SPECTREMPLUSPower for better airborne geological and resources mapping. The new SPECTREMPLUS system is the most advanced fixed-wing airborne technologies, collecting high-resolution electromagnetic (EM), magnetic and radiometric data. With the highest power and advanced processing, the SPECTREMPLUS  system can simultaneously map shallow (1-100m) and deep (100-1000m) features with a higher level of resolution than any other comparable system. The SPECTREMPLUS system is one of the best fixed-wing AEM technologies.

A patented broadband transmitter square (100% duty cycle) waveform
High RMS dipole moment – new system: up to 1800 A 
Full Waveform recording – Recording and processing of 3- components of the secondary field. 
A stable platform (Basler DC3) and stable system geometry with high drag bird providing comprehensive parameterisation and 3D modelling of geophysical responses.

Wide bandwidth

For simultaneously achieving superior shallow and deep resolution. Effective high-resolution mapping of geology undercover

Real-time onboard processing

Allows for on-the-spot decisions

Step-Response processing

Outputting calibrated ‘B Field’ data

Interactive processing facility and detailed

Data interpretation

Insensitive to Superparamagnetic (SPM) effects (unlike currently available helicopter TEM systems).

Our multiple data sets provide integrated 3D solutions for geological mapping, exploration targeting, go-hydrological and geoengineering applications.

Geological Mapping

The broadband nature of the SPECTREMPLUS system, including B-field STEP response processing, results in the most efficient mapping of deep-mineralized zones in conductive environments. In addition, the SPECTREMPLUS system is an ideal tool for regional and detailed geological mapping given its large footprint.

Hydrogeology and Geo-engineering

The STEP response data is not spatially filtered (as is the norm with other systems) and the stable platform results in lower system noise levels at early times. Spectrem Air’s proprietary post-processing techniques enable detailed resolution of the first 100m of the sub-surface. This makes the system ideal for shallow aquifer mapping, environmental studies, and geo-engineering.
