New Drone GPR

Groundradar has designed a 100 MHz drone GPR system for specific applications where rapid, non-contact, near-surface scanning is required.  The system is currently being tested in South America, but preliminary tests have shown that penetration to 10 m is feasible in suitable soil conditions.  In frozen environments, penetration to beyond 100 m should be possible.  The entire system is designed to be mounted on a low-cost DJI-type drone, and weights 500 g, including RTK GPS rover, antenna and on-board data storage.  The battery will last approximately 4 hours continuously. 

Groundradar visits Haiti

Groundradar recently visited Haiti to examine the use of radar technologies for possible mineral resources on the island.  Visits were made to the south-west of the country to test UltraGPR on various terrains, with encouraging results. 

New Groundradar Studio Software

Groundradar has released Groundradar Studio software, which enables users and clients of UltraGPR technology to view and manipulate their data.  Radar profiles and interpretations, provided in a encrypted file from Groundradar, can be opened in Studio for viewing.  The software allows users to modify, delete and add interpretation.  Most importantly, the software allows users to ensure that tie-lines match perfectly using an interpretation mis-match algorithm which highlights where issues occur.  Users can also add new interpretations as required.  Maps are linked to Google, Bing, Yandex and OSM on-line map sources, showing results overlain satellite images or vector maps.

All interpretations may be exported as ASCII files or DXF surfaces.  In addition, the radar data may be exported as point cloud data (Leapfrog), SEGY (Gocad, Surpac, Datamine, etc) and other radar formats.  Finally, sections can be created automatically, with scales, inset maps, logos, etc in PDF or BMP format at the click of a button.

RTK DGPS now built into UltraGPR systems

The latest generation of UltraGPR now includes an RTK GPS receiver and helical antenna for adequate satellite reception from ground level.  The incorporation of an on-board GPS simplifies the design of the system and facilities faster use. 

Extensive on-going surveys throughout Indonesia

Groundradar’s Indonesian partner, PT Geosearch, has been conducting on-going GPR surveys throughout Indonesia for nickel laterite, bauxite, alluvial tin, and coal applications.  Due to increased demand and the commissioning of local processing facilities, the demand for Indonesian nickel laterite has grown dramatically in the last year.  A user has uploaded an UltraGPR system being used on a laterite deposit on Sulawesi Island to YouTube:

Groundradar signs MOU with Afghanistan

Groundradar attended a commercial meeting in Mumbai, India this week as a guest of the US State Department.  The purpose of the discussions was to bring modern geophysical methods to Afghanistan, both for mineral prospecting and geotechnical investigations.  Groundradar has signed an MOU with Afghanite of Kabul and Global Venture of Florida to provide radar technology to Afghanistan’s private sector, as well as geophysical training workshops in Kabul in the near future.

On-going well pad surveys in Papua New Guinea

Groundradar continues to survey new and re-worked wellpads as part of the PNG LNG project, with three visits to Papua New Guinea between June – September, 2018.  The UltraGPR systems being employed for these projects are continually improving with deeper penetration through faster real-time sampling ADC chips, more precise positioning with RTK DGPS systems and better data processing and presentation software, all developed in-house.
