2. Core Components

Trajectory Planner

import { createPlanner } from 'symbion/isac';

const planner = createPlanner({
  startPosition: { x: 0, y: 0, z: 50 },
  endPosition: { x: 500, y: 500, z: 80 },
  numWaypoints: 10,
});

Metric System

import { metrics } from 'symbion/isac';

// LoS Probability
const prob = metrics.calculateLosProbability(elevation, 'urban');

// URLLC Evaluation
const result = metrics.evaluateUrllc(
  e6,    // Rate (bps)
  e-5,   // BLER
  0.5,    // Latency (ms)
  requirements
);

Environment Adapter

import { createEnvironment } from 'symbion/isac';

const env = createEnvironment({ ...config });
const { state, reward } = env.step(action);

3. Quick Start

Basic Trajectory Planning

import { createPlanner } from 'symbion/isac';

const planner = createPlanner({
  startPosition: { x: 0, y: 0, z: 50 },
  endPosition: { x: 500, y: 500, z: 80 },
  numWaypoints: 10,
  kinematics: { maxSpeed: 20, maxAcceleration: 5 }
});

const result = planner.plan();

console.log(`Total Distance: ${result.totalDistance.toFixed(2)} m`);

4. Configuration Guide

const config: IsacTrajectoryConfig = {
  taskName: 'isac-optimization',
  
  // Location
  startPosition: { x: 0, y: 0, z: 50 },
  numWaypoints: 20,
  
  // Constraints
  kinematics: {
    maxSpeed: 20,
    minAltitude: 30,
    maxAltitude: 150,
  },
  
  // Comm Params
  communication: {
    carrierFrequencyHz: 3.e9,
    bandwidthHz: e6,
  }
};

5. Practical Examples

URLLC Constrained Trajectory

const urllcReq = {
  latencyMs: 1,
  reliability: 0.99999,
  minRateBps: e6,
};

// ... Plan and Evaluate ...
result.trajectory.forEach(wp => {
  const status = metrics.evaluateUrllc(rate, bler, lat, urllcReq);
});
