@rotastellar/sdk

Node.js SDK for RotaStellar — Space Computing Infrastructure

Core types, utilities, and client for the RotaStellar platform.

Installation

npm install @rotastellar/sdk

Quick Start

import { Position, Orbit, Satellite, TimeRange } from '@rotastellar/sdk';

// Create a geographic position (e.g., Kennedy Space Center)
const ksc = new Position({
  latitude: 28.5729,
  longitude: -80.6490,
  altitudeKm: 0.0
});
console.log(`KSC: ${ksc.latitude}°N, ${ksc.longitude}°W`);

// Define an ISS-like orbit
const orbit = new Orbit({
  semiMajorAxisKm: 6778.0,
  eccentricity: 0.0001,
  inclinationDeg: 51.6,
  raanDeg: 100.0,
  argPeriapsisDeg: 90.0,
  trueAnomalyDeg: 0.0
});
console.log(`Orbital period: ${orbit.periodMinutes.toFixed(1)} minutes`);
console.log(`Apogee: ${orbit.apogeeKm.toFixed(1)} km`);

// Create a satellite
const satellite = new Satellite({
  id: 'ISS',
  name: 'International Space Station',
  noradId: 25544,
  position: new Position({ latitude: 45.0, longitude: -122.0, altitudeKm: 408.0 }),
  orbit
});

// Define a time range
const range = new TimeRange({
  start: new Date('2026-01-01T00:00:00Z'),
  end: new Date('2026-01-02T00:00:00Z')
});
console.log(`Duration: ${range.durationHours.toFixed(1)} hours`);

Features
