Smith Myers have designed application specific cellular systems for over 30 years. This expertise has produced Artemis, a location and communication system for SAR aircraft. Artemis finds a person by using their phone as a location beacon. The system does not require a local Cellular network, and is therefore ideal for disaster situations and or remote locations. It can also be employed in border protection missions. No specialist DF antenna array is required, and the user interface is via a web browser running on any screen with a LAN connection. Artemis is qualified to DO160G and MilStd810G EMC and environmental for fixed and rotary wing aircraft.
