PROJECT NAME: r4sa, r4sa ext I&II

PROJECT TYPE:  Local - Surveillance

PROJECT OBJECTIVES:

  • The CAPEX plan submitted to and approved by the Regulator and the users in 2003 identified the need for the replacement of the L Band en-route radar at FAJS ATSU as well as the Sutherland en-route secondary surveillance radar. This was due to the normal replacement cycle and age of these surveillance radars.
  • The replacement of the en-route radar at FAJS with approach radar - co-mounted primary and secondary mono-pulse radar allowed for the reduction in separation within the FAJS ATSU terminal area (TMA) from 5nm to 3nm with the associated capacity increase and a fully redundant radar service. Upon a successful commissioning and flight trial, the radar has been attached for operational use.
  • The Sutherland primary radar reached the end of its useful life and was withdrawn from service. It has not been replaced, as the primary radar service is not required for en-route surveillance. Upon a successful commissioning and flight trial, the radar has been attached for operational use.
  • A need was also identified for a second approach radar at FACT, in order to provide improved radar redundancy and reduced radar separation with a resulting increase in capacity. Upon a successful commissioning and flight trial, the radar has been attached for operational use.
  • The primary radars at FAEL and FAPE ATSU have been replaced with new approach radars and as part of an extension of the project r4sa contract. Also with the extension of the r4sa contract, an approach radar for the ATA, secondary radar for FABL have been installed and commissioned. The FAGG secondary radar and an approach radar for the new airport at La Mercy have been procured and civil works/installation is in progress.
  • A TCU has also been installed and commissioned at FAEL ATSU. In addition, two TCU installations and commissioning are planned for George and the new airport at La Mercy.

PROJECT SCOPE:

  • New approach radars consisting of co-mounted primary and secondary Mode S surveillance radars have been installed at FAJS, FACT, FAEL, FAPE and ATA.
  • En-route mono-pulse secondary radars with a Mode S capability have been installed at Sutherland and FABL.
  • The installation of an approach radar and secondary radar - together with associated TCU installations- is currently in progress at La Mercy and FAGG respectively.
  • A TCU has been installed and commissioned at FAEL ATSU to display the tracks from the radar sensor.

The scope includes/included additional works like:

  • Civil works - site preparation and construction of a concrete tower
  • Electrical provision and installation
  • Air conditioning
  • Fire Protection and intruder alarm
  • Communications Infrastructure
  • Radar dome works
  • Hoisting equipment
  • Standby generator and UPS systems
  • Professional fees
  • Flight trials
  • Emergency tower for FACT
