Description

Over the last five years, TEMPEST development efforts have centred around extending bandwidth, improving system geometry measurements, improving the signal processing and making the system more robust, integrating additional instruments on the platform, modernising hardware and building additional TEMPEST systems. Pioneered by Geoscience Australia's AUSAEM project, global demand for regional and country scale Airborne EM has increased significantly. The data is being used for a broad range of applications, with geophysical mapping to improve the understanding of geology at regional scale and mapping the thickness and character of the regolith remaining popular use of the data. However, increasingly TEMPEST data is being used for groundwater resource assessment, -evaluation of the effectiveness of in-fill EM in particular areas and by some innovative companies and individuals to aid in the search for critical minerals. This paper presents a summary of the improvements currently in development and/or implemented on the TEMPEST system since the AEM 2018 conference and how these efforts were designed to improve the platforms utility as a cost effective and capable regional Airborne EM mapping system.
