Holkirk Digital IF EDGE TERMINALS: Revolutionising Satellite Communication

Introduction

Holkirk Communications continues to lead the way in satellite communication technology with their cutting-edge Digital Intermediate Frequency (DIF) EDGE TERMINALS. These terminals are designed to seamlessly integrate traditional RF technology with modern IP-based networks, providing unparalleled flexibility and efficiency in signal distribution.

Working with our partners ETL Systems to ensure DiFi interoperability with the Genus Digital 5000 we will deliver DIF EDGE terminals that will provide efficient signal sampling, seamless IP encapsulation, accurate reconstruction and maintain digital integrity

What is DIF?

To understand the significance of Holkirk’s DIF EDGE TERMINALS, it’s essential to grasp the concept of Digital Intermediate Frequency (DIF).
Intermediate Frequencies (IF) have been a cornerstone of RF systems since 1918. They are used to distribute signals around ground stations by down converting the RF signal to an intermediate frequency before passing it to a demodulator for further processing.

Conversely, the output of the modulator is distributed at IF to the appropriate antenna for up-conversion, prior to transmission to the satellite.
Digital Intermediate Frequency (DIF), also known as RF over IP, performs the same function but with a modern twist. It links traditional RF technology with the evolving cloud-virtualized ground segment, distributing RF signals over IP (Internet Protocol).

This requires access to an IP network with 100GbE Ethernet capability. Think of it like the transition from analogue broadcast to digital – today, consumers enjoy more choice and better picture and sound quality because of the standardization and efficiencies that digital brings.

Acquiring Inclined Orbit Satellites

Our AIM control unit is engineered to track non-geostationary (non-GEO) satellites, including those in inclined orbits. These inclined orbit satellites can present challenges due to their unique movement patterns, but the AIM control unit is equipped with sophisticated functionalities to address these challenges.

Toast rack Search Method

One of the key features of the AIM control unit is its ability to perform a toast rack search. This method utilises the beamwidth of the satellite, the inclination angle, and the estimated position (box centre) of where the satellite should be. By carefully calculating these parameters, the AIM control unit systematically scans the sky, ensuring that the antenna is accurately aligned with the satellite’s position. This process optimises the acquisition and tracking of inclined orbit satellites, providing reliable communication links.
