PreviSat

PreviSat is your go-to satellite tracking software that helps you keep an eye on artificial satellites in real time. Whether you're a space enthusiast or just curious, this tool is here to make satellite watching easy and fun!

Real-Time Satellite Monitoring

With PreviSat, you can see satellites on a world or sky map. It offers predictions about when satellites will pass by and even alerts for Iridium flares. How cool is that?

Useful Features at Your Fingertips

This software comes with a bunch of handy parameters to gather all the important info about satellite positions across different frames. You'll get details like osculating elements (that's just fancy talk for Keplerian orbital elements), TLE (two-line element) sets to compute positions, and more.

Observation Modes

You can track satellites in two ways: in real-time or by manually setting the time for viewing their positions. This flexibility means you can enjoy observing whenever it suits you!

Comprehensive Satellite Info

Want to know the nitty-gritty? PreviSat gives you detailed information about each satellite's position in various frames, like terrestrial and equatorial. Plus, you'll find out its velocity, brightness, dimensions, and even where the Sun and Moon are located during its pass.

Calculating Passes Made Easy

The program lets you calculate when artificial satellites will be visible from anywhere on Earth! You just specify things like start and end dates, location details, and elevation levels. The results can be exported as TXT files—super handy!

Irridium Flares & Orbital Events

You can also determine Iridium flares for specific locations! You'll see terrestrial coordinates right next to your observation spot when the flare is at its peak. Plus, it calculates orbital events and ISS transits with the Sun or Moon.

TLE Management Simplified

PreviSat allows you to manage TLE orbital elements easily by updating them online or uploading data from TXT or GZ files.

User-Friendly Location Management

You can choose from several location categories and add or delete locations as needed. Want to declutter? Just hide any elements on the map like Sun positions or satellite names.

Your Reliable Satellite Observer

In short, PreviSat is a reliable app packed with powerful features to help you observe artificial satellites effortlessly!
