Introduction The present document states the technical specifications for ground-based equipment implementing Very High Frequency (VHF) Data Broadcast (VDB) air interface, operating in the VHF band (108,000 MHz to 117,975 MHz) in increments of 25 kHz. NOTE: In ICAO Annex 10, Vol. 1 clause 7.2.3 in attachment D it is stated: ".Until compatibility criteria are developed for GBAS VDB and ILS, VDB cannot be assigned to channels below 112.025 MHz." The present document is part of a set of standards developed by ETSI and is designed to fit in a modular structure to cover all radio and telecommunications terminal equipment within the scope of the R&TTE Directive [i.1]. The modular structure is shown in EG 201 399 [i.3]. 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. SIST EN 303 084 V1.1.1:2013
ETSI ETSI EN 303 084 V1.1.1 (2013-05) 6 1 Scope The present document applies to VDB ground-air digital broadcast using Differential Eight Phase Shift Keying (D8PSK) of Ground-Based Augmentation System GBAS, intended for channel increments of 25 kHz. The VDB system provides data broadcast from ground based to aircraft systems, operating in the VHF band (108,000 MHz to 117,975 MHz). The scope of the present document is limited to ground based stations. The present document is intended to cover the provisions of Directive 1999/5/EC [i.1] (R&TTE Directive), article 3.2, which states that ". radio equipment shall be so constructed that it effectively uses the spectrum allocated to terrestrial/space radio communications and orbital resources so as to avoid harmful interference". In addition to the present document, other ENs that specify technical requirements in respect of essential requirements under other parts of article 3 of the R&TTE Directive [i.1] as well as essential requirements under the Single European Sky Interoperability Regulation [i.2] (as amended) and related implementing rules may apply to equipment within the scope of the present document. The scope of the present document is restricted to the civil use of GBAS with horizontally polarized signals (GBAS/H). 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

1 Scope
The present document applies to VDB ground-air digital broadcast using Differential Eight Phase Shift Keying
(D8PSK) of Ground-Based Augmentation System GBAS, intended for channel increments of 25 kHz. The VDB system
provides data broadcast from ground based to aircraft systems, operating in the VHF band (108,000 MHz to
117,975 MHz). The scope of the present document is limited to ground based stations.
The present document is intended to cover the provisions of Directive 1999/5/EC [i.1] (R&TTE Directive), article 3.2,
which states that ". radio equipment shall be so constructed that it effectively uses the spectrum allocated to
terrestrial/space radio communications and orbital resources so as to avoid harmful interference".
In addition to the present document, other ENs that specify technical requirements in respect of essential requirements
under other parts of article 3 of the R&TTE Directive [i.1] as well as essential requirements under the Single European
Sky Interoperability Regulation [i.2] (as amended) and related implementing rules may apply to equipment within the
scope of the present document.
The scope of the present document is restricted to the civil use of GBAS with horizontally polarized signals (GBAS/H).

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in the R&TTE Directive [i.1] and the
following apply:
adjacent channel power: amount of the modulated RF signal power transmitted outside of the assigned channel
NOTE: Adjacent channel power includes discrete spurious, signal sidebands and noise density (including phase
noise) at the transmitter output.
adjacent channel rejection: receiver's ability to demodulate the desired signal and meet the uncorrected BER
requirement in the presence of an interfering signal in an adjacent channel
NOTE: The ratio (in dB) between the adjacent interfering signal level and the desired signal level necessary to
achieve the specified minimum uncorrected BER, is the Adjacent Channel Rejection (ACR) ratio.
Aeronautical Mobile Route Service (AM(R)S): mobile service between ground based stations and airborne 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: with a nominal data rate of 31 500 bits/s, the VDB symbol rate is expected to be 10 500 symbols/s
environmental profile: range of environmental conditions under which equipment within the scope of the present
document is required to comply with the provisions of the present document

ground based station: aeronautical station equipment, in the Aeronautical Mobile Route Service (AM(R)S), for use
with an external antenna and intended for use at a fixed location
radiated measurements: measurements which involve the measurement of a radiated field
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.
