Zupt’s B-PINS deliver precise stakeout locations in harsh environments during pipeline right of way where conventional survey methods are inefficient or ineffective. Field testing by pipeline stakeout professionals determined B-PINS is the choice for getting the job done accurately and productively at the lowest cost. A surveyor simply calibrates the B-PINS, walks the pre-determined pipeline route, processes, and adjusts the data, and imports it into a modeling package for precise horizontal and vertical coordinates of the terrain.
