Moreover, the seismic acquisition equipment has been designed based on a low cost electromagnetic sensor, which has been conditioned to achieve our goals.
The key advantages of such optical wireless systems are usage of flexible unlicensed spectrum, high data rate support, energy efficiency, no electromagnetic interference, low-cost front ends, and inherent security.
We detail the encoding, operators and a repairing procedure applied to obtain good solutions in terms of coverage, cost and electromagnetic pollution.
The non-invasive, time- and cost-effective electromagnetic induction sensor was found to offer new perspectives to reconstruct and analyse in detail the Quaternary paleotopography beneath the loess cover.
Candidate magnetic materials are discussed in terms of minimizing the cost while meeting electromagnetic performance characteristics.
Combining laser scanner altimetry data that is readily available to low cost GEM-2 electromagnetic surveys, allows for the refinement of the local geological model.
It combines 1 50 000 lithostratigraphical models of the subsurface, archived geological and geotechnical data, airborne laser surface altimetry data, walk-over survey observations, and low cost geoelectric and electromagnetic data, in that order.
A powerful, low cost, highly efficient electromagnetic energy source would need to be developed.
The motivation is to reduce their size, cost, processing noise, electromagnetic emission and especially power consumption, as they are most often powered by batteries.
It is also thought that over time, this approach may be more cost effective than electromagnetic systems, something that will not be known until commercial system begin to operate.
