Please find attached a TI-BASIC plus program done on a TI-84 plus, based on what appears to be a novel way to find a location without a known DR.
The program asks to enter GHA, Declination and Ho for three observations (in that order) and then gives the location. West and South coordinates must have a negative sign.
