The company can offer a range of positioning and surveying solutions to compliment the gravity data acquisition. The company own and operate Scintrex CG-5 (Micrograv) gravity meters and the latest GPS surveying equipment. The company can complete the planning, acquisition, processing and interpretation of gravity surveys using a variety of techniques in all types of terrain.\r\n\r\nGravity surveys have been carried out to estimate mass distributions within the earth for over 100 years. The real limiting factor in the widespread utilisation of the method was that each gravity station's level must be surveyed accurately. Most of the common gravity meters in use can obtain the gravity readings to a resolution of 0.01 mGal, which equates to a required resolution in height of 3cm. Previously, this level of precision was only obtainable by conventional spirit levelling. This made it expensive and time consuming and only utilised on small-scale detail surveys. On regional surveys, barometers (1-5m height accuracy) were used in Australia for many years while Inertial Navigation Systems (INS) have also been utilised on occasions.\r\n\r\nGPS has revolutionized the positioning and navigation industries around the globe and made 5cm positions and levels easily and reliably obtained for gravity surveys. This has lowered the cost of acquisition and greatly increased the utilisation of gravity as an exploration and evaluation tool.\r\n
