ATC Systems
Abstract
Landing System Upgrade Program (LSUP) consists of life cycle extension (LCE ) upgrades to the AN/SPN-35C Precision Approach Radar (PAR), AN/SPN-41B (Instrument Control Landing Systems (ICLS)) and AN/SPN-46 Automatic Carrier Landing Systems (ACLS) systems which support Air Traffic Control (ATC) operations on board CVN, LHA, or LHD-class ships. This effort includes numerous commercial off-the-shelf (COTS) component refresh updates which are urgently needed to sustain the operational viability of these Naval ATC systems in order to support Fleet air operations for at least the next 15 years until the next generation ATC system is fully implemented. This COTS refresh will include analysis and upgrade of key system components that are critical to overall system operation but have become increasingly difficult to maintain over the past few years. Recent adjustments in the direction and scope of Naval ATC systems have necessitated a re-evaluation of the long-term viability and sustainability of the current Fleet ATC equipment. The result is a renewed appreciation for the value these ATC systems provide to the Fleet based on the comparative relationship between sustainment costs and overall system reliability. This COTS Refresh is expected to include analysis and upgrade of the following components: Gearbox Stepper Motors, Logic Controller Assembly, Power Supplies, Roll Encoder Assembly, Micro Electro Mechanical Systems (MEMs) Assembly, Fiber Optic Media Converters, Touchscreen Display Assembly, Communication Assembly, Maintenance Test Drawer Assembly, and Radio Frequency RF Monitor Assembly, and upgrades of the Transmitters and Radomes are expected to ensure accurate and continuous functionality of the AN/SPN-41B system. Additionally, COTS refreshes will be necessary to mitigate obsolescence concerns for power supplies and various circuit card assemblies. Recent changes to the Navy's Precision Approach and Landing Capability (PALC) requirements have necessitated Life Cycle Extension (LCE) upgrades to legacy landing systems, AN/SPN-35, AN/SPN-41 and AN/SPN-46. This is a new start in FY2015.
