Currently Available Drafts of this Important Standard Reveal Significant Changes For nearly 50 years, MIL‑STD‑461...

Electromagnetic Compatibility Assessment of Wireless Emissions in Shipboard Spaces

Electromagnetic compatibility of wireless communications and sensor networks with mission critical electronic equipment is assessed for below-deck spaces on ships and submarines. With intentional wireless emission of radio-frequency (RF) energy into the reverberant spaces, it is necessary to measure and characterize the statistical electromagnetic environment (EME) and to predict maximum electric field strengths to a specified confidence level.

Current Harmonics Testing: MIL-STD-1399 Section 300B versus MIL-STD-461F

The extensive use of power electronics on vessels and offshore installations, especially on electric propulsion ships, has had a substantial impact on the power quality of the power distribution system. This article discusses the effects of current harmonic distortion created by commercial uninterruptible power supplies (UPS) being deployed in Naval shipboard applications.
