Our innovative Latro solution!
Latro is our agile push-cart subsurface reality capture solution for underground defects and utility locating. In more technical lingo, it’s a 3D GPR system utilising Noise-Modulated GPR (NM-GPR).
While this innovative piece of tech might look like a simple but quirky lawnmower, it is far from simple. The Latro system can rapidly map high-resolution underground features to survey grade accuracies, where it is the perfect technology for pavement, sidewalk, footpath and road projects amongst others.
In layman terms, Latro’s advanced on-board computer, innovative radar tech, compact design, and maneuverability enable locators to quickly locate underground utilities by pushing a cart back and forth over an inspection area. Latro can scan up to around 3 metres, depending on ground conditions, it also takes imagery of the surrounding areas above ground.
Latro notably integrates Earth Radar’s multi-channel & multi-directional 3D-GPR technology with survey grade positioning, which allows the system to rapidly map high-resolution underground features to survey grade accuracies. As a result, this technology can rapidly scan large areas to accurately map underground features and generate high-resolution and survey grade deliverables, making it perfect for a variety of underground locating and utility mapping initiatives.
“Key features include dual polarisation and high-resolution 3D GPR; while still punching deep. The system produces clear and sharp 3D images of the subsurface allowing increased target discrimination, while still imaging to depths of over 2 meters,” said Bryan.
Through the integration of survey grade positioning via either Total Station tracking or RTK GNSS, the resulting 3D-GPR dataset can be post-processed and analysed in context against other plans, records or survey information.
A major limitation of traditional GPR systems requires that you are scanning perpendicular to the object you are trying to find. The reality is that within a road and footpath corridor you will have pipes, conduits and assets orientated along many different directions.
Using a traditional GPR requires multiple time consuming sweeps of a site in at least two different directions to complete a survey. The Latro’s multi-channel and multi-directional antenna configuration allows you to see everything beneath the ground from just a single scan.
