The decision to update the equipment was made following a potential fatal collision on the A1 (M) which was visited by Chief Constable Della Cannings. Having seen PC Dave Taylor using a robotic total station, she asked him to prepare a business plan in order to purchase new up to date equipment.
Following demonstrations from the major survey equipment suppliers, a tender was drawn up and advertised. PC Dave Taylor was clear in what was required of a new system. "Any system we purchased had to be quick and have the facility for GPS work. This means that when there was no line of sight or if the scene extended over a wide area we could seamlessly switch from a total station to GPS cutting out the need for station set-ups. Our requirements for a robotic total station were that it had to be ‘future proof'. We were after all planning to spend around £80,000 of taxpayer's money! The data logger for both GPS and Total Station would have to have the facility to show a real-time plan to ensure that when we left the scene we knew that we had surveyed all that we needed. It also had to have a back lit screen and keypad so we could continue working after dusk. Finally, any system we purchased would have to be compatible with our plan drawing software ‘RelMo'."
Following the submission of tenders, the Unit purchased two Trimble S6 DR Total Stations and two Trimble 5800 RTK GPS with Trimble CU loggers (detachable control units). It was agreed that this system would provide the ‘connected survey' operation that would bring the greatest time saving benefits - optical and GPS data could be seamlessly integrated into a single data file whilst officers were still in the field.
