A LES-5 Beacon Receiver
نویسندگان
چکیده
A functional description of a communications satellite beacon receiver is presented. The system, designed primarily for LES-5/6, is capable of reliable unattended operation, and provides a frequency and time reference for fixed and highly mobile satellite communications terminals. Theoretical and experimental data are given, with particular emphasis on automatic acquisition and tracking of the satellite beacon signal at low signal-to-noise-density ratios under adverse channel conditions.

متن کاملA Ka-band Satellite Beacon Receiver for Propagation Experiment
The design of a low-cost beacon receiver based on software defined radio is presented. The motivation for such a receiver is to investigate atmospheric impairments at the Ka frequency band. The receiver has been tested by the Hotbird 13A, ASTRA 3B and Alphasat satellite beacon signals. A GNU Radio software development toolkit and a USRP device were used for the development of a beacon receiver ...
متن کاملEasy-to-Build Satellite Beacon Receiver for Propagation Experimentation at Millimeter Bands
This paper describes the design and development of a digital satellite beacon receiver for propagation experimentation. Satellite beacons are frequently available for pointing large antennas, but such signals can be used for measuring rain attenuation and other phenomena as, for example, tropospheric scintillation. A fairly inexpensive beacon receiver has been built using off-the-shelf parts. T...
