Airborne Gravity 2010 The TAGS acquisition software (Figure 6) was designed for minimal user intervention to reduce operator errors, and to increase reliability and ease of use. The important operating parameters of the system are displayed on screen to enable ‘at a glance’ quality control (QC) so that a flight line may be repeated immediately if necessary with minimal wasted flight time. It also features an enhanced predictive tracking algorithm which calculates the approximate gravity value while the system is in transit from the airport base to the survey site and during aircraft turns while on survey. This feature greatly reduces the time the system would otherwise take to settle down into the range where it can properly read gravity. Aside from QC of the gravity data, the operator selects which flight mode the system should be in (transit, online, turning or landing) and the system takes care of all of the appropriate calculations and adjustments. In addition to recording the gravity data on an internal hard drive, the system outputs data to a serial port which can be connected to a laptop computer for real time data backup and to also control the main software. Results Flight testing of the system began in late 2006 and continued through until mid-2008 using several different aircraft and locations. Many refinements were made to both hardware and software during the testing program to bring the system to a consistent level of performance which met the specifications for both hardware and processing software. At the end of the testing phase, a survey was carried out over a known test area in South Africa which showed conclusively that the system was meeting the original performance goals (Figure 8). Periodic testing ensures that system performance is maintained in terms of repeatability and comparison with ground gravity data (Figure 9 and Figure 10). Figure 8. Comparison of TAGS data obtained during system testing in South Africa over the Vredefort Dome and ground vertical gravity data. 33
Airborne Gravity 2010 Figure 9. System acceptance testing in Florida in early 2009 showing stacked repeat line free-air anomaly data. The data had a repeatability standard deviation of 0.63 milligals with a 5 km filter resolution. Figure 10. Free-air anomaly results obtained during system testing in Florida showing correlation with ground vertical gravity data. The standard deviation of the differences is 0.51 milligals with a 5 km filter resolution. 34
