Replacement of the DVOR and associated Remote Control and Monitoring System is required. HIAL intends to re-use some, or all, of the existing infrastructure including the counterpoise, cabin, electrical systems and intersite connectivity.

HIAL requires the capability to provide a DVOR service within the published DOC. User and technical system requirements are included in the Tender Pack.

The capability shall be delivered compliant to all applicable regulations, with minimal impact on Kirkwall Airport’s operations, by upgrading, replacing or adding to the core components of the current DVOR.

HIAL intends to re-use some, or all, of the existing infrastructure including the counterpoise, cabin, electrical systems and intersite connectivity, with the caveat that these are part of a system installed 30 years ago and will have aged accordingly.

The successful technical solution will involve the replacement of the DVOR electronics and associated Remote Control and Monitoring System and the re-use of each of the existing cabin, counterpoise and DME.

DVOR and DME antennas are to remain at the current coordinates.
