When radar stations on the Earth monitor the location and movements of satellites, they are said to be tracking the satellites.
Satellite tracking devices are best used to locate vehicles in real time. This technology can be useful to companies for tracking shipments. Satellite tracking device can also be useful if you have it installed in your vehicle and your vehicle is stolen. The following website offers some detail as to how this technology works, http://en.wikipedia.org/wiki/Tracking_device
Tracking and Data Relay Satellite
You can find satellite tracking devices at any electronic store such as Best Buy or Circuit City. Also, you can always buy them online, for best deals.
Here's a link to a website that offers a lot of interesting information to learn about GPS satellite tracking. http://www.edu-observatory.org/gps/tracking.html
Yes. As Stated at http://www.liveviewgps.com/gps+satellite+tracking+.html, they are legal and available to the public, for a price of course. You also need proper equipment in order for it to function properly.
Satellite Tracking for Asia Region
GPS tracking on your phone hooks up to a satellite. In case of emergency and 911 is called they use a satellite system to be able to pin point exactly where you are.
A satellite dish tracking a geosynchronous satellite would remain fixed in a specific direction, as geosynchronous satellites maintain a constant position relative to the Earth's surface. In contrast, a dish tracking a satellite in low Earth orbit would need to move continuously to follow the satellite's rapid movement across the sky, as these satellites orbit the Earth at much lower altitudes and complete an orbit in about 90 minutes. Thus, the motion of the dish can indicate the type of satellite being tracked.
Take a look at the link below from NOLA.com. It has links to satellite views and news about Hurricane Gustav.
South Africa's Council for Scientific and Industrial Research Satellite Applications Centre is a satellite tracking facility located in Hartebeesthoek, 60 kilometres north of Johannesburg.
I would say they are both highly advanced and are used for tracking things/people but a satellite is more advanced with being able to live in and what not
