Recent Ka-Band Weather Statistics for Goldstone and Madrid
نویسندگان
چکیده
Ka-band (32-GHz) radio communication links are more adversely affected by atmospheric noise temperature than X-band (8.4-GHz) or S-band (2.9-GHz) links. As a result, the strategy for telecommunications between a spacecraft employing Ka-band and the Deep Space Network is necessarily different from that employed at the lower frequencies. To aid in the development of new communication strategies, several years of 31.4-GHz water vapor radiometer data from the Goldstone and Madrid sites were reduced. Renewal theory was employed to examine the failure and recovery statistics of these Ka-band weather-dependent links.

Optimization of a Deep-Space Ka-Band Link Using Atmospheric-Noise-Temperature Statistics
Statistics for atmospheric-noise-temperature data at a 31.4-GHz frequency were calculated for the Madrid and Goldstone Deep Space Communications Complexes from the data collected by the water vapor radiometer. These data consist of 74 months of measurements at Madrid and 46 months of measurements at Goldstone. The statistics then were used to optimize a deep-space 32-GHz (Ka-band) link at each ...

متن کاملTypical Ka band Satellite Beacon Receiver Design for Propagation Experimentation
This paper presents the design and simulation of a typical Ka band satellite beacon receiver for propagation experimentation. Using satellite beacon signal as a reference signal in satellite wave propagation study, is one of the most important methods. Satellite beacons are frequently available for pointing large antennas, but such signals can be used for measuring the effect of natural phenome...
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 کاملKa-band link optimization with rate adaptation for Mars and lunar communications
On-going development of Ka-band capability for the Deep Space Networks (DSN) will radically increase the bandwidth available to support advanced mission concepts envisioned for future robotic as well as human exploration of Mars and beyond. While Ka-band links can operate at much higher data rate than X-band, they are much more susceptible to fluctuating weather conditions and manifest a signif...
