WIA-DEF-012

🔍 Overview

WIA-DEF-012 establishes comprehensive standards for Space Situational Awareness (SSA) systems, enabling detection, tracking, identification, and characterization of all objects in Earth orbit. This standard covers ground-based radar and optical sensors, space-based sensors, data fusion systems, and collision avoidance services to protect critical space assets and ensure orbital safety.

💻 API Example

import { SpaceSurveillance } from '@wia/def-012';

// Initialize SSA system connection
const ssa = new SpaceSurveillance({
  apiKey: process.env.SSA_API_KEY,
  catalog: 'comprehensive', // or 'active-only'
  alertLevel: 'high-priority'
});

// Query space object catalog
const satellites = await ssa.queryCatalog({
  filters: {
    objectType: 'active-satellite',
    orbit: 'LEO',
    country: ['USA', 'CHN', 'RUS'],
    launchDate: { after: '2020-01-01' }
  },
  fields: ['noradId', 'name', 'orbit', 'rcs', 'status']
});

console.log(`Found ${satellites.length} active LEO satellites`);

// Track specific object
const tracking = await ssa.trackObject({
  noradId: 25544, // ISS
  duration: 7, // days
  resolution: 'high' // high/medium/low
});

console.log(`Current position: ${tracking.position}`);
console.log(`Velocity: ${tracking.velocity} km/s`);
console.log(`Next ground station pass: ${tracking.nextPass}`);

// Conjunction analysis
const conjunctions = await ssa.analyzeConjunctions({
  primaryObject: 25544,
  timeWindow: 72, // hours
  threshold: 1000, // meters
  includeDebris: true
});

if (conjunctions.length > 0) {
  console.log(`WARNING: ${conjunctions.length} potential conjunctions`);
  conjunctions.forEach(conj => {
    console.log(`- TCA: ${conj.timeOfClosestApproach}`);

    console.log(`  Probability of collision: ${conj.probability}`);
    console.log(`  Secondary object: ${conj.secondaryObject.name}`);
  });
}

// Request maneuver recommendation
if (conjunctions.some(c => c.probability > 1e-4)) {
  const maneuver = await ssa.recommendManeuver({
    satelliteId: 25544,
    conjunction: conjunctions[0],
    constraints: {
      maxDeltaV: 5, // m/s
      preferredDirection: 'radial',
      minSafeDistance: 2000 // meters
    }
  });

  console.log(`Recommended maneuver:`);
  console.log(`- Delta-V: ${maneuver.deltaV} m/s`);
  console.log(`- Burn time: ${maneuver.burnTime} seconds`);
  console.log(`- Execute at: ${maneuver.executionTime}`);
}

// Subscribe to real-time alerts
ssa.subscribeAlerts({
  objects: [25544, 43013], // ISS and own satellite
  eventTypes: ['conjunction', 'maneuver', 'breakup', 'reentry'],
  callback: (alert) => {
    console.log(`ALERT: ${alert.type} - ${alert.message}`);
    // Trigger emergency response
  }
});
