While committing a crime is certainly not within a legitimate expectation of privacy, if the cell site location data could place him near those scenes, it could place him near any other scene," the court writes. "There is a reasonable privacy interest in being near the home of a lover, or a dispensary of medication, or a place of worship, or a house of ill repute.

Warrantless cellphone location tracking is illegal, US circuit court rules | The Verge

The deputy prime minister, Dmitri O. Rogozin, said that as of Sunday the GPS base stations in Russia could not be used for military purposes, and he announced a deadline of Sept. 1 for the United States to agree to allow base stations on its territory for Russia’s navigation system, Glonass. Otherwise, he said, the GPS terminals would be shut down for good.

In GPS Battle, Russia Sets Restrictions of Its Own - NYTimes.com

An appellate court has finally supplied an answer to an open question left dangling by the Supreme Court in 2012: Do law enforcement agencies need a probable-cause warrant to affix a GPS tracker to a target’s vehicle? The Third Circuit Court of Appeals gave a resounding yes to that question today in a 2 to 1 decision. “Today’s decision is a victory for all Americans because it ensures that the police cannot use powerful tracking technology without court supervision and a good reason to believe it will turn up evidence of wrongdoing,” said ACLU attorney Catherine Crump in a statement. “These protections are important because where people go reveals a great deal about them, from who their friends are, where they visit the doctor and where they choose to worship.”

Texas students fake GPS signals and take control of an $80 million yacht

In the good old days spoofing meant a Mad magazine article on a television show.

No longer. In the world of secure (and insecure) networks, the act of spoofing entails faking data to take advantage of network insecurity. And as some University of Texas students led by professor Todd Humphreys have shown, it is now possible to spoof a GPS system.

That is, the students created a device that sent false GPS signals to a ship, overrode the existing GPS signals, and essentially gained control of the navigation of an $80 million yacht in the Mediterranean Sea.

China's Beidou GPS-substitute opens to public in Asia

China has opened up its domestic sat-nav network to commercial use across the Asia-Pacific region.

Beidou - named after the Chinese word for the Big Dipper constellation - offers an alternative to the US’s global positioning system (GPS).

It had previously been restricted to the Chinese military and government.

A spokesman said that Beidou is targeting a 70-80% share of the Chinese market in related location services by 2020.

The China Satellite Navigation Office added that by that time it also intended the service to be available across the globe.

Feds Say Mobile-Phone Location Data Not 'Constitutionally Protected'

The Obama administration told a federal court Tuesday that the public has no “reasonable expectation of privacy” in cellphone location data, and hence the authorities may obtain documents detailing a person’s movements from wireless carriers without a probable-cause warrant.

The administration, citing a 1976 Supreme Court precedent, said such data, like banking records, are “third-party records,” meaning customers have no right to keep it private. The government made the argument as it prepares for a re-trial of a previously convicted drug dealer whose conviction was reversed in January by the Supreme Court, which found that the government’s use of a GPS tracker on his vehicle was an illegal search.

New Satellites Could Make GPS Harder to Jam

Without GPS, drones can’t fly, communications networks can’t function, and you don’t have a chance of figuring out how to get to your Aunt Sadie’s place in New Jersey. And right now, GPS is highly vulnerable because its weak signals are coming from an aging constellation of satellites.

Lockheed Martin, the nation’s biggest military contractor, thinks the next generation of GPS satellites might be able to fix all that. GPS III, as it’s known, is designed to improve the accuracy of the GPS signal and have better resistance to jamming. Also, it is meant to be compatible with its international alternatives like the European Galileo system or the Russian GLONASS system. Potentially, it will improve GPS’ accuracy and resistance to jamming — the deliberate or accidental transmission of radio signals that interfere with regular communications.

The core problem is that we’ve got a GPS infrastructure which is based on a security architecture out of the 1970s,” Scott tells Danger Room. “From a security point of view, if you look at GPS’s current status, is more or less equivalent to operating computers without firewalls, with no basic checks.

BAE Systems' Navsop navigation system rivals GPS

A new positioning system has been developed to complement or even replace current technologies such as GPS.

Made by UK defence firm BAE Systems, it relies on the same signals used by mobile phones, TVs, radios and wi-fi rather than navigation satellites.

The firm says Navsop could help find victims inside buildings during a fire and locate stolen vehicles hidden in underground car parks.

It could also be used in a war if the sat-nav system was turned off.

It is no longer valid to assume that the cell sector recorded by the network will give only an approximate indication of a user’s location,” Blaze writes in his testimony. “The gap between the locational precision in today’s cellular call detail records and that of a GPS tracker is closing, especially as carriers incorporate the latest technologies into their networks. As the precision provided by cellular network-based location techniques approaches that of GPS-based tracking technology, cellular location tracking can have significant advantages for law enforcement surveillance operations over traditional GPS trackers.
