Project Name: TeRNS (Terestrial Radio Navigation System)

Project Type: Local – Navigation

DESCRIPTION

As a result of the GNSS delays the operational life of the existing terrestrial DVOR/CVOR/DME network must be extended to 2015 and will probable remain in service beyond that date.

The existing DVOR/CVOR/DME equipment (with the exception of those replaced under PRONAV1) has exceeded its operational life, is becoming increasingly difficult to maintain due to equipment obsolescence, requires excessive maintenance interventions and reliability is becoming problematic which impacts negatively on both service delivery and operating costs.

The TeRNS project was initiated in 2004 and encompasses the replacement of certain elements of the existing DVOR/VOR/DME network, the relocation of existing facilities where necessary and the establishment of new facilities as required by ATM operations to maintain the terrestrial navigation and conflict management service. The contract for this project was signed in July 2005 and the following facilities will be completed by the end of 2007.
