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.

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.

BD406

DV 16401.03 Issue 3 2/2013 Page 2-33

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.

2.6 Troubleshooting Problem Possible Reason Proposed Solution No active backlight. Wrong Dimming Input is chosen in

Installation Setup. Set appropriate input and dimming voltage for particular installation.

Dimming Input set to NONE in Installation Setup and Brightness set to 0.

Adjust Brightness.

BD406

Page 2-34 DV 16401.03 Issue 3 2/2013

In Installation Setup CH CTRL CONFIG option is unintentionally set to LISTENER.

Set CH CTRL CONFIG option to FULL.

The display shows warning or error.

Refer to section 3.1.6. Refer to section 3.1.6

Device does not receive beacons transmission.

Invalid antenna installation. Check antenna installation.

Unknown source of interference. Refer to 2.5.6 Interference Check.

2.7 Continued Airworthiness Maintenance of the BD406-(XX1)/PBD406-(XX1) is “on condition” only. No maintenance of this product is required. It is recommended to check the frequency accuracy of the local frequency reference after 10 years; refer to Maintenance and Repair BD406/PBD406-(XX1) document for details (section 1.8).

2.8 Targets Status Protocol - IF3 Interface

2.8.1 Scope

This specification describes the broadcasting protocol available on the IF3 interface of the BD406 device. The protocol is used for reporting status information about all Targets stored in BD406 device. It utilizes unidirectional broadcasting transmission compliant with RS232. Only outgoing transmission from the BD406 IF3 interface is available (BD406 is a Transmitter). It is recommended that device which receives these packets (Receiver) should meet requirements from section 2.8.5.

2.8.2 Terms’ Definition

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.

Page 2-42 DV 16401.03 Issue 3 2/2013

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).

Homing message is triggered by pressing Rotary Knob or by activating GPI_0 (section 2.3.3.8).

3.1.6 Warning and Failure Indications BD406-(XX1) / PBD406-(XX1) is able to provide the user additional information about existing or occurred malfunctions. Not all abnormal situations can be presented to the user but the device will try to show scope of error. The device tests itself during test called PBIT. The test is performed during each power-on process. The receiver shows error screen with information about total number of errors that were registered in the system, number of current error, error identifier (Error ID), short description, user action – if available. There are errors that cannot be removed from the screen. If this kind of malfunction occurs – immediately contact service. Action, related to errors that can be confirmed by the user, is dependent on particular malfunction. Table 3-4 below defines scope of malfunction.

Course Deviation Indicator visible in Beacon / NavPoint detailed view Menu shows angular difference between two courses:

• Defined between coordinates of Fixed Position and coordinates of the Target (Beacon or NavPoint).

• Current coordinates of the device and coordinates of the Target. CDI belongs to range [-90, 90] deg. Details are shown on Figure 3-8. Indications are not related to the device’s velocity – only position is taken into account. CDI shows valid values only if Target and GPS source provide valid data. If CDI value is valid – a value of deviation can be calculated in distance units (kilometers or nautical miles). Details are shown on Figure 3-9.

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.

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:

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 01/01NEW BEACON

DETECTED

Press STOto 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


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:
