Many satellite navigation applications require a reliable (i.e. secured, authenticated) positioning/timing solution. Often users might also want to tie a measurement or a piece of general information to secure positioning/timing information. To date, only Galileo PRS receivers have supplied this certainty, but PRS receivers also have limitations in terms of size, power input, availability and handling.
→ Need for a cost-effective, miniaturized and secure receiver solution
There are various commercial and authorized applications for the PRSauth technology:
At the European Satellite Navigation Competition ESNC 2012, Alexander Rügamer and Manuel Stahl from Fraunhofer IIS won Bavaria's regional prize for their idea for the real-time verification of time and positioning data using the encrypted Galileo PRS (Public Regulated Service) navigation service. The concept is to be realized using a simple receiver unit connected to a smartphone, which will make it possible to prove, for example, where and when a photo was taken with the phone.
This idea was the cornerstone for the further development of the PRSauth technology.
