Open source GPS signal generation would be quite valuable to the information security community. See for example this nice paper that shows how a GPS simulator can be used to explore the wireless attack surface of GPS receivers:
http://users.ece.cmu.edu/~dbrumley/courses/18487-f12/readings/Nov28_GPS.pdf I'm not up to date enough on the existing GNSS receiver projects to know how valuable #2 would be to the community.
