Goble Pile Check (GPC) was pioneered by the late professor George G. Goble, Ph.D. - the father of Dynamic Load Testing (DLT). Dr. Goble is the founder of both PDI and GRL.
GPC is the wireless pile driving analysis (PDA) system of the 21st century - performed in accordance with ASTM D4945.
GPC system is supported by the three most powerful programs in the world, far superior to any existing programs by competitors. The three programs are:
GPC for data acquisition.
GPC Review for result reporting, which includes instant automatic signal matching (iN_GAPA) results in real-time.
N_GAPA (Nguyen Goble Automatic Pile Analysis) for signal matching analysis

Some of the features of the GPC system:
Users can use their own laptops
No signal degradation due to cable length and quality. System is wireless by design using IEEE 802.11.
Optional hardwire cable – the transmitted box may be connected by a low cost commercial off-the-shelf ethernet cable (very low cost compared to traditional DLT cable) up to 100 meters long.
Only 1 transmitter box for both sides of the pile.
Combination transducer – the strain gauge and accelerometer are combined on one bolt-on sensor minimizing pile drilling time and reducing complexity.
GUI has been purpose-built to be very intuitive and easy to use.

Dr. Goble's first generation of DLT was born in the 1970s (Pile Driving Analyzer®). And GPC was his last generation of DLT, before he passed away in 2017: https://rb.gy/nz5tl
