All surveys were conducted using swept frequency sources of C-Thru Ground's own design coupled to the ground either mechanically or through water. Broad frequency range generated by those sources, and recorded by the proper digital surveying equipment contributed to a high resolution of imaged ground features.
TRTTM applications licensed Olera Technologies and used by numerous tunnel developing customers in China.
