A satellite ground track or satellite ground trace is the path on the surface of a planet directly below a satellite's trajectory. It is also known as a suborbital track or subsatellite track , and is the vertical projection of the satellite's orbit onto the surface of the Earth (or whatever body the satellite is orbiting).

The .GPX data file recorded during the drawing process is then visualised, usually overlaying it as a line on a map of the area. Artists usually run or cycle the route—while cars, vans, boats and aeroplanes are utilized to create larger pieces. The first known GPS drawing was made by Reid Stowe in 1999. "Voyage of the Turtle" is an ocean ...
A whisk broom or spotlight sensor, also known as an across-track scanner, is a technology for obtaining satellite images with optical cameras. [1] It is used for passive remote sensing from space. In a whisk broom sensor, a mirror scans across the satellite ’s path ( ground track ), reflecting light into a single detector which collects data ...
A satellite navigation device or satnav device, also known as a satellite navigation receiver or satnav receiver or simply a GPS device, is a user equipment that uses satellites of the Global Positioning System (GPS) or similar global navigation satellite systems (GNSS). A satnav device can determine the user's geographic coordinates and may ...
Automatic Tracking Satellite Dishes are satellite dishes used while a vehicle, boat or ship is in motion. Automatic tracking satellite dishes utilize gyroscopes , GPS position sensors, and uses unique satellite identification data and an integrated DVB decoder to aid in identification of the satellite that it is pointing at.

A GPS tracking unit, geotracking unit, satellite tracking unit, or simply tracker is a navigation device normally on a vehicle, asset, person or animal that uses satellite navigation to determine its movement and determine its WGS84 UTM geographic position (geotracking) to determine its location.

When a satellite's orbit is being adjusted, the satellite is marked unhealthy, so receivers do not use it. After the maneuver, engineers track the new orbit from the ground, upload the new ephemeris, and mark the satellite healthy again. The operation control segment (OCS) currently serves as the control segment of record.
