Terravision Exploration's GPR, also known as GPRplus™ is a ground-scanning device, that verifies and investigates the presence of mineral resources and geological features, with unrivalled clarity and speed up to 200m.
Terravision Exploration was one of the first companies to take advantage of the deep imaging GPR systems commonly referred to as GPRplus, DPR or DGPR. In ideal conditions these unique systems can penetrate up to depths of 200m and have provided ground breaking resolution of the unseen around the globe. Terravision Exploration has been at the forefront of GPRplus operations since the emergence of the technology and is proud to see the international adoption of GPRplus solutions. Building on our pedigree of championing new concepts Terravision Exploration is leading the charge on new technologies across the geospatial industry.
It is not widely known that the GPRplus has its origins in space exploration. Low frequency signals have been purposefully used to explore extra-terrestrial environments such as the moon. Low frequency ground penetrating radar was used to map the lunar sub-surface up to a depth of 2 km during the Apollo and LUNA missions.
frequency signals here on earth. The difficulty is, unlike in space,
ground conditions on earth have a much higher water content
works because it is has a higher dynamic range than other GPR
Note: Dynamic range can be compared to the 'currency' of
penetration. The more you have, the deeper you can penetrate
effectively. Traditional GPR units are able to achieve a dynamic
range of 96dB after extensive amplification and pre-processing
126dB in the primary band - before any filtering techniques have
