Q 2.12 Can satellites track mobile phones?

Satellites are not used for tracking any particular mobile phone.

Mobile phones estimate their own position from signals transmitted by satellite navigation systems such as GPS and GLONASS. The location information, stored within the phone, can be transmitted to another user by an application thus revealing its location.Location of a mobile can be tracked through terrestrial mobile systems using technique such as triangulation and other techniques available only to law enforcement agencies. Nevertheless, location of a mobile’s resident cell is always known by the network since the mobile continually updates its position at a cell level.
