Development of Specifications for an L-DACS1 System

ICAO/AP17 and SESAR proposed follow-on activities for further characterizing the proposed L-DACS options, validate their performance, and lead to a single technology recommendation for the L-band. They have both recommended to complete the L-band data link investigations (with emphasis in proving the spectrum compatibility with other systems) aiming at a final decision by 2009/2010, to enable system availability for operational use by 2020. - Complete the investigation of compatibility of prototyped L-DACS components with existing systems in the L-band particularly with regard to the onboard co-site interference and agree on the overall design characteristics; - Evaluate and validate the performance of the proposed solution in the relevant environments through trials and test bed development; - Propose the appropriate L-DACS solution for input to a global aeronautical standardisation activity, considering the design trade-offs.
