uAvionix最近完成了其SkyLine指揮與控製(C2)管理服務的複雜演示，其中多個無人駕駛飛機係統(UAS)從基於雲的C2平台控製，而每架飛機都通過多個同時連接到多個地麵無線電的多個鏈路連接到SkyLine。該演示是與俄克拉何馬州Chocktaw Nation (CNO) UAS測試中心協調進行的，該中心是FAA Beyond的主要參與者。避免丟失鏈路場景對於超視距(BVLOS)操作至關重要。每種無線電和頻率都有優缺點，這取決於作業的地理位置和海拔高度。uAvionix解決方案利用路徑分集和鏈路分集，通過在無線電類型之間實現無縫無損切換，重點關注防止鏈路丟失情況。當射頻信息到達目的地有多條物理路徑時，就存在路徑分集。這可以通過飛機上的多個無線電或地麵上的多個無線電來實現。演示涉及飛機上的uAvionix microLink ISM無線電，提供2x2多輸入多輸出(MIMO)分集，有效地將2個無線電合為一體，有兩個獨立的天線，每個天線連接到地麵上的多個天站ISM無線電，每個天線本身就是一個2X2-MIMO。路徑多樣性為任何給定鏈路通過多個物理路徑到達目的地提供了最佳機會。當存在不同的無線電或頻率時，存在鏈路分集。 For this demonstration, in addition to the ISM frequency microLink/skyStation radios, the uAvionix muLTElink provided LTE connectivity by its own internal 2X2 LTE MIMO. Therefore, on the aircraft, both path diversity and link diversity exist because the data can reach its destination through different radios (and frequencies) as well as different physical pathways from antenna to antenna. Combining both link diversity and path diversity creates a self-healing, deterministic, and low latency network incredibly resistant to interference or jamming due to the redundancy of pathways for the data to be transmitted and received. Managing this complexity is the SkyLine C2 management platform, which provides the operators with real-time statistics of each radio link, and allows either automatic or manual “roaming” from radio to radio, either in the air or on the ground. “The Choctaw Nation of Oklahoma and the unique Emerging Aviation Technology Center (EATC) site with its vast diverse terrain are a perfect location to demonstrate the muLTElink and SkyLine capabilities,” said Marc Hartman, Manager of Aviation Operations with CNO, “With existing gaps in cellular coverage it provides a real-world environment to showcase the unique ability of muLTElink and SkyLine cloud service to provide seamless command and control of an aircraft in real-world environment”. In addition to automated C2 management, uAvionix also used SkyLine to demonstrate an integrated detect & avoid (DAA) capability from terrestrial sensors, including the CNO Detect HARRIER™ terrestrial primary radar information and several uAvionix pingStation3 ADS-B receivers to provide a complete picture of cooperative and non-cooperative aircraft in the entire airspace. “The capability of presenting integrated radar and ADS-B data into a managed C2 solution ultimately utilizing uAvionix C-band radios is a major contributor to our planned BVLOS operations here at the Choctaw Nation,” stated Hartman.
