HEAD

• Use astroz as a module in your build.zig.

const astroz_dep = b.dependency("astroz", .{
    .target = target,
    .optimize = optimize,
});
const astroz_mod = astroz_dep.module("astroz");
exe.root_module.addImport("astroz", astroz_mod);

Examples

Orbital Mechanics

• Planet Transfer & Mission Planning

  Demonstrates interplanetary transfers with mission planning (Hohmann vs Bi-Elliptic comparison) and trajectory propagation.

• Orbit Maneuvers

  Comprehensive example showing TLE-based orbit propagation with various maneuver types: impulse, plane change, and phase change.

• Monte Carlo Simulation

  Statistical analysis for mission planning with uncertainty.

Spacecraft Operations

• Parse TLE

  Parse Two-Line Element sets for satellite orbit information.

• Orbit Orientation Determination

  Calculate spacecraft attitude and orientation.

Telemetry & Data Handling

• Parse Vita49 / with Callback

  VITA Radio Transport (VRT) packet stream parsing.

• Parse CCSDS / with File Sync

  Parse CCSDS space packet protocol from files.

• Create CCSDS Packet / with Config

  Generate CCSDS packets for telemetry.

Astronomy & Astrometry

• Generate Image from FITS File

  Parse and render FITS astronomical image data.

• Precess Star Coordinates

  Calculate stellar precession to a target epoch.

• Calculate WCS from TLE

  Compute World Coordinate System values from orbital elements.
