QuadSAT’s system is a key disruptor within RFI mitigation; its low-cost and flexible solution transforms accessibility to high-quality testing within satcom. The system provides pre- and post-flight software to ensure repeatability, control over the drone during measurements, ease of operation and data delivery in a uniform format. This in-depth testing will provide quality assurance and improve reliability throughout the satcom industry, allowing the industry to deliver the networks required for the connectivity of the future.


Thanks to the ARTES Core Competitiveness programme, QuadSAT will work on a productised version of its solution that can be operated directly by users. This will help significantly scale the technology and make test and measurements of satellite antennas much more accessible, anywhere in the world.


3 reasons RFI is a current issue within Milsat

Radio Frequency Interference has been a longstanding issue within satellite and the military’s use of satellite communications is not immune from the problem. RFI has been closely monitored for years and the creation of mitigation tools has been prioritised within the industry. However, how does the rapidly changing landscape within space affect RFI in 2022? Here are 3 reasons RFI must be evaluated and addressed with new solutions:

1.    The changing use of multiorbital space 

Lower and Medium Earth Orbits are currently seeing a drastic overhaul in use; mega constellations are being launched, and new entrants are establishing themselves within commercial markets. LEO ground segments are far more complex than those previously seen within satellite. LEO mega constellations are primarily utilising Ku and Ka bands as they offer greater throughput in smaller dishes. The need for test and measurement increases with greater directivity as it increases the likelihood of RFI and the severity of its impact on services. Additionally, due to low orbital altitude, tracking and switching through multiple gateways is standard practice and therefore the monitoring of tracking accuracy and satellite acquisition quality during handovers will be critical in managing the sector’s use of spectrum and preventing RFI within military.  

2.    Multiple constellations using the same bandwidth  

Within GEO, there is usually one entity in a frequency band per orbital slot meaning that coordination mitigates interference caused by ‘border issues’ between satellites in adjacent slots. With LEO, however, we have potentially multiple constellations using the same frequency bandwidth. Each constellation is in multiple orbits and orbit heights. This could potentially lead to valid transmissions from authorized satellites causing interference at any given spot on the earth with the interference being intermittent and different at any given location. Within military operations it will be critical to ensure that operators have access to in-field tools to identify and mitigate RFI.


3.    5G’s operational impact on satellite 

5G has delivered fresh challenges within spectrum management, with two industries with differing needs working closely within spectrum. RF noise is a considerable issue caused by the high number of 5G cells required to run an effective network. There is a risk that signals within the wider spectrum will become overloaded. Technology has been developed to mitigate this, however there is anecdotal evidence of satellite signals being negatively affected by 5G responders. 5G adds another layer of risk of RFI and satellite users must take steps to monitor and control its impact to prevent loss of services. 


How can satellite manage new RFI challenges?

As the RFI landscape changes to reflect the developing use of space, it is critical that satellite users build robust solutions to safeguard teleports from incidents. Perhaps the most obvious solution: ensuring that the ground segment has access to suitable testing and monitoring technology is key in enabling successful management of the ground segment. Making on-site testing available and cost effective, teleport operatives can utilise accurate results to take the necessary steps to mitigate disturbances with the knowledge that amendments are cost-effective, necessary and will be successful. Great quality equipment paired with rigorous and thorough testing and monitoring solutions is going to be key in mitigating incidents and maintaining reliable communication channels.

Demonstrating drone-based antenna testing to Cyta, Eutelsat, and Hellas Sat

The last couple of weeks has seen teams from QuadSAT set off to both Cyprus and France to provide in-depth demonstrations of our latest technology. In Cyprus, we provided demonstrations for the dominant telecommunications provider, Cyta, and premium satellite communications solution provider, Hellas Sat. At Cyta’s Makarios Tier-4 certified teleport, we performed antenna tests which comprised of raster scans, azimuth cuts and elevation cuts. We demonstrated our antenna testing and validation for Eutelsat, in which we measured a 3.8m bat wing antenna at distances in excess of 700m. We provided results to each organisation within 7 days, allowing them to receive quick feedback on how their antennas were performing within their own environments.

Maintaining antenna accuracy and its original specified performance is crucial in delivering and maintaining world-class services to customers and performing on-site antenna testing and verification can transform RF management. 

Here are 3 reasons to invite us to demonstrate its drone-based testing system:

1. Review how your antennas are affected by their environment

Environmental factors impact the success of an antenna’s mission; reflections impact the journey of RF signals and can result in RFI incidents. Geographical features such as hills, mountains, trees, and other environmental features, such as other nearby antennas, are potential sources of reflection, even if not in the direct line of sight. Antenna testing within testing ranges clearly can only evaluate the antenna itself, and not the impact of external factors on its performance. Testing on-site using drone-technology is a flexible and effective way of gaining accurate results.

2. Reduce downtime

Downtime is a costly consideration when building testing and verification into schedules. When testing must be performed at a test centre, time and money must be spent transporting the antenna to location, all whilst the antenna is not performing, and therefore not producing revenue. Ultimately, this can even deter ground segment operators from testing altogether, delaying problems and potentially resulting in degradation to services. QuadSAT’s technology is quick to set up and reduces the downtime required to perform antenna testing.

3. Improve cost efficiency within testing

Many antennas are logistically difficult to reach, creating challenges in terms of current testing methods. If an antenna is in a remote area, it can be costly to transport it to a test centre. Additionally, with the introduction of LEO constellations and the resulting increase in the number of ground segments required, costs associated with transporting antennas can quickly rise beyond what is financially viable. Testing and verification performed by drones drastically reduces the costs associated with testing and verification strategies, whilst delivering accurate results.

As the ground segment expands to establish connectivity to both new and existing orbits, testing capabilities must adapt to deliver in-depth and cost-effective results. By improving accessibility to high-quality testing solutions for the ground segment, operators can utilise testing to improve services for their customers. The system ensures repeatability, control over the drone during measurements, ease of operation and data delivery in a uniform format, providing quality assurance and improving reliability throughout the satcom industry. Drone-based testing, calibration, and verification will enable the networks required for the connectivity of the future.
