Thanks, that is what I thought too but apparently there is a limit, at least according to the person interviewing me.
I remember there being a limit for INS. Approximately 70 degrees N/S because the INS cant figure out E/W from N/S due to high latitudes. Any idea about that. Cant seem to find the reference anywhere though.
