ISS Location

We offer both a free and basic web-based satellite tracking application and a more sophisticated graphical and integrated full-featured application based upon Windows UWP. With the web-based tracking application any web-browser running on an Android, Linux, or iPhone should work. The UWP application runs on Windows 10+ desktops and devices. Give it a try, it is free - just follow the above links! Most people are tracking the International Space Station (ISS).

Es'hail 2 QO-100

The Es'hail 2 QO-100 is now available for use with amateurs! It is the first geosynchronous amateur radio satellite.

SpaceX Starlink Constellation

The first 60 of the SpaceX Starlink Constellation satellites were launched in May 2019. More are planned to be launched in the following years for a constellation of about 12,000 satellites.

Tesla Roadster

SpaceX's Tesla roadster with SpaceMan were being tracked before rocket and car went into a non-earth orbit.

AO-92 Fox1D

The AO-92 Fox 1D satellite is very popular for amateurs.

AO-7 Oscar 7

AO-7 Oscar 7 has been in use by amateurs for several decades now.

Low Earth Orbit (LEO)

A low Earth orbit (LEO) is an orbit around Earth with an altitude between 160 km (99 mi) and 2,000 km (1,200 mi). LEO demonstrate an orbital period of between about 84 and 127 minutes. Orbital decay is experienced when objects are below approximately 160 km (99 mi) primarily due to atmospheric drag.

Medium Earth Orbit (MEO)

A medium Earth orbit (MEO) is an orbit around Earth with an altitude between 2,000 km (1,200 mi) and 35,786 km (22,236 mi). Medium Earth orbit's demonstrate an orbital period between about 2 and 24 hours. MEO's are sometimes called intermediate circular orbit (ICO).

High Earth Orbit (HEO)

A high Earth orbit (HEO) is an orbit around Earth with an altitude above geosynchronous orbits at 35,786 km (22,236 mi). High Earth orbit's demonstrate an orbital period greater than 24 hours. High Earth orbit’s exhibit an apparent retrograde motion. The Earth’s rotation speed is faster than the objects making the objects ground track to appear to be moving westward compared to the Earth.

Geostationary Earth Orbit (GEO)

A geostationary orbit, geostationary Earth orbit, or geosynchronous equatorial orbit (GEO) is an orbit around earth that is circular at 35,786 km (22,236 mi) above the Earth’s equator. An object in this type of orbit follows the Earth’s rotation. This means the orbit has an orbital period each to the Earth’s rotational period of one sidereal day. The object appears to motionless to an observer on Earth. The objects do make a small figure-8 ground track motion.

Highly Elliptical Earth Orbit (HEO)

A highly elliptical orbit (HEO) is an orbit around Earth where the object has a high eccentricity. Objects with this type of orbits have an extremely elongated path around the Earth. These types of orbits have an advantage that allow the object to be over parts of the earth for long periods of time. For this type of orbit, the apogee will be high and the perigee will be low. Other names for HEO orbits have been Molniya and Tundra orbits.

Lunar or Moon Orbit

This type of orbit depicts the orbit of the Earth's Moon. The Moon orbits the Earth at an altitude between 357,000 to 399,00 km.

Graveyard Orbit

A graveyard (junk or disposal) orbit is an orbit above geosynchronous orbits, above 35,786 km (22,236 mi). Objects are moved here one their operational life is over to avoid crashing into other objects and generating more space debris.

Tiangong 1 Tracking

The Chinese Tiangong 1 satellite reentered the earth's atmosphere and burned-up April 2, 2018. In memorance you can still psuedo-track using the last set of NORAD keplerian elements for the satellite. Click here for the simulation.

ISS Tracker

You can track the International Space Station (ISS) from you location using either our web-based or native application. Click here to track.

ISS Position

The International Space Station (ISS) orbits the earth with a inclination of 51.6429°. This means that space station will travel up to 51.6429° North and 51.6429° South. It's viewable footprint will of course go further in each direction. To see where it is exactly, click here to track.

ISS Sightings

The International Space Station (ISS) orbits the earth with a period of 92.6 minutes. This means it circles the Earth about every one and half hours. To see where it is exactly, click here to track.

ISS Live

You can view the video from the International Space Station (ISS) as it circles the Earth here. The video is also available when you are using our Windows based application Satelltie Tracking.

Live Real Time Satellite Tracking

Calculations are based upon the Keplerian Data Elements published by NORAD. The elements sets are accurate enough to be used to calculate and predict where the satellite will be in a live and realtime fashion as long as the orbit doesn't change too much. If the satellite's orbits perturbs enough, a new set of elements needs to be published to be very accurate, but older sets still can provide useful predictions. To see just click the button to download the application from the store. After the application downloads, you'll be tracking in just a few moments. It's easy and fun!

Spaces after period controversy?

Calibri (proportional font):   My son says one space after a period looks good at the end of a sentence (1 space next).  I say two spaces after the period is better. My son says one space after a period looks good at the end of a sentence (2 spaces next).   I say two spaces after the period is better.

Courier (mono-space font):   My son says one space after a period looks good at the end of a sentence (1 space next).  I say two spaces after the period is better. My son says one space after a period looks good at the end of a sentence (2 spaces next).   I say two spaces after the period is better.
