NSTALLATION, INTEGRATION, AND CHECKOUT
9.1
INTRODUCTION
This section contains installation data and initial tune-up procedures for the Model 1150A Doppler VHF Omnirange
(DVOR) electronic subsystem. Refer to the appropriate equipment manuals for specific antenna installation and
siting requirements. Before the equipment is installed, shelter construction must be completed. After equipment is
unpacked and inspected, the installation work is divided into two major sections.
a. Site construction work consisting of the concrete, antenna counterpoise, shelter, primary AC power
installation, and DVOR system hardware is completed first. At sites where SELEX Sistemi Integrati Inc.,
does not supply the antenna counterpoise, shelter, or primary AC power, the customer or end user is
responsible for these items and their installation.
b. The DVOR transmitter is then powered up and aligned.
9.2
SITE INFORMATION
All structures (buildings) within 200 meters feet of the station shall be removed. No groups of trees shall be within
200meters or subtend a vertical angle of more than 2 degrees. Farm type wire fences about 1.2 meters high are not
permitted within 120 meters and chain link type fences (6 feet high) are not allowed within 500 feet. Overhead
power and control lines may be installed beyond 100 meters but should be essentially radial to the station for a
minimum of 100 meters. Power and control lines to the station should be buried underground within 100 meters of
the station. There should be no lines or supporting structures that subtend a vertical angle of 1.5 degrees as measured
from the station ground elevation.
All other conditions and considerations applicable to specific sites should follow specifications of Eurocae ED-52
Figure 18, and ICAO Annex 10, Part 1 Volume 1, Attachment C, Paragraph 3.2, VOR Siting Guidance.
9.2.1
Shelter Requirements
The DVOR requires a shelter which is located under the counterpoise. The building must not extend beyond the
counterpoise edge.
9.3
UNPACKING AND REPACKING
The DVOR electronic subsystem is shipped unassembled. Only general precautions can be given because the crating
and unpacking depends upon destination and which optional equipment is included. Most items are packed
separately in individual containers; these are then grouped for crating. Each crate contains a packing list which
details what equipment is enclosed in the crate. Unpack the equipment and visually inspect each item for accuracy
and damage, but DO NOT REMOVE any ESD protective wrapping. Report any damage immediately. After
inspection, repack each item to prevent damage. During installation, unpack items as they are needed.
9.3.1
Environmental Considerations
The environmental conditions must not exceed those listed in the Specifications of Table 1-1.
9.4
INPUT POWER REQUIREMENT SUMMARY
The requirements for input power must not exceed those listed in the Specification of Table 1-1.
