MIAR (Making I-CNSS a Reality)

LDACS, a digital broadband radio link, offers a secure, scalable, and spectrum-efficient data connection between aircraft and terrestrial infrastructure, similar to cellular telephony. What sets LDACS apart is its integrated navigation and surveillance capabilities, making it an attractive solution for the aviation industry's communication, navigation, and surveillance (CNS) needs.

The MIAR project's primary objective is to demonstrate how LDACS can enable optimized separation between aircraft in real-time, enhancing safety and efficiency. Additionally, the project aims to showcase the use of multiple non-GNSS (Global Navigation Satellite System) technologies to provide a comprehensive integrated navigation solution, which can provide safe navigation even under conditions of GNSS jamming, spoofing, and other forms of interference.

Rohde & Schwarz, a leading provider of communications and information security solutions, developed the LDACS demonstrator devices in close collaboration with the German Aerospace Center (DLR) and DFS (Deutsche Flugsicherung GmbH). Successful flight tests conducted with a DLR test aircraft have validated the effectiveness and potential of LDACS in real-world scenarios.

Building on this success, Rohde & Schwarz is now focusing on implementing new, miniaturized demonstrators for both ground and avionics applications. These advancements will further enhance the capabilities and versatility of LDACS, paving the way for its future integration into the aviation industry.

LDACS has the potential to revolutionize aircraft communication and navigation, offering a secure, scalable, and spectrum-efficient data link. With its integrated navigation and surveillance capabilities, LDACS presents a compelling solution for the aviation sector's CNS requirements. The ongoing development and implementation of avionic LDACS demonstrator devices by Rohde & Schwarz, in collaboration with DLR, Frequentis, and DFS Deutsche Flugsicherung GmbH, represents a significant step forward in the evolution of aviation communication and navigation systems.
