GPS has become a widely deployed and useful tool for commerce, scientific uses, tracking, and surveillance. GPS's accurate time facilitates everyday activities such as banking, mobile phone operations, and even the control of power grids by allowing well synchronized hand-off switching. [88]
The use of GPS has been shown to have both positive and negative effects on spatial learning and memory. Research has shown that people who rely on GPS for navigation are less likely to develop and use mental maps and have a harder time remembering details about the environment, as GPS use can lead to a decline in those skills over time.

Geopositioning can be referred to both global positioning and outdoor positioning, using for example GPS, and to indoor positioning, for all the situations where satellite GPS is not a viable option and the localization process has to happen indoors. For indoor positioning, tracking and localization there are many technologies that can be used ...

The United States' Global Positioning System (GPS) consists of up to 32 medium Earth orbit satellites in six different orbital planes. The exact number of satellites varies as older satellites are retired and replaced. Operational since 1978 and globally available since 1994, GPS is the world's most utilized satellite navigation system.
GPS-based tracking system used for some individuals released from prison, jail or immigrant detention. According to a survey distributed by The Pew Charitable Trusts in December 2015, "the number of accused and convicted criminal offenders in the United States who are supervised with ankle monitors and other GPS-system electronic tracking devices rose nearly 140 percent over 10 years ...
GPS encodes this information into the navigation message and modulates it onto both the C/A and P(Y) ranging codes at 50 bit/s. The navigation message format described in this section is called LNAV data (for legacy navigation). The navigation message conveys information of three types: The GPS date and time, and the satellite's status.
A major subclass is made of geopositioning systems, used for determining an object's position with respect to Earth, i.e., its geographical position; one of the most well-known and commonly used geopositioning systems is the Global Positioning System (GPS) and similar global navigation satellite systems (GNSS).
