INTRODUCTION
This manual provides description, installation, operation, and maintenance information for
the ME-183 NAV Interface (ME-183 NAV). The ME-183 NAV relays latitude and longitude
position data to the ELT for incorporation into the 406 MHz Search and Rescue (SAR)
satellite message. The ME-183 NAV is designed as a retrofit accessory for Artex ME406
Series ELT installations.

System Advantages
An ME406 ELT system, with the ME-183 NAV interface retrofit kit installed, contains a
number of significant advantages over older technology ELT systems:
•
Greater Position Accuracy (Figure 1-1)
•
Position Data from a Single Beacon Transmission
•
No Aircraft Power (power derived from GPS data output)
