V1.4.1 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 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: - Annex 10 of the ICAO Convention on International Civil Aviation [1]. - ED 92B [i.2]: "MOPS for an Airborne VDL Mode-2 Transceiver Operating in the frequency range 118-136.975 MHz" (2012), which specifies the airborne transceiver. The present document consists of two parts: - the first part provides functional specifications and test procedures for physical layer and MAC sub-layer; - the second part provides functional specifications and test procedures for link and sub-network access layers
