STATEMENT OF WORK

1.0 INTRODUCTION

The Naval Surface Warfare Center, Corona Division (NSWC CO), Performance Assessment Department, Code 44 (PA44), requires two (2) portable telemetry antenna systems used on the ADVANCED TELEMETRY SYSTEM – CLASSIFIED/UNCLASSIFIED (ATS-C/U) in support of the Air and Missile Defense Radar (AMDR) Project.

2.0 BACKGROUND

The NSWC CO, PA44 Telemetry Systems Branch facility has a requirement to support Program Executive Office Integrated Warfare Systems, Above Water Sensors (PEO IWS 2.0) for AMDR Telemetry System on USNS Martin.

The portable telemetry antenna systems are integral components of our shipboard portable ATS-C/U. These systems will be used to track and receive live missile and target telemetry data from radio frequency (RF) signals during scheduled events for this project. Data collected with this antenna system is used to assess performance and readiness of fleet combat systems. In order to meet these requirements, PA44 requires the portable telemetry antenna systems listed in the following specifications.

3.0 SPECIFICATIONS

Detailed Salient Characteristics for the Portable Antenna Systems are as follows:

3.1 General Requirements

The systems shall each be comprised of the following subsystems and assemblies:

Antenna control unit (ACU).

Dry air system.

Camera subsystem consisting of a lightweight boresight camera, and a remote controlled situational awareness camera Cables, hoses, hardware, etc. necessary to assemble the system.

Transit cases for shipment and storage.

The systems shall be designed to emphasize simplicity and reliability. The design shall facilitate ease of installation, operation, repair and maintenance, and transportability. Every effort shall be made to keep the end user in mind; the design shall minimize the size, weight and number of individual components. Size and weight of each component shall allow for movement and assembly by two people. Controls, displays and monitoring devices shall allow complete operation by a single operator. The system shall concurrently provide, except for mutually exclusive parameters, the performance specified herein without making any special adjustments.

The systems shall be designed with a 6’ (1.83m) reflector. However, it is required that the systems support an optional 8’ (2.44m) reflector. As described in section 3.1, it is highly desirable that the reflectors provided be identical to the existing NSWC Corona portable antenna segmented reflectors. Reflector information will be provided upon contract award.

All support material shall be manufactured of corrosion resistant materials. The completed reflector assembly shall maintain a surface tolerance, over the entire reflector surface, to keep gain reduction due to reflector surface variations to less than 0.5 dB. The reflector, support structure, and feed support hardware shall be constructed such that it may be disassembled with ordinary hand tools and packed into one or two shipping cases, which will be furnished by the contractor. Reassembly of the reflector and support structure shall take no more than 15 minutes and be such that it may be accomplished with ordinary hand tools.

3.2.1.4 Antenna Pedestal Subassembly

The pedestal design and construction shall provide for ease of accessibility to component parts for repair and maintenance. Replaceable parts shall not be permanently installed, such as by welding, riveting, or similar methods. The arrangement of parts shall be such that parts replacement, adjustment, and repairs are facilitated. Access covers and doors shall be provided where necessary to perform inspection, adjustment or service to enclosed equipment. Hinged covers and doors shall be equipped with devices to permit their retention in the open position and prevent accidental closing. The type and spacing of cover and door fasteners shall be consistent with the degree of enclosure integrity and frequency of access required. The pedestal shall be provided with azimuth and elevation axis manual locking devices. The elevation axis shall be capable of being mechanically locked in the 90 degree position. Indicators shall be provided at the control panel to show when these locking devices are in place.

Gear assemblies shall be designed to industry recognized allowable stress values, load characteristics, and satisfactory wear qualities. Provisions shall be provided for periodic lubrication. Backlash in the entire gear drive systems shall be consistent with servo stability and the locked rotor frequency requirement specified. Gearing backlash and quality must be consistent with recognized industry standards. The time in which any bearings may be expected to fail shall not be less than 25,000 hours under maximum dynamic loads. Provisions shall be provided for periodic lubrication. The height of the antenna pedestal subassembly shall provide for a minimum clearance of 6 inches between the base level of the subassembly and the lowest part of the moving antenna assembly. Attachment points for a minimum of four tie-downs shall be included on the subassembly, located such that attachment of tie-downs will not obstruct operation of the antenna. The contractor shall furnish a weatherproof reusable packing/shipping container for the antenna pedestal subassembly. The antenna pedestal, or local control box (if configured with such), shall include a space to mount drive amplifier of 15” x 6” x 6”, with AC power switched by the auxiliary power control at the ACU. Two pairs of RF connectors to the exterior are also required in conjunction. See section 3.3.1.11.

3.2.1.5 Pedestal Cabling

Unless otherwise specified, pedestal cabling between sub-assemblies, such as the pedestal and feed enclosure, shall be connectorized to facilitate disassembly and reassembly. The cabling supplying electrical power to the pedestal equipment shall be terminated with weather-proofed, harsh environment type field replaceable connectors which facilitate disconnection and reconnection. The installation of internal pedestal wiring may be made by connectorized or terminal strip type wiring techniques. All subassemblies that come apart for packing/shipping shall have connectorized cabling. The installation of cabling external to the pedestal assembly shall be accomplished in a manner that will prevent cable damage due to antenna system motion. A strain relief method, e.g., woven grip strain relief, or equivalent, shall be employed for each applicable cable. RF cabling shall be of the lowest practical RF loss type with protective jacket. Cables shall be ruggedized and not to exceed 0.4 inches in diameter. Cables provided shall be as specified; or if not specified, shall satisfy the environmental and performance requirements specified. All pedestal control circuits shall be designed to allow 200 feet of cable between the outdoor antenna system and the indoor control equipment. All control cables shall be supplied with the system, and shall consist of pre-connectored sets not to exceed 100 feet long, with provisions such that the antenna can be operated using one of the sets alone, or all sets connected together to form a set 200 feet long. The contractor shall provide a weatherproof reusable packing/shipping container for the antenna cables.
