Thales Alenia Space is in charge for the development, integration and production of the whole Global Star II satellite constellation. To support the production of the RX L-Band Active Antennas, a new Spherical Near test facility was developed and installed at Thales Alenia Space Italy premises. This paper gives an inter-comparison of the measurement results obtained among three facilities that are a Test Range installed at TAS-France, a Spherical Near-Field already available at TAS-Italy and the new SNF facility. The test comparison has been considered as a part the new SNF facility validation. In particular the comparisons of copolar and crosspolar patterns, peak directivity and general Antenna performances are shown...
