Navy awards IAI follow-on contract for using Time Domain Reflectometry (TDR) for wire fault detection in the Electrostatically Supported Gyro Navigator (ESGN)

Slip ring assemblies are crucial components for many gimbaled platforms and are used for transferring digital, analog and clock signals, and power between the gimbals. Slip rings are very reliable, but can also cause operational and maintenance problems due to wearing out of mechanical parts, and cross-coupling caused by moisture. This causes signal glitches, resulting in intermittent electrical problems. Locating the problem sites is difficult on the stable platform of the Electrostatically Supported Gyro Navigator (ESGN), which is planned to be operational until at least 2024 and is experiencing age and wear related electrical problems. The large number of interconnections requires hours of installation, inspection and maintenance and increases the probability of failures. To address this, IAI and its collaborator, the Boeing Corporation, will evaluate the use Time Domain Reflectometry (TDR) to detect and locate hard-to-isolate and intermittent faults in the ESGN. The evaluation will be performed with WireCheckTM, IAI’s high performance TDR instrument. WireCheck has the potential to quickly and precisely detect and locate the most troublesome wiring faults for slip-rings, wiring, connectors, motors, and inductosyns. WireCheck will allow technicians to accurately locate faults with sub-inch accuracy without accessing the stable platform. This will decreasing the chance of secondary damage, reduce the unnecessary replacement of parts, and increase the chance of mission successs.
