Welcome to the RFCTF Virtual Foxhunt

Welcome to the RFHS Defcon 30 virtual foxhunt. While it would be great if everyone could join us in the village this year, I totally understand if you can't. To give the folks at home something to do, we're running the virtual foxhunt again. This year there will be two Direction of Arrival (DOA) challenges an one Time Difference of Arrival (TDOA) challenge. With the traditional DOA challenges, use the Line of Bearing (LOB) information provided by the simulated recieves to determine the location of the transmitter(s). You'll also see in the header a link to a page called "Time Difference if Arrival". Your task will be to determine the time difference between 3 receivers and use that information to determine the location of a transmitter. You will have to provide the coordinates within 150 meters. Theoretically you'll be able to get a lot closer, within 30 meters given a sample rate of 10 MS/s.
