The use of a modular open systems approach (MOSA) will benefit the effort to integrate alternative position, navigation, and timing (PNT) technologies into platforms.

Analysis of the latest technologies being developed by avionics OEMs for the emerging eVTOL market.

From a design and engineering perspective, there are many moving parts to consider and combine in order to arrive at a position, navigation, and timing (PNT) truth. In addition, solutions must be easy to integrate into the available space on existing platforms, whether they are unmanned aerial systems (UASs) or other aircraft, ground-based operations, or systems at sea.

A panel on CMOSS at a U.S. Army Technical Exchange Meeting held earlier this year provided details on new developments underway and areas in which the Army is looking to industry for help in taking the suite of standards from prototype to deployment.

Newer on-vehicle integrated networks will be composed of heterogeneous networks in the form of software and equipment from multiple commercial vendors.

Bringing the benefits of multicore processors to safety-critical systems is challenging. Read how Curtiss-Wright and Green Hills Software are up to the challenge.

Rick Hearn explains how the key computing elements of an avionics system must all be designed with safety in mind and endure stringent testing to prove they can meet the required Design Assurance Level (DAL).

Given its complexity and the critical applications for which it is designed, embedded avionics software must undergo a rigorous approval and testing process before it can be approved as airworthy.
