Overview
Medha’s Mission Management and Display Computer (MMDC) is a high-performance processing and display system built on a compact 3U OpenVPX architecture. Its processor-mezzanine design provides flexibility for future processing upgrades while supporting space-constrained, mission-critical applications.
The MMDC integrates high-integrity graphics processing, ARINC 818 Version 2 video interfaces and an add-on I/O module for expanded interface requirements. An optional ARINC 664-compliant AFDX End System enables connectivity to aircraft data networks.
Designed, developed and manufactured in-house by Medha, the MMDC can be customised for complex mission-management applications across rotary-wing and fixed-wing aircraft.
