HF DATA LINK (HFDL)

HF DATA LINK (HFDL)SP-2310SELEX Elsag supplies the SP 2310 Airborne HFDL systemto provide main airborne platforms with the capability forHF voice and data communications. Together with anACARS management unit or communicationsmanagement unit (CMU) the SP2310 HFDL provides thecapability to exchange data with other aircraft or groundstation supporting AOC, ATS and ATC services.The SP-2310 comprises the following units:• HF transceiver (HF RT) or HF Data Radio (HFDR) SP-2311• Antenna Tuning Unit ATU-2005The HFDR SP-2311 includes an internal modem for datacommunications in accordance with Arinc 635.The ATU-2005 is a digital antenna coupler for shunt/notchantennas in accordance with ARINC 753/719.The transceiver operates on frequencies spaced 100 Hzin 2-30 MHz High Frequency range allowing Single SideBand (SSB) voice, Amplitude Modulated Equivalent(AME), Continuous Wave (CW), Selective Calling(SELCAL) and data functions. The transceiver is form,fit and function compliant with ARINC standard includinginterfaces and connectors. The HF data radio is designedto satisfy interoperability requirements.FEATURESGeneral• Full Digital Architecture• Low Power Consumptions• High Reliability• RTCA-DO/163 Functional Compliance• RTCA-DO/265 Functional Compliance• RTCA-DO/160C Environmental Compliance• RTCA-DO/178B Level C software Compliance• RTCA-DO/254 hardware Compliance• ARINC 615 loadable

• Comprehensive Built-in Test (PBIT, CBIT, IBIT) for faultdetection and isolation• ARINC 600 Form/Fit/Function• Extended frequency range available for military andnon-standard aviation applications• Available in configuration 400 Watt PEPCOMMUNICATION• Single Transmitter / Receiver• ARINC 753 and ARINC 719 compatible• HFDL Mode data mode compliant with relevant ICAO,RTCA & EUROCAE Standards• Interfaces: MU/CMU, OMS, BITE, Cross Link, HFDCFHF DATA RADIO SP-2311The SP-2311 performs Communication voice functionalities(ARINC 753/719 Mode) or data functionalities (ARINC753 and ARINC 635).In a double configuration, two SP-2311 can be linkedtogether (via Cross Link) to automatically provide hotbackup of data functions in case of failure. Thanks tothis connection the two radios are always synchronized(configurations, addresses table, etc) and are able todetect immediately the failure on the other one.OPERATION – COMMUNICATIONThe SP-2311 has three modes of Operations:• Voice (ARINC 753/719 Mode)• Analog Data (ARINC 753 Mode)• Digital Data (HFDL as per ARINC 635)In Voice mode the SP-2311 behaves as a standardAM-SSB Transceiver. Voice signals are provided vianormal audio I/O, with transmit and receive conditionsinitiated by the operator with the microphone.In Analog data mode, the HFDR receives data audioand data key line from analog data unit and sendback received data audio.In Data mode the SP-2311 provides servicesfor Physical, Link and partially Network layersof OSI model.CONTROLThe SP-2311 is designed to be controlled by thefollowing interfaces:• ARINC 429 Standard (High/Low Speed)• Other standard avionics interfaces (upon request)

DISCRETE CONTROLS AND INDICATIONSThe SP-2311 provides the necessary discreteinterfaces with the platform.Indications and relevant discrete regarding theequipment status are also provided.SOFTWAREThe SP-2311 is designed according to flexiblesoftware architecture and with a design developmentin accordance with RTCA DO-178B level C.DESIGN AND CONSTRUCTIONThe SP-2311 is fully digital equipment;it makes extensive use of large-scale programmablecomponents (DSP) and state of art technologies,in order to reduce volume, power consumption andweight, while maximising the reliability.Its structure is modular and includes a powerfulBITE (Power-up, Continuous and Initiated BIT).ATU 2005TECHNICAL SPECIFICATIONSEnvironmental conditionsOperating temperatureGround Survival TemperatureAltitudeFrequency RangeFrequency StabilityRTCA DO-160D- 40°C to +70°C- 55°C to +85°C-15000 to 50000 feet2 to 30 MHz± 20 HzOutput PowerAME: 50 W average, nominal +1.0 dB, -1.5 dB; CW: 50 W;SSB:400 W PEP, 125 W average, nominal +1.0 dB, -1.5 dB; AME: 125 W average, nominal +1.0 dB, -1.5 dB;CW: 125 W;LoadData Link Rates50 ohm300, 600, 1200, 1800 bit/sRX SelectivitySSB passband variation:2 dB for fc +350 Hz to fc +2500 Hz;35 dB, from fc to fc -300 Hz and from fc +2900 Hz to fc +3300 Hz;60 dB, for frequencies less than fc -300 Hz and greater than fc+3300 HzRX SensitivitySSB:AM:RX Dynamic RangeCoolingDimensions1 µV for 10 dB (s+n)/n4 µV for 10 dB (s+n)/n (30%mod@1KHz))-98 to –7 dBmARINC 600 with cooling airARINC 600, 6 MCU for HFDR;ARINC 600, 6 MCU for ATU @ 400 watt PEP configuration;Weight SP-2310 @400 Wless than 19 KgLRU Connector ARINC 600, size 2Power SupplySoftware Developments115 VAC, 400 Hz, 3 phaseRTCA/DO-178B Level C
