Satellite Interference & Monitoring Companies

Crystal is a software control systems company that designs and delivers network monitoring and management solutions to improve operational efficiency, analyze errors, and enhance system resiliency. The company offers two products in the satellite interference sphere.


Crystal Spectrum Monitoring and Recording (SMR) is a spectrum monitoring and recording system designed for the satellite industry. With it, dozens of satellite carriers can be monitored, and snapshots of spectrum segments can be taken to retune the analyzer, allowing users to utilize their existing equipment to monitor many different carriers. Acceptable limits can be applied to customer systems, and in the case of an interference event, Crystal SMR can record the data to enable analysis after the event. Users are notified of interference events via text message, email, on-screen message, etc.


The second interference solution is the Crystal Carrier ID detection system. With an off-the-shelf Carrier ID detector from Comtech EF Data or TeamCast, the system looks at specific frequencies and extracts the Carrier ID, enabling users to confirm that the ID they expect at a certain frequency is really there. As the use of Carrier ID becomes increasingly widespread and required by more and more governments around the world, systems like the Crystal Carrier ID provide satellite broadcasters with a validation tool for their own Carrier ID.

Glowlink offers a range of products aimed at improving satellite communications and mitigating interferences, spanning carrier and spectrum monitoring and interference detection and geolocation, among others.


In addition to its standard, wideband and ultra-wideband DSP spectrum monitoring solutions, Glowlink offers the GS380S Signal Separation System, which separates two signals that overlap in the same frequency using only minimal information about the primary carrier, an ideal solution for solving major interference. The GS308X Interference Removal System, meanwhile, effectively removes all noise and interference regardless of type (hopping, burst, modulated, unmodulated, etc.), again armed with just minimal information about the primary carrier.


Glowlink also has three products in its geolocation suite. The Model 8000 Integrated Geolocation and Spectrum Monitoring System is, according to Glowlink, the only product on the market with the entire system (acquisition hardware and processing software) integrated on a single, rack-mountable chassis. It is successful even with challenging satellite configurations, such as distant adjacent satellites (e.g. 20 degrees), satellites in highly-inclined orbits, and satellites with very little motion.


Glowlink also offers a proprietary single satellite geolocation (SSG) product, which is currently in its fourth generation. The SSG enables interference sources to be located without the assistance of a second satellite by performing the geolocation operation directly on the interference signal itself. 


Meanwhile, the GS380L Geolocation Signal Enhancement System was designed to dramatically improve the performance of geolocation systems. The product separately processes the signal of the primary satellite and its side-lobe replica on the adjacent satellite, virtually cloning the interference signal and the replica and then processing these clones to yield the required geolocation results. The GS380L is compatible with both the Model 8000 and the SSG.

The GVF has become the single and unified voice of the global satellite communications industry.  It brings together organisations engaged in the delivery of advanced broadband and narrowband satellite services to consumers, and commercial and government enterprises worldwide.

Headquartered in London, with a regional office in Washington DC and global affiliates, the GVF is an independent, non-partisan and non-profit organisation with 200+ members from every major region of the world.  The broad-based membership represents every sector of the satellite industry, including fixed and mobile satellite operators, satellite network operators, teleports, satellite earth station manufacturers, system integrators, value added and enhanced service providers, telecom carriers, consultants, law firms, and users. 

Integrasys was founded in 1990 to provide signal monitoring software systems for the satellite, broadband and telecommunications markets. The company offers a variety of interference monitoring solutions, including Vectorsat Carrier Under Carrier Interference Detection, Controlsat Carrier Spectrum Monitoring and Satmotion SNG.


Satmotion Pocket is a VSAT auto-commissioning system that minimizes deployment time, effort and interference. The solution measures Copol, Xpol and ASI, feeding the data back to the installer to provide options for the best VSAT installations. Key benefits include an immediate return on investment (ROI), no communications required between VSAT installer and NOC/hub operators, and a simple user interface available on Apple, Android and laptop devices. Satmotion Pocket is fully scalable, and can be used for up to 10 concurrent users. 


Alusat, an automated network maintenance system for minimizing the maintenance time, effort, and intra-satellite interference or any service degradation, is the latest evolution of Integrasys’ Satmotion Pocket. With Alusat, users can virtually visit and maintain established VSAT networks, ensuring continued optimization of operations, while minimizing costs caused by service failures and site re-visits. In certain conditions, it can even recover out-of-service terminals. Users can determine Rx and Tx thresholds, as well as automatic actions to be taken in different circumstances to rectify problems. 

Kratos provides integrated end-to-end ground system solutions for satellite operators, telecommunications providers, broadcasters, and the military sector, among others. It has a major collection of interference detection, geolocation and mitigation solutions, and a wide variety of expertise boosted by its ownership of Sat Corporation and VeriSat. 


The Monics product suite is a carrier monitoring system that uses algorithms to automatically determine that the signal to noise ratio of a carrier is impaired, identifies the presence of an interfering carrier, and generates the characteristics of the interference. If abnormal bandwidth performance is detected, alarms are displayed and alerts are sent to an operator. Additionally, when integrated with a service level monitoring system such as Neuralstar SQM, Monics quickly alerts the operator or service provider that service level agreements are impacted, and prioritises the mitigation of impacted services to minimise the effect on the bottom line.  


satID is Kratos’ all-in-one interference location solution when integrated with Monics. It uses a map-driven user interface to provide operators with the ability to perform geolocation scenarios effectively and efficiently. With its patented Ephemeris Error Compensation (EEC), accuracy is dramatically improved to within 5km of the interfering signal. 


SigX Protect bridges the gap between monitoring and eliminating interference using advanced cancellation algorithms to remove interference while protecting the desired signal. SigX Protect is installed at the receive end of the communications chain only, adding minimal delay or latency, making it an ideal solution for point-to-point, point-to-multipoint and cross-beam applications. Received RF signals are passed through the SigX Protect system, where any interference is cancelled out, and delivered to existing customer hardware for normal processing.


SatGuard identifies VSAT terminals causing Xpol or ASI by extracting the terminal ID from the operational link bursts, synchronising the operational and interfered link, determining the interfering bursts, and correlating the information to determine the terminal ID causing the interference. This enables operators to resolve VSAT interference in a matter of minutes. VeriSat has also developed a user-friendly solution to determine GSM base station location by decoding the GSM interference and extracting the country ID and unique cell ID.

The Satellite Interference Reduction Group (IRG) is the global industry organisation, whose mission is to combat and mitigate radio frequency interference (RFI) for an interference-free Satellite Frequency Spectrum.

There are a number of tools, technologies, and processes already available to reduce interference and our goal is two-fold: firstly we are working to help the industry understand what those are and how to use them effectively; and secondly we are constantly looking for new and better ways to fight satellite interference.

SkyMon is the satellite carrier monitoring and interference localization solution that lets you identify interference and manage carriers in one comprehensive system while minimizing your investments. SkyMon modular architecture can be customized to integrate with your existing infrastructure.
