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
Sensor (i.e., Gauges) can be mounted up-side-down (i.e., inverted) or right-side-up.

Features:
Any laptops
No signal degradation due to cable length. System is IEEE 802.11 wireless.
Optional hardwire cable using a commercial Ethernet cable (very low cost compared to traditional DLT cable) more than 100 meters.
Only 1 transmitter box for all pile sides. Thus, no need to sync signals.
(other wireless system has 2 transmitter boxes - data arriving to/ from those 2 separate boxes not at the same time, and all sorts of algorithms needed to sync - most of the time successfully, but still a few times fails to sync the arrival times due to the T0 incorrect detection. GPC does not have this problem as data arriving to only 1 box).
Combination transducer – strain gauge + accelerometer combined on 1 bolt-on sensor minimizing pile drilling time / reducing complexity.
Very intuitive and easy to use GUI.

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
