Project Name: TeRNS (Terestrial Radio Navigation System)
Project Type: Local – Navigation
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 and is becoming increasingly difficult to maintain due to equipment obsolescence.
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;
- 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 are now operational:
|Aggeneys (AGV)||Grasmere (GAV)||Greefswald (GWV)|
|Hartebeespoortdam (HBV)||Heidelberg (HGV)||Phalaborwa (PHV)|
|Witbank (WIV)||Ladysmith (LYV)||Sutherland (SLV)|
|Nieuwoudville (NVV)||Victoria West (VWV)||George (GRV)|
|Mafikeng (MMV)||Welkom (WMV)||Durban (DNV)|
|Pilanesberg (PNV)||Standerton (STV)||Greytown (GYV)|
|Warden (WRV)||Kimberley (KYV)||Petrusville (PVV)|
|Greyton (GEV)||Sishen (SSV)||Port St Johns (PJV)|
|Alexander Bay (ABV)||Bloemfontein (BLV)||Cape Town (CTV)|
|East London (ELV)||Pietermaritzburg (PMV)||Port Elizabeth (PEV)|
|Richards Bay (RBV)||Johannesburg (JSV)|
A completely new DVOR/CVOR/DME training system was installed at the ATA. Training of students will include this equipment as well as the MCS (Maintenance Control System). A new CBT (Computer Based Training) system is designed to support trainers and trainees in their training.
Sites to be completed
Ceres is a new DVOR/DME installation and the commissioning of this facility is scheduled for 19 November 2009.
The Monitor System Upgrade must be done to get the facility on the same standard as TeRNS and commissioning is scheduled for 24 September 2009.
A new DVOR was installed and commissioned. The facility will be operational soon, but the date will be determined depending on the AIRAC (Aeronautical Information Regulation and Control) cycle.
La Mercy (TGV)
As this is a new airport, a new DVOR/DME will be installed and the commissioning is scheduled for 11 March 2010.
Start date: 1st of July 2005
End date: 11 March 2010
