Gps Satellite Orbit Tracking

Secretive chinese launch sends two remote sensing satellites into orbit china added to its earth observation capabilities with the clandestine launch of two satellites from taiyuan late saturday.

Gps satellite orbit tracking.

See stuff in space on github. They use the iridium and globalstar low earth orbit satellite networks which are generally used for communication because they take less energy and have far less lag time than gps. You can expect a more reliable solution when you track more satellites. The satellites in the gps constellation are arranged into six equally spaced orbital planes.

Gps satellites fly in medium earth orbit meo at an altitude of approximately 20 200 km 12 550 miles. Satellite maneuvers are not precise by gps standards so to change a satellite s orbit the satellite must be marked unhealthy so receivers don t use it. This means that the same satellite reaches a certain position about 4 minutes earlier each day. The 31 satellites that currently make up the gps space segment are orbiting the earth about 12 000 miles above us.

Each satellite circles the earth twice a day. Azimuth and elevation are the local coordinates and they inform the position on the sky where the observer should look to see the satellite or to point out his antenna. Period is the time that the satellite takes to complete an orbit around the earth counted from perigee to perigee. Altitude is the.

Indicates the amount in kilometers existing between the observer and the satellite. Enlarge expandable 24 slot satellite constellation as defined in the sps performance standard. Stuff in space is a realtime 3d map of objects in earth orbit visualized using webgl. Guides to the night sky.

In this page you can track in real time all the satellites orbiting the earth with both 2d and 3d interactive representations predict their passes view their trajectory among stars on an interactive sky chart predict satellite flares and transits across the sun and the moon find out the best location to see these events on a detailed google map. The gps satellite system. You could be tracking nearly 20 with newer garmin products. After the satellite maneuver engineers track the new orbit from the ground upload the new ephemeris and mark the satellite healthy again.

A world map of the positions of satellites above the earth s surface and a planetarium view showing where they appear in the night sky. Gps satellite positions find bright satellite passes objects.
