This is to allow the operation of heavy plant machinery and the stockpiling of material for the repair of the causeway. This work is being done for us by a contractor. We have been asked to close the site for safety reasons.
Stand-alone Furuno GPS receivers and equipment using Furuno GPS chips, could produce data that is 19.7 years in the past, therefore generating errors in both the GPS position and date (19th May 2002). The 19.7 year date error may result in instability in positioning, causing position errors, including failure of GPS position acquisition, etc.
