Groundradar will be at Booth 507 at the Exploration’17 show in Toronto, October 23-25. In addition, Dr. Francke will be presenting a paper entitled “Realistic Expectations of GPR Performance in Mineral Exploration”, which discusses recent exaggerated claims of radar performance by “megawatt” radars and pseudo-radar technology such as ADR.
Groundradar is continuing to perfect a GPR system for the shallow bauxite at Weipa, Queensland. Following from initial studies by Groundradar in the early 2000’s, radar technology has advanced sufficiently that a custom system able to penetrate through the full deposit depth with a small, portable, instrument is now possible. The radar is linked to an RTK-DGPS for accurate positioning.
To improve on the existing Android-based datalogger employed by UltraGPR, Groundradar has developed a custom datalogger with a small wrist-mounted display. The device can accept data from multiple radar receivers at the same time, as well as from two independent GPS receivers. The primary GPS is a RTK-DGPS capable of positioning accuracy to within +/- 5 cm over base line distances of 10 km. A secondary GPS provides back-up position and location beneath vegetation to within +/- 3 m.
