Safe digging with S-GPR
ARESYS and SIRTI SPA developed S-GPR: an advanced GPR processing solution for real time utility mapping
Context
SIRTI SPA, company with a leading role in telecommunication infrastructures, developed an innovative mini-trenching solution, ONEDAYDIG™, that allows reduced realization times, also minimizing the environmental impact for the community (as described in ITU recommendation L.83). However, Sirti was not able to find a GPR – Ground Penetrating Radar – apparatus that matched the features required for its low impact mini-trenching technology.
ARESYS contribution
ARESYS developed a fully automated GPR processing software, that operates on a multi polarization 16 antenna array (3D GPR), specifically built by IDS. ARESYS strong know-how in algorithm design for exploration geophysics, along with its experience in high performance computing, allowed to implement a subsoil mapping tool (sGpr) that can process radar data and locate buried utilities, in real-time, on a consumer laptop, and without the need of skilled operators (as described in ITU recommendation L.84).
A friendly graphical interface allows to analyze buried utilities in 3D maps at a glance while acquiring. Moreover sGpr suite can be used to generate accurate reports of the acquisition campaign, enriched by georeferenced CAD maps, for improved productivity.
S-GPR one-pass real time solution has few practical advantages in respect to delayed data processing:
- there is no need of highly skilled operators;
- it correctly locates both in position and depth (and let the user easily mark) detected ducts directly in-field, without depending on external positioning systems;
- Planned trenching path and any path modification re-planned in-situ can be checked independently of access limitations to the survey areas;
- It can be easily adapted to different antenna arrays.
