The triangulation stations are a common feature across Great Britain but they have become dated in the face of technological advances. GPS offers Ordnance Survey surveyors a more effective and accurate way to survey the landscape. It requires fixed points on the ground that can be used to triangulate the signal from overhead GPS satellites. Greenwoods Communications was given the task of designing and developing a series of base stations that could survive the elements yet protect the sensitive and expensive equipment needed to operate a GPS network.

After an exhaustive hunt for a specialist provider, the Ordnance Survey identified Greenwoods as one of a small handful of companies that had the necessary knowledge and expertise to deliver the base stations. Greenwoods was appointed in July 2003 and spent the next four months agreeing and perfecting the specification. The final design was agreed in January 2004 and an order for 35 base stations was placed with options for more as the network progresses. The base stations will be called-off as the network is rolled out.

"The success or failure of the new GPS network depends to a great degree on whether the base stations function as effectively as intended. Greenwoods has perfected the design to a point where it exceeds the required standard and we are confident that the new base stations will protect our equipment from the extremes of the British weather. The base stations have been manufactured and delivered to schedule allowing us to roll out our GPS network in a timely fashion," said Richard Short, Chief Surveyor, Geodetic surveys and Computations, Ordnance Survey.

"We appointed Greenwoods because they have a proven track record in delivering telecom services, offered best value for money and demonstrated a willingness to go the extra mile to meet our exacting standards. Their ability to adapt to our requirements is a measure of their professionalism and willingness to deliver a genuine tailored service," he added.
