Locata Corporation and Hexagon Mining have partnered to bring Locata technology to mines.

The JPS (Jigsaw Positioning System) is a radiolocation technology that replicates a highly accurate positioning network system, augmenting GNSS satellites with a ground-based positioning network.

Created in partnership with Locata, JPS provides the same positioning accuracy of GNSS, but without the signal drop-out in deep pits and against high walls.

LocaLites. Using a combination of fixed-position and movable LocataLites, a high-precision positioning network can be created where needed, complimenting or replacing traditional GPS. The LocataLites are solar-powered and contain an RTK GNSS receiver. They also have TimeLoc synchronization technology. Multiple signals are transmitted for redundancy and to mitigate multipath in the pit.

Module. One JPS receiver module contains two receivers. It has Ethernet and RS232 connections, and support for external GNSS corrections. A co-located antenna receives both GNSS and Locata signals.

Operations. Once the system is set up, users can monitor network health via an in-built web interface or reporting of the LocataNet status in the Jigsaw fleet management software, Jmineops. A web-based diagnostic tool is provided.
JPS can be customized and scaled to be any size needed, with LocataLites added or removed from a network as needed. JPS is interoperable with any Wi-Fi network.

No additional correction network means base stations, atomic clocks, data links, and differential corrections are not needed, reducing errors and infrastructure costs.
