This GPS enables the geographical coordinates of locations related to MSF missions (villages, refugee camps, boreholes, health facilities, etc.) to be collected and transmitted to headquarters to be incorporated into maps.

The barometric altimeter determines the altitude by tracking changes in pressure. It can be used to plot barometric or ambient pressure over time in order to keep an eye on changing weather conditions.

The official software for the device, MapSource, is sold separately. Other software may also be used (OziExplorer, etc.). Ensure that you have a valid licence.

If this GPS is to be used in a vehicle, an external antenna should be ordered (see "Related Articles" below).

Warnings

• GPS equipment is prohibited in some countries and is often regarded as espionage equipment.
• A GPS does not take the place of a compass or a clinometer.
• The accuracy of the coordinates depends on the number of satellites the GPS can "see" (at least 3 for longitude/ latitude and at least 4 for longitude/latitude/altitude).
• The GPS satellites are operated by the US Department of Defense. Transmissions may be jammed or discontinued in some "contexts" (such as wartime).
• Mapmaking is a profession. The use of GPS by MSF missions should be limited to the recording of geographical coordinates as described above.
