Positioning Tutorial - sptort.orbital7

Getting Started with Positioning

Step 1

Initialize your positioning session using the SPTORT API. This example demonstrates how to request current orbital position.

// Initialize position tracking
POST https://api.sptort-orb.com/v3/position/start
Content-Type: application/json
Authorization: Bearer <your_token>

{
  "satelliteId": "Sat-OS-123",
  "ephemeris": "JPL-2025-0075",
  "frame": "ITRF 2025"
}

Step 2

Monitor live position updates using a streaming endpoint for millisecond-accurate tracking.

GET https://api.sptort-orb.com/v3/position/stream
Content-Type: text/event-stream
Authorization: Bearer <your_token>

// You'll receive continuous updates in SSE format:
event: position
data: {
  "latitude": 37.7749,
  "longitude": -122.4194,
  "altitude": 35784,
  "timestamp": "2025-08-20T00:00:00Z"
}

Coordinate Systems Overview

Earth Centered Inertial (ECI)

Used for orbital mechanics calculations with respect to fixed stars.

Earth Centered Earth Fixed (ECEF)

Rotating Earth-based coordinate system for surface tracking.

Orbital Frame

Dynamic coordinate system that follows orbital motion vectors.

Optimize Positioning Accuracy

Multi-GNSS Support

GPS + GLONASS fusion for redundancy
Galileo + Beidou integration

Time Synchronization

UTC and TAI time references
Spacecraft reference clocks

Ensure all timestamps use ISO 8601 with time zone

Advanced Positioning Techniques

Relativity Corrections

Apply gravitational and SR/GR corrections for high-precision orbit calculations.

Multi-Frequency Solutions

Use L1/L2/L5 channels in dual and tri-band tracking for ionospheric compensation.

Kalman Filtering

Real-time dynamic filtering of measurement noise and system drift.
