Satellite Communications


From direct broadcast satellites (DBS) and earth observation to navigation and government/military systems, satellite communications (SATCOM) requires extreme accuracy and reliability. Performance is essential, and there must be seamless communication to make sure transmissions are uninterrupted, despite challenges posed by the atmosphere and an increasingly crowded spectrum.


Ensure Optimum Performance for SATCOM Systems

The rise in unauthorized carriers, cross-polarization interference and other issues has made Radio Frequency Interference (RFI) an on-going concern for the SATCOM industry. Essential to the quick resolution of RFI is the ability to rapidly detect, characterize and geolocate the source of interference.

There are also natural transmission challenges. Ionospheric scintillation and satellite propagation effects from the troposphere can cause transmission problems. Engineers must understand these atmospheric conditions in order to design components and systems that can overcome them.

Engineers are also developing free-space optical communication (FSO) systems for high data rate, long-range, point-to-point links. FSO has been developed to meet the need for high-speed and tap-proof communication systems for both military and commercial use.

For all these reasons, SATCOM engineers must use test equipment that provides the most accurate stimuli and measurements. Anritsu signal generators, such as the MG3690C and MG37020A, have low phase noise, produce narrow pulses, and high power. The MG3690C also generates independent singlet, doublet, triplet, and quadruplet pulses to emulate multiple signals. The VectorStar premium VNA line offers the broadest coverage in a single instrument (70 kHz to 70 GHz), as well as high accuracy and stability.

For highly accurate peak and average power measurements, there is the ML249xA series power meter, which has a mainframe video bandwidth of 65 MHz and an effective settable sample resolution of 1ns in a high resolution repetitive sample mode. Rounding out the portfolio for measuring the RF performance of satellite components and systems are the MS2830A and MS269xA series of Signal Analyzers, which offer excellent dynamic range, low displayed average noise level (DANL) as well as high TOI.

Anritsu also has a full line of test solutions for FSO system design. Our optical spectrum analyzers, including the MS9740A, have the sweep time, dynamic range, and resolution necessary for FSO applications. Engineers also rely on our OTDRs, and Access and Network Master systems in these applications.

So, whether it is for commercial navigation systems such as GPS and Galileo, or military systems that aid in operations, accurate signal transmission is critical. With Anritsu solutions, designers of SATCOM systems and users can ensure their devices and systems are working to optimum performance.
