Demystifying MIDS:MIDS Standards and Specifications

MIDS Specification: STANAG 4175 Provides a detailed technical specification for MIDS terminals. STANAG 4175 is the governing document for MIDS terminal design.

MIDS System Segment Specification (SSS) Establishes overall performance and qualification requirements for the

MIDS-LVT.

System/Segment Hardware ICD Purpose: Specify mechanical, electrical and cooling interfaces between

MIDS Hosts and the MIDS System equipment.
