Just be aware that, if the GS and LOC are not protected, you can have a wild ride. I was an engineering observer for hundreds of flight test autolands and, since all were done in VMC, there was no protection. Things got quite exciting low on one approach when a grass mower passed in front of the LOC antenna.
On another flight test program a Douglas trijet nearly took out runway signage because the crew didn't understand the implication of an unprotected ILS. A very late GA saved the sign (and perhaps the aircraft).
