Innovative EM Technology
Monex GeoScope Pty. Ltd and Thomson Aviation Pty. Ltd. (www.thomsonaviation.com.au) are pleased to announce that they have jointly performed the requirements set by AMIRA to be a Supplier Sponsor of the AMIRA project “P1036A: Airborne Induced Polarisation – Stage 2”.
The new system arising from this project will be known as BIPTEM (B field, Induced Polarisation, Transient Electromagnetic). Depending on the target nature, the system can be flown in fixed ground loop, traditional in-loop, or long‑offset Slingram configurations.
Thomson Aviation and Monex GeoScope, with resource assistance from RMIT, have already made significant advances in all aspects of heli-borne EM surveys. Collaboration by these industry experts ensures this project will deliver significant advances on existing systems. All aspects of airborne surveys will be addressed from logistics, safety and aerodynamics, data acquisition, new high powered EM transmitters and sensor technology, through to innovative data analysis and processing.
System Testing and Development
Already a suitable sensor bird and towed array system stable enough to capture very low base frequency data has been designed, manufactured and flown.
This platform was utilised for the collection of airborne data over a test site at Orange in New South Wales. High quality B field and dB/dt data were acquired at 25 Hz, 12.5 Hz and even as low as 3.125 Hz.
Further testing and development will continue in 2017 and beyond, and it is hoped that BIPTEM data from known and understood EM test sites in Australia will be made available soon to demonstrate both the quality and resolution that BIPTEM will offer the industry.
