LOPs from celestial heights?



Yes you are correct Nav,

The St Hiliare method Is the establishing of a line of position from
the observation of the altitude of a celestial body by the use of an
altitude difference and azimuth.

St Hilaire came up with this method crossing the desert with
Nepolian.


I didn't know that -I though he must be a patron saint of navigators...

Cheers
