Banska Bystrica, Slovakia -- When T-Com, the fixed line business division of Slovak Telkom Group, recently undertook to map its underground fiber optic communication cable networks, it wanted a method that could be easily done by existing work crews. T-Com found the answer in a complete field-ready, mobile solution consisting of a SebaKMT i5000 cable locator paired with an Ashtech MobileMapper CX GPS/ GIS handheld running Geolantis ATLANTIS GIS software. Ornth s.r.o., the Ashtech Dealer in Slovakia, delivered on-site GPS training to T- Com technicians who are now able to locate all lines, accurately survey the network and update data.

The SebaKMT i5000 multi-frequency line location system induces a signal into the cable enabling field crews to find and follow the underground network. The locator can measure the position, the current intensity and evaluate the distortion of the signal.

Collected data is transmitted via Bluetooth to an accompanying Ashtech MobileMapper CX GPS/GIS handheld, which also displays a geographic map of the cable’s position. The signal attributes, the position and depth of the cable are registered into the ATLANTIS-software running on the MobileMapper CX. Thanks to the Ashtech GPS handheld, field crews can simultaneously navigate to the site,  locate the cable, survey the network with precision and keep all map-data up to date for high- quality asset management. Additionally, with the aid of Ashtech’s FAST Survey software the field crew sees in real time a graphical, scaleable background map displaying the cable’s position as a colored line as it is being followed.

The MobileMapper CX GPS handheld was chosen to be paired with the SebaKMT i5000 because of its sub-meter real-time accuracy, ruggedness, and ease of use. Its Microsoft Windows CE open platform enabled the ATLANTIS-software to be seamlessly integrated and easily configured to receive and process the data from the i5000 cable locator. The new hardware software solution has enabled T-Com to reduce the time and cost required to map and manage its telecommunication network.
