Stonehouse-based Lister Unified Communications have teamed up with Vector RTK Ltd which has created the UK's first truly independent privately-owned network of GNSS reference stations.

Real-time kinematic (RTK) corrections offer precise positioning to correct for common errors in current satellite navigation systems.

GNSS is used by millions of UK devices for precision positioning. This includes surveying, construction, farming, drilling, rescue and forestry. The list is almost endless and is of vital importance for UK business.

Tom Blumsom, IoT specialist at Lister Communications said: "Having a cost-effective alternative to the existing Global Navigation Satellite Systems will help our clients' businesses reduce costs and increase efficiencies.

"Many businesses use GNSS in equipment but are limited to suppliers. By contacting Vector RTK LTD, our customers could make substantial savings on their geo-location services."

In overseeing the general development of the network of (UK) GNSS reference stations, Vector RTK LTD needed reliable connectivity which needed to work consistently in a wide range of geographical areas.

From early testing, it became clear that SIMs on a single network wouldn't work in all the areas needed. The SIMs had to have the following key requirements:

• Excellent 4G coverage in numerous remote locations.
• Unsteered - no preferred "home" network but the ability to switch between multiple UK 4G networks automatically.
• Fixed IP for secure connection and remote access.
• Aggregated data - the ability to share data between SIMs to "level out" usage fluctuations.
• Technical support to assist with various aspects of rollout and device security.

Garry Davidson, managing director of Vector RTK said: "In Lister Communications, we have found the ideal solution and ideal partner. The SIMs work precisely as intended, and by reducing site visits and travel time, we have saved time and money.

"This has enabled us to create an effective infrastructure more quickly than anticipated. Lister has been excellent in providing real-time usage reports and technical advice to help iron out several teething issues. Their breadth of knowledge and experience has benefited our cyber security protections and enhanced the efficiency of our communications."

Mr Lister explained: "By using unsteered, 4G Multi-Network Data SIMs with Fixed IP, Vector RTK LTD can now extract data in real-time as well as securely access and configure equipment remotely. This enables changes to be made 'over the air', reducing the need for engineering site visits. This saves time and money and reduces the carbon footprint through reduced travel.

"Working with the Lister IT division (Lister IT Services), recommendations, changes and improvements to device configuration have enhanced the cyber-security protections and helped change how the network is configured to allow greater resilience and efficiency. We've quickly become a key partner for Vector RTK LTD and it's an exciting development for all the team here - being able to offer our clients the optimal network performance."
