How accurate is "very accurately"? How quickly do you need the answer? I was thinking of a sundial. Normally, you know which way is north and they tell you time. If you know the time, you can point them north. Neville suggested stars. They don't work during the day, but amateur astronomers are pretty good at this problem. Can you go up some night ahead of time and survey a line between a pair of (semi-)permanent markers? Neither of those ideas work if there is too much cloud cover. I'm guessing you want to point an antenna at a (very?) weak signal. Can you calibrate things by pointing at some signal at a known direction that is strong enough so you can easily find it and tune for a max? -- These are my opinions, not necessarily my employer's.
