A LABORATORY SYSTEM FOR THE INVESTIGATION OF RAIN FADE COMPENSATION TECHNIQUES FOR Ka-BAND SATELLITES
The design and performance of a rain fade simulation! counteraction system on a laboratory simulated 30/20 GHz, time division multiple access (IDMA) satellite communications testbed is evaluated. Severe rain attenuation of electromagnetic radiation at 30/20 GHz occurs due to the carrier wavelength approaching the water droplet size. Rain in the downlink path lowers the signal power present at t...
متن کاملSpectral Analysis of Experimental Ka-Band Propagation Measurements over the Australian LEO Microsatellite 'FedSat'
The increased interest in the use of Ka band frequencies in satellite communications has prompted extensive propagation studies and the development of several rain fade models in the past, all of which are based on measurements from geostationary satellites only. Based on novel data, which has been experimentally obtained from the low earth orbit microsatellite ‘FedSat’, this paper addresses th...
متن کاملSpecial Effects: Antenna Wetting, Short Distance Diversity and Depolarization
The Advanced Communication Technology Satellite (ACTS) communications system operates in the Ka frequency band. ACTS uses multiple, hopping, narrow beams and very small aperture terminal (VSAT) technology to establish a system availability of 99.5% for bit-error-rates of 5x 10 or better over the continental United States. In order maintain this minimum system availability in all US rain zones, ...
متن کاملKa-Band Propagation Measurements: An Opportunity with the Advanced Communications Technology Satellite (ACTS)
The Advanced Communications Technology Satellite (ACTS) was conceived at the National Aeronautics and Space Administration (NASA) as a follow-on program to its long history in satellite communications projects that have reduced the risk of developing new technologies that fall outside the sponsorship capability of the private sector. To counter the foreign challenge that developed in the late 1...
متن کاملA Prototype Adaptive Fade Countermeasure System for TDMA Operation at Ka Band
Ka band, the 20/30 GHz frequency band for satellite communications, has gained much interest in recent times. It is well suited for applications with small sized earth stations. The major disadvantage of Ka band, however, is its sensitivity to rain fading. Several satellite experiments are being carried out at the moment studying so called adaptive fade countermeasures, the purpose of which is ...
