ELT to GPS Interface Information
For details on the installation and use of the ELT Computer Test Set TS-451, please
contact Ameri-King Corporation to request the brochures and Operation Manual for
the ELT Computer Test Set.
When used with ELT's that are programmed for Standard Location 24 bit protocol,
the ELT to be program itself to the aircraft's 24 bit address. This feature will allow the
ELT to be transferred between aircraft. This makes maintenance of the ELT a simple
matter of replacing the ELT. Note: There is no electronic connection between TCAS
or Mode S systems and the ELT, only the ID number is common.
The AK-451 receives position data (longitude and latitude) from the aircraft's on-
board GPS system. The ELT may be programmed with the aircraft's 24 bit address.
When used with ELT's that are programmed for long message 24 bit protocol, which
is set up to match the 24 bit address parity of the Mode S surveillance and
communications system switch block.
Note: There is no electronic connection between TCAS or Mode S systems and the
ELT, only the ID number is common. This feature was implemented in the ELT with
fleet operators in mind. ELT's are programmed with either a serialized or 24 bit
protocol. The ELT transmits position data as part of the 406.025 MHz distress
message.
In the event of a crash, the ELT will transmit the converted position information from
the navigation system, such as the GPS flight management computer, loran, etc.
Geostationary satellites constantly monitor the 406.025 MHz transmissions. The crash
site is instantly known due to the aircraft's navigation system position data
