GPS control survey for Inertial Measurement Unit (IMU) in pipeline detection tool.

Using GPS, we measure traps, welds and control points along the pipeline in order to correct the IMU drift. This correction is done through in house software. This method will minimise dig time and costs when locating the defects and anomalies.

"Their deep understanding of GPS and rigid
quality controls has particularly impressed us"

Merrett Surveys have vast experience providing GPS surveys for AGM (Above Ground Marker) locations associated with IMU based pipeline mapping. We have skills to optimise the accuracy of your mapping system. Detailed reports enable crews to set out AGM's accurately and swiftly.
Field mapping required before the design of oil, gas and petroleum pipelines is a service we also provide. We can do this using aerial mapping with photogrammetry or airborne laser scanning - Lidar, or ground based in field GPS or DGPS methods.

We use the latest technology such as SmartNet, this Real Time Kinetic Network allows for faster processing times whilst maintaing accuracy. We have experience of using GPS worldwide, our most prestigous project to date has been to assist the UN with defining the International Boundary between Nigeria and Cameroon. We specialise in the provision of GPS and survey support for pipeline mapping projects worldwide.
