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 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.

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.

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.

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.
