GPS Location Privacy

This page provides information about U.S. judicial rulings, legislation, and federal policies concerning GPS and personal privacy. It is not intended to influence or express opinions on any ongoing legal deliberations.

The government's GPS satellites are one-way beacons that cannot track you or anything on the ground. But commercially available GPS devices with communication or recording features can help users keep track of everything from vehicles and cargo to people and animals.

The use of GPS technology to covertly monitor the movements of suspects, employees, customers, and other people raises questions and concerns about individual privacy rights. Several lawsuits and legislative actions have sought to address these questions, but much remains unresolved today.

Judicial Rulings

The Fourth Amendment to the U.S. Constitution grants Americans certain privacy rights by protecting them from "unreasonable searches and seizures" and by requiring search warrants to be based on "probable cause." Read it...

As of November 2013, it is unclear whether the extended use of GPS devices to track suspects without a warrant violates their Fourth Amendment rights.

Supreme Court

Statue of Justice outside Supreme Court building In January 2012, the U.S. Supreme Court ruled that law enforcement must obtain a warrant before physically attaching a GPS tracking device to a suspect's vehicle. The decision (United States v. Antoine Jones) was based on a narrow application of the Fourth Amendment, since device installation involves physical intrusion on a suspect's vehicle. The Supreme Court did not resolve the broader issue of whether the Fourth Amendment protects geolocation privacy rights.

Lower Courts

A number of other federal and state courts have ruled on the use of GPS-based vehicle surveillance by law enforcement, both before and after the 2012 Supreme Court decision. However, several of the lower court opinions are in conflict, so the Supreme Court may need to revisit this topic in the future.

Revelant decisions issued after United States v. Jones include:

Congressional Legislation

Capitol dome Several U.S. states and non-U.S. jurisdictions have enacted laws establishing personal location privacy rights. However, current U.S. statute at the federal level does not provide clear protection of geolocation information.

Members of Congress have proposed legislation to prevent misuse of such information by law enforcement, companies, and individuals. These include the Geolocation Privacy and Surveillance Act ("GPS Act"), the Online Communications and Geolocation Protection Act, and the Location Privacy Protection Act.

As of November 2013, none of these bills has seen action beyond the committee level.

Federal Policies

Executive branch policies addressing GPS-related privacy issues are mostly decentralized across federal agencies. The following list of known, publicly available policies is a work in progress and not comprehensive.
