1.2 Purpose of Equipment
BD406-(XX1) / PBD406-(XX1) COSPAS/SARSAT Beacon Decoder is designed for use by
SAR authorities as a tool to provide vital information and assistance during rescue
missions. Usage of BD406 in SAR missions reduces the time required to locate a distress
signal, which has a direct impact on the probability of survival of the person in distress at
sea or on land.
The BD406 decoder/receiver provides immediate and direct detection of the distress
messages transmitted on 406 MHz (ELTs for aviation use, EPIRBs for maritime use, and
PLBs for personal use). It decodes the position of the transmitted signal, displays the
beacons relative position and allows continuous tracking during the rescue mission.
The International Satellite System for Search and Rescue (COSPAS-SARSAT) system is
described on www.cospas-sarsat.org.

1.4.4
PBD406-(XX1) Power Supply
PBD406-(XX1) power is supplied from an internal 12.0 V maintenance-free rechargeable,
sealed dry acid battery. The internal power module, installed inside the chassis, is capable
of operation within a 9 – 36 V DC range.
Estimated charge time for a depleted battery is approximately 8 hours. The charger
(Figure 1-3) can also be used as an external power supply; therefore there is no need to
disconnect the charger when the battery is fully charged. The charger can be safely left
plugged in. The nominal operating time on full battery charge is no less than 5 hours.
The battery is protected against a deep discharge – PBD406-(XX1) will not operate / start
when battery voltage is lower than 10.5V.
The battery should be charged every six months for long term inactive storage periods of
more than six months.
Note: Operating time of PBD406-(XX1) may decrease for ambient temperatures
below 0 °C.

2.2 Mechanical Installation
2.2.1 BD406-(XX1)
BD406-(XX1) is to be fitted at a suitable place on the aircraft. The mounting place shall be
at least 30 cm from the magnetic aircraft compass, to avoid any interference to the
magnetic compass by the device. It is constructed for mounting from behind the panel by
means of four screws, which are included in the delivery. The circular cutout and the
mounting holes are to be drilled in accordance with the instrument size. For typical
installations, there is no need for external cooling of BD406-(XX1). Leave a clearance of
minimum 5 mm between the BD406-(XX1) and other avionics to allow air circulation. The
necessary dimensions for the installation are given in Figure 2-1, Figure 2-2, Figure 2-3.

The speaker output provides a nominal 4 Watts into 4 Ohms load. For the best
performance use a pair of shielded wires (AWG20) and trace a signal path as short as
possible. It is recommended to mount the speaker and wires’ shield isolated from an
aircraft frame in order to avoid ground loops. Pin 14 SPKR- is internally connected to the
GND potential.
CAUTION: The magnetic field of a speaker may influence the magnetic compass.
When choosing the speaker mounting point, determine a distance that

2.3.4 Installation Wiring
Connection to the following equipment is required as minimum for BD406-(XX1)/
PBD406-(XX1):
• Power Supply
• Antenna RF
• GPS antenna or external GPS source (to achieve the full performance of the
device)
Note:
Use only a cable which is fit for aircraft use (self extinguishing): AWG20 for power
supply, AWG16 for grounding bolt, for other cables refer to: Figure 2-14, Figure
2-15, Table 2-1, Table 2-2.
Fit sleeves over the solder joints on the equipment connector.
Protect the power supply with a 2.5 A fuse or circuit breaker.
No high frequency cables should be included in the cable harnesses of the system.
The routing of connecting cables alongside cables which carry audio power or
pulses (DME, XPR) should also be avoided.
Check the wiring carefully before switching on the unit and check particularly that
power supply lines have not been reversed.
Typical installation wiring diagrams are shown on Figure 2-14, Figure 2-15.

2.3.5 Installing the antennas
The BD406-(XX1) / PBD406-(XX1) require a standard 50 Ohm vertically polarized UHF
antenna for dedicated band.
An active GPS antenna is needed to utilize full functionality of the device. Follow the
antenna manufacturer's installation instructions for mounting them in an aircraft.
CAUTION: Active GPS antenna should only be connected to the BD406-(XX1) /
PBD406-(XX1) receiver when the receiver is not powered. Do not connect
or disconnect the GPS antenna when the PBD406-(XX1) is running as the
internal GPS receiver calibrates the noise floor on power-up. Connecting
the antenna after power-up can result in prolonged acquisition time.

2.5 Post Installation Tests
It is assumed that the Installation Setup (section 2.4) has been performed before the Post
Installation Tests. Once the unit is installed, complete a post installation check to verify
proper system operation. After installing the unit it is necessary to establish whether any
equipment in the aircraft electrical system is generating interference. Guidance for such
tests is provided in sections below.
2.5.1 Mechanical Installation and Wiring Check
Verify that all cables are properly secured and shields are connected to signal ground.
Check the movement of aircraft controls to verify that there is no interference. Verify that
all screws used to fastening the BD406-(XX1) in the installation cutout are tight and the
connectors on the rear side of the unit are secured.
2.5.2 Power Supply
Check the power supply lines for correct polarity. Check that the aircraft power supply is
within the specified limits with and without a running engine(s).
2.5.3 Activated Installation Options
Check all subsystems of BD406-(XX1) that were activated during Installation Setup: audio
systems, transmission interfaces, etc.
2.5.4 Receiver Reception Check
Verify proper reception of COSPAS/SARSAT signal. It is recommended to use dedicated
BT406 Test Setup to generate test signal in full allowable range. Minimal reasonable test
should utilize a PLB set in Self Test mode. Refer to Operation’s Manual of the particular
PLB.
Page 2-32
DV 16401.03 Issue 3 2/2013
BD406
CAUTION:
It is absolutely mandatory to follow all regulations regarding generation of RF
COSPAS/SARSAT distress signals.
If a PLB is used as a source of a test signal, it is strictly forbidden to activate it in
live emergency mode - each emergency call instantly triggers a search and rescue
operation. Misuse is strenuously prosecuted and can incur claims for damages.
Unauthorized persons may not operate the PLB.
2.5.5 Antenna Check
Refer to antenna’s manual for details on installation.
2.5.6 Interference Check
With the engine(s) running and the aircraft electrical system on, check whether radio
beacons at boundary range can still be received without interference.
Check also that the BD406-(XX1) does not cause significant interference with other
systems.
Check the interference of VHF-COM equipment to the GPS system used by BD406(XX1).
Should the reception be influenced by local interference, trace the source by
systematically switching off the electronic equipment, generators, etc. on the aircraft to
establish which component is causing interference. Then suppress interference
accordingly.
Typical sources of interference are: generators, regulators, static inverters, choppers, DC
converters, RF sources: transponders, DME, communication equipment.
2.5.7 Flight Test Check
A flight test is recommended for final installation verification. The performance may be
verified by reception of a distress beacon at a range of at least 25 NM while maintaining
an appropriate altitude and over all normal flight attitudes. Performance should be
checked with usage of all required navigation and communication equipment installed on
the aircraft and used during simulated rescue mission.

2.8.4.3 Packet Broadcasting
The Transmitter broadcasts status of all existing Beacons (Frame ID 0x00)
consecutively and then broadcasts status of all existing NavPoints (Frame ID 0x01)
consecutively. The Transmitter repeats this process continuously. The more Beacons
and NavPoint in databases the more data are transmitted. When neither Beacons nor
NavPoints are present in memory - empty frames with Byte 1 equal 0 appears.

2.8.4.4 Packet CRC Definition
Packet CRC shall be calculated using 16-bit binary polynomial represented by number
0x8005 (known as CRC-16). Packet CRC shall be calculated from sequence of bits
consisting of Packet Header, Protocol ID, Frame Length and Frame. Bits shall be
inserted for Packet CRC calculation starting from the MSb of the Packet Header.
Examples of calculated checksums:
Input: 0x0000 Result: 0x0000
Input: 0x0001 Result: 0x8005
Input: 0x0001 0x8005 Result: 0x0000
Input: 0xFFFF Result: 0x800D
Input: 0xA514 0x0120 Result: 0x43E3
2.8.4.5 Maximal Duration of the Transmitted Packet
Duration of outgoing Packet is no longer than twice the minimum time required for
Packet transmission:
[Max Packet duration] <= 20 * [1/bit rate] * [number of bytes in the Packet]
2.8.5 Recommended Receiver Operation
2.8.5.1 Incoming Packet
The Receiver shall scan for the Packet Header, capture the Packet and verify the
Packet CRC. Packets with incorrect CRC shall be rejected.
Device which receives valid Packet shall assume that Frame is Valid if:
 Frame ID is correct for Protocol ID extracted from Packet,
 AND the length of the received Frame is correct.
Otherwise the Frame is assumed to be Invalid. Invalid Frames should be ignored.
2.8.5.2 Length of the Longest Supported Packet
The Receiver shall be able to properly work with Packets which length is not greater than
75 bytes.

3.1.2 PBD406-(XX1) Controls
Portable version of Beacon decoder has the same set of controls. Additionally push-button
B1 (refer to section 2.3.2) is present in front panel of the housing. When it is pressed
screen backlight is activated for around 15 seconds.
3.1.3 PBD406-(XX1) Usage Recommendations
PBD406-(XX1) is equipped with dedicated GPS antenna which shall be attached directly
to the SMA socket J5 (refer to 1.7.2 section for its type).
The portable UHF 406MHz antenna has a hook that may be used to attach the antenna to
any object that extends PBD406 reception range during a rescue mission (a mast, etc.).
The antenna can be also held in a hand (near BNC connector) however it can limit an
effective range of a signal reception.
CAUTION: Active GPS antenna should only be connected to the PBD406-(XX1)
receiver when the receiver is not powered. Do not connect or disconnect
the GPS antenna when the PBD406-(XX1) is running as the internal GPS
receiver calibrates the noise floor on power-up. Connecting the antenna
after power-up can result in prolonged acquisition time.
The GPS antenna shall have direct visibility of the sky to maximize its effectiveness. It
shall not be covered by any objects, as it degrades quality and reliability of the fixed
position.
Any obstructions in the area of the GPS antenna can cause a very significant reduction in
accuracy. Examples of interfering obstructions include: buildings, trees, fences, cables
etc. Obstructions may have the following effects thereby reducing accuracy: reduced
number of satellites seen by the receiver, reduced strength of satellite geometry (high
PDOP values).

3.2.7 Receive Operation – Message Detection
BD406-(XX1) / PBD406-(XX1) is a digital receiver of COSPAS/SARSAT compliant RF
signal. With its exceptional sensitivity the beacon decoder provides reliable reception and
validation of any rescue radio beacon. It works in a range of 406.020 – 406.081 MHz. The
receiver continuously scans the rescue band and detects beacons’ transmissions. When
beacon’s RF signal is detected its full analysis is performed to check signal’s amplitude,
quality (phase and time parameters), and frequency.
DV 16401.03 Issue 3 2/2013
Page 3-33
BD406
Advanced correction algorithms improve reception ability and provide a wider range in
variable environmental conditions. Even if the received signal is distorted due to beacon’s
malfunction, an excessive distance, or harsh weather conditions, additional actions are
performed to validate and correct such datagram.
Temperature Compensated VCO guarantees maintenance free, long term stability
≤ +/- 5ppm after 10 years at temperature range -40 °C to 85 °C (for BD406-(XX1)).
Usually, when rescue mission is started Beacons database is empty. When device is
powered on the following screen appears:
B --/--
1/6
PT: ----BT: ----CNTR: ---
SN: ----TAC: ----
When rescue signal is received - BD406 analyses captured data stream (consisting 112 or
144 bits) and automatically stores decoded data into the first free record of internal
Beacons DB. Voice notification is generated: ‘New Beacon’ and repeated every 6
seconds; in meanwhile a warning message appears on the screen:
WARNING 01/01
NEW BEACON
DETECTED
Press STO
to confirm
The warning screen and audio notifications are active until user confirms action by
pressing STO key. Once warning screen is confirmed Beacon Detailed view appears with
decoded information about the recently received message:
B 01/01
1/6
PT: STD-LOC
BT: EPIRB
CNTR: 279
SN: 14000
TAC: 0719
When next message from the same beacon is received audio notification: ‘Beacon’ is
audible and ANT symbol appears on the screen for 0.5 second (refer to Table 3-2).
When new message is received outputs /MSG and /GPO_0 are activated for 400ms.
When message from registered beacon is received again only /MSG is activated for
400ms.
The device can store up to 49 different beacons. When the following conditions are met:
Beacon DB is full and a received message does not exist in Beacon DB two kind of
warning may appear:
If in Installation menu on FULL DB CONF screen STORE NEW BEACON is highlighted
warning WARN-01 appears:
