This paper presents the results of in-depth validation of a DVB-S2 system with ACM, using a laboratory demonstrator developed under a European Space Agency Artes 5 contract “ACM Modem”. The reference scenario used to define the test cases consists of a multi-beam Ka-band satellite system, representative of future systems to provide broadband access by satellite at a low cost and with high service availability, made possible with the DVB-S2 standard. The demonstration platform is based on a commercial gateway and terminal, which modulator and demodulator have been adapted to include DVB-S2 and ACM functionalities and detailed test points, a two-way satellite channel emulator, IP traffic generators and analysers and a control & monitoring station for test automation.
