There is a wide range of electronics available on the market today for generating satellite navigation signals that create artificial positions, especially for game apps on smartphones. These electronics can be dangerous because they could interfere with all satellite receivers in a larger radius without being noticed. GOOSE, in contrast, has already access to the OS-NMA service (Open Service Navigation Message Authentication) of the Galileo satellite navigation service, which will not be officially available until 2020. This service transmits Galileo satellite signals with an encryption that makes it considerably more difficult to pretend a position. This means that the vehicle can continue to be provided with a reliable position in the future.
