Introduction The present document states the technical specifications for ground-based equipment implementing Very High Frequency (VHF) Digital Link (VDL) Mode 2 air interface, operating in the VHF band (117,975 MHz - 137,000 MHz) with 25 kHz channel spacing. Manufacturers should note that in the future, all or part of the frequency band 108,000 MHz to 117,975 MHz may become available for aeronautical communications. The present document may be used to produce tests for the assessment of the performance of the equipment. The performance of the equipment submitted for type testing should be representative of the performance of the corresponding production model. The present document has been written on the assumption that: - the type test measurements will be performed only once, in an accredited test laboratory, and the measurements accepted by the various authorities in order to grant type approval; - if equipment available on the market is required to be checked it may be tested in accordance with the methods of measurement specified in the present document.

ETSI ETSI EN 301 841-1 V1.1.1 (2002-01) 7 1 Scope The present document applies to VDL Mode 2 ground-air digital communications using Differential Eight Phase Shift Keying (D8PSK), intended for channel increments of 25 kHz. The VDL Mode 2 system provides data communication exchanges between aircraft and ground-based systems. The scope of the present document is limited to ground-based stations. The VDL Mode 2 system is designed to be a Ground/Air sub-system of the Aeronautical Telecommunication Network (ATN) using the AM(R)S band and it is organized according to the Open Systems Interconnection (OSI) model (defined by ISO). It shall provide reliable subnetwork services to the ATN system. The present document provides functional specifications for ground-based radio equipment intended to be used for ground-air data communications. The present document is derived from the following documents:
• VDL Mode 2 SARPs version 3.0. ICAO Annex 10 Volume III part I [1]. • ED 92 [2], Minimum Operational Performance Specification For An Airborne VDL Mode 2 Transceiver Operating In The Frequency Range (118,000 MHz -136,975 MHz) Physical Layer, March 2000, which specifies the airborne transceiver. The present document consists of two parts: • the first part provides functional specifications and test procedures for physical layer; • the second part provides functional specifications and test procedures for link and sub-network access layers. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. • References are either specific (identified by date of publication and/or edition number or version number) or non-specific. • For a specific reference, subsequent revisions do not apply. • For a non-specific reference, the latest version applies.

ETSI ETSI EN 301 841-1 V1.1.1 (2002-01) 9 aeronautical mobile service: mobile service between aeronautical stations and aircraft stations, or between aircraft stations, in which survival craft stations may participate average transmitter output power: average power supplied to the antenna transmission line by a transmitter during an interval of time sufficiently long, compared with the lowest frequency encountered in the modulation, taken under normal operating conditions Bit Error Rate (BER): ratio between the number of erroneous bits received and the total number of bits received NOTE: The uncorrected BER represents the BER without the benefit of Forward Error Correction (FEC). Co-Channel Interference (CCI): capability of a receiver to demodulate the desired signal and achieve the minimum specified BER performance in the presence of an unwanted signal at the same assigned channel NOTE: The ratio (in dB) between the wanted signal level and the unwanted signal level is the co-channel interference ratio. conducted measurements: measurements which are made using a direct rf connection to the equipment under test data rate: VDL Mode 2 symbol rate shall be 10 500 symbols/s, with a nominal data rate of 31 500 bits/s ground base station: aeronautical station equipment, in the aeronautical mobile service, for use with an external antenna and intended for use at a fixed location interleaver: creates the AVPL_TIRS sequence made from the block segmentation of the AVLC frame and the RS encoding NOTE: To this end one assumes the TIRS matrix made from the RS encoding of the AVLC block segmentation. The TIRS matrix is a matrix of octets made of 255 columns and c rows. spurious emissions: conducted rf emissions on a frequency or frequencies which are outside the necessary bandwidth and the level of which may be reduced without affecting the corresponding transmission of information NOTE: Spurious emissions include parasitic emissions, intermodulation products and frequency conversion products.
