What is SPACEAPP & What does it Do?
Satellite trackers are digital tools that follow artificial objects orbiting Earth — like communication, weather, or research satellites. SPACEAPP is a satellite tracker reimagined for modern users: it collects orbital data from verified databases like NORAD and visualizes the real-time latitude, longitude, altitude, and speed of thousands of active satellites. Users can identify satellites, explore their missions, and even analyze their time spent in space through a clean, user-friendly interface.
We stopped supporting SPACEAPP v2.5, now, SPACEAPP v3.0/ v4.0/ v4.2 are available. See more here*

What is in our SPACEAPP?
Here’s a closer look at the core features that make SPACEAPP more than just a tracker — it’s a complete orbital insight platform built for exploration, research, and learning.
Satellite and NORAD ID
Each satellite in orbit is uniquely identified by a NORAD ID — a five-digit catalog number assigned by the North American Aerospace Defense Command. SPACEAPP lets you search and discover satellites by their common names or NORAD IDs. This helps users trace specific missions, verify authenticity, and explore satellite purpose (e.g., Starlink-1094 or NOAA-20).
Satellite Live Position
SPACEAPP tracks the precise latitude (North-South position) and longitude (East-West position) of satellites in real time. Our dynamic interface updates continuously so you can watch satellites as they move above countries, oceans, and continents. Perfect for learning orbital mechanics or spotting visible satellites from your location.
Satellite Orbit Data
Orbit data includes parameters like altitude, inclination, eccentricity, and revolution period. SPACEAPP calculates and displays these values so users can understand how high a satellite flies, what shape its orbit forms (circular or elliptical), and how frequently it circles Earth. Great for education and satellite operation modeling.
TLE data
TLE stands for Two-Line Element, a compact format used to predict a satellite’s position over time. SPACEAPP decodes and visualizes TLE data in human-friendly terms. You’ll learn how orbital data is stored, how satellite paths are calculated, and how NASA or NORAD can predict future positions using just two lines of numbers.
Satellite Speed
Satellites orbit Earth at incredible speeds — often between 7 to 8 km/s. SPACEAPP computes each satellite's current velocity based on its orbital data. This helps users compare low Earth orbit (LEO) vs. geostationary satellites and understand why some satellites move fast across the sky while others seem stationary.
Time In Space
How long has a satellite been in orbit? SPACEAPP calculates the duration since launch, so you can see if the satellite is newly deployed or decades old. Useful for understanding satellite lifespan, mission duration, and decay prediction.
Take a look at our SPACEAPP Versions
SPACEAPP v3.0 (Basic)
SPACEAPP v3.0 (BASIC) was our first stable release, offering multi-account support but only single-satellite tracking with no animations or map toggle. Performance is more limited compared to later versions.
- Pure plug-and-play: just run the .exe, no .env setup required.
- Register a free API key at n2yo.com/api and paste it inside the app when prompted.
- Supports multiple accounts for flexibility.
- Single satellite real-time tracking.
- No map toggle, fixed Earth view.
- No animations, focused on core functionality.
- Lightweight but slower compared to newer versions.
Note: Best for users who want the simplest version without extra features but please keep in mind that v3.0 has a few known issues (not critical) and will retire in December 2025.
SPACEAPP v4.0/v4.2 (RECOMMENDED)
SPACEAPP v4.x (PLUS/RECOMMENDED) introduced multi-tracking, smooth animations, and performance improvements while staying fully plug-and-play.
- Run instantly from the .exe, no extra setup files.
- Register a free API key at n2yo.com/api and paste it inside the app when prompted.
- Multi-account support with real-time satellite list monitoring.
- Track multiple satellites simultaneously.
- Smooth flying animations between selected satellites.
- Dual API modes (efficient 8s/call or faster 3s/call) and map toggle.
Note: v4.2 builds on v4.0 with small performance tweaks and automatic shortcut creation. It is the recommended version for most users.
Note: All SPACEAPP versions are pure plug-and-play, requiring no configuration — just download, run the executable, register your N2YO API key, and start tracking satellites.
