Locating Graves with GPS

Global Positioning System (GPS)

A GPS receiver on the ground, tracking the position of the satellites, can determine its own position (latitude, longitude, and altitude) within 3 metres

Recording a Location

1. Go to the location you wish to record
2. Turn on GPS Receiver
3. Wait for it to acquire the satellites signals
4. Read your current position (latitude, longitude, and altitude) from the screen
5. Record your position in a notebook or in the GPS itself

Returning to a Location

1. Enter latitude and longitude into the GPS Receiver
2. Receiver will show direction and distance to point

Using published Lat/Long to find a Location

1. Make sure the Lat/Long is in the correct format for your GPS Receiver (Ordnance Survey's coordinate transformer is useful)
2. Enter latitude and longitude into the GPS Receiver
2. Receiver will show direction and distance to point

GPS Lat/Long format

GPS Lat/Long format is most commonly displayed as (DDD,MM.MMMM) in which seconds are converted to decimal minutes, as a minute value.
