APPENDIX 1 TO CHAPTER 5. EMERGENCY LOCATOR
TRANSMITTER CODING
(see Chapter 5, 5.3.2)
Note.- A detailed description of beacon coding is 2.3 Protected data field
contained in Specification for COSPAS-SARSAT 406 MHz
Distress Beacons (C/S T.OO1). The following technical spec@ 2.3.1 The protected data field consisting of bits 25
cations are specific to emergency locator transmitters used in through 85 shall be protected by an error correcting code, and
aviation. shall be the portion of the message which shall be unique in
every distress ELT.
1. GENERAL
I. 1 The emergency locator transmitter (ELT) operating
on 406 MHz shall have the capacity to transmit a programmed
digital message which contains information related to the ELT
and/or the aircraft on which it is carried.
1.2 The ELT shall be uniquely coded in accordance with
1.3 below and be registered with the appropriate authority.
1.3 The ELT digital message shall contain either the
transmitter serial number or one of the following information
elements:
2.3.2 A message format flag indicated by bit 25 shall be
set to "I)" to indicate the short message format or set to "1" to
indicate the long format for ELTs capable of providing
location data.
2.3.3 A protocol flag shall be indicated by bit 26 and shall
be set to "I" for user and user location protocols, and "0 for
location protocols.
2.3.4 A country code, which indicates the State where
additional data are available on the aircraft on which the ELT
is carried, shall be contained in bits 27 through 36 which
designate a three-digit decimal country code number expressed
in binary notation.
a) aircraft operating agency designator and a serial number; Note.- Country codes are based on the international
b) 24-bit aircraft address;
Telecommunication Union (ITU) country codes shown in
Table 4 of Part I. Volume I of the ITU List of Call Signs and
c) aircraft nationality and registration marks. Numerical Identities.
1.4 All ELTs shall be designed for operation with the 2.3.5 Bits 37 through 39 (user and user location proto-
COSPAS-SARSAT* system and be type approved. cols) or bits 37 through 40 (location protocols) shall designate
one of the protocols where values "001" and "01 1" or "001 l",
Note.- Transmission characteristics of the ELT signal can "0100, "0101", and "1000" are used for aviation as shown in
be confirmed by making use of the COSPAS-SARSAT Type the examples contained in this Appendix.
