Todd Humphreys: How to fool a GPS

The video discusses the evolution of GPS technology, highlighting a significant change in 2000 that improved accuracy from football field-sized errors to room-sized errors. This advancement led to innovations like in-car navigation. The speaker predicts a future with hyper-precise GPS, enabling applications like augmented reality. However, the rise of GPS dots raises privacy concerns, as tracking becomes easier. The video also explores GPS jammers and spoofers, which can disrupt signals, posing security risks. The speaker emphasizes the need to balance privacy with technological progress.

What was the significant change in GPS accuracy ordered by President Bill Clinton in 2000?

• Errors reduced from the size of a football field to a small room

• GPS became available only to military personnel

• GPS signals were encrypted for civilian use

• Errors increased from the size of a small room to a football field

What is the potential accuracy level that can be achieved by paying attention to the carrier phase of the GPS signal?

• Meter-level accuracy

• Centimeter-level accuracy

• Kilometer-level accuracy

• Foot-level accuracy

What is a GPS dot?

• A device that provides two-meter accuracy

• A highly accurate tracking device within two feet

• A type of GPS receiver used in cars

• A GPS signal jammer

What legal challenge did Carol face when trying to disable the GPS tracker on her car?

• The FBI confiscated her car

• The police were unable to find the device

• The GPS tracker was legal to use

• The mechanic refused to check the car

What is a Wave Bubble?

• A GPS signal receiver

• To track multiple GPS devices simultaneously

• To encrypt GPS signals for security

• To enhance GPS signal strength

What is a potential consequence of GPS spoofing?

• Enhanced GPS security

• Chaos in navigation systems

• Increased GPS signal range

• Improved GPS accuracy

What ethical dilemma is associated with GPS spoofing?

• Choosing between GPS accuracy and cost

• Balancing privacy with reliable GPS signals

• Deciding on GPS signal encryption

• Selecting GPS devices for public use

What is the 'invisible utility' referred to in the context of GPS?

• The reliance on GPS for navigation

• The encryption of GPS signals

• The miniaturization of GPS devices

• The use of GPS in military operations
