Contech News: Topcon invests in DDK Positioning

Topcon Positioning Systems announces its strategic investment in Aberdeen-based DDK Positioning Ltd.


Topcon Positioning Systems has just announced its strategic investment in DDK Positioning Ltd. DDK is an Aberdeen-based specialist in GNSS (Global Navigation Satellite Systems) receivers and PPP (Precise Point Positioning) correction services. However, both parties remain relativity tight-lipped with regard to how much Topcon is investing in DDK Positioning.

Global positioning

DDK Positioning delivers its services exclusively over the Iridium® network. Consequently, it can provide a very accurate augmented global precision positioning service. This is what particularly attracted Topcon.

Topcon VP of Emerging Business, Ian Stilgoe tells us:


“For a number of years, Topcon has been a supplier of core GNSS components to DDK Positioning to deliver their MAX services. With the expansion and growing success of this business, specifically in the Marine sector, a closer cooperation will ensure optimal integration for the highest possible accuracies and performance in the most demanding applications,”


DDK Positioning CEO, Kevin Gaffney added, “This partnership provides an extraordinary opportunity for our two companies to work together in pursuit of our shared ambition — providing a robust, resilient and truly unique GNSS positioning service”

He continued, “We are extremely excited about partnering with Topcon and it’s a great fit for DDK Positioning, not only will it allow us to continue to develop best in class positioning services, we will also be able to continue to grow the company and expand our services globally.”

Millimetric accuracy

DDK’s GNSS correction system enables clients precisely to locate and track their assets globally. Furthermore, its system can achieve a positioning accuracy of less than 50 millimetres, compared to the typical GPS accuracy of around 10 metres. Therefore, its uninterrupted delivery of the service, along with independent verification of precise position is of great value to Topcon.

Its precision significantly enhances positioning accuracy for critical industrial applications. It is also what differentiates the DDK from its competitors. As Topcon invests in DDK Positioning, it is also worth that reiterating  DDK’s exclusive partnership with Iridium Communications Inc.

Iridium. is a publicly traded American company with headquarters in McLean, Virginia. Significantly, Iridium operates the Iridium positioning satellite constellation. This is a system of seventy five error-correction satellites. Sixty-six of these satellites are active, whilst the remaining nine function as in-orbit spares.
