GNSS網絡安全和反欺騙產品

隨著PNT（位置、導航、定時）各個方面對GPS/GNSS的依賴持續增長，干擾和欺騙攻擊的數量和復雜程度也在增加。使用相當低技術的欺騙器和開源軟件的網絡恐怖分子可以輕松部署提供虛假GPS/GNSS信號的欺騙器，并可以攻擊和破壞依賴GNSS計時或關鍵基礎設施（如電信網絡、金融機構或發電廠。無論是在國家層面，例如俄羅斯在俄羅斯總統周圍操縱GPS信號，還是僅討論2020年記錄的數千次GPS欺騙攻擊中的一部分，欺騙案例都在媒體中得到充分記錄。
AccuBeat認識到并了解這些威脅，開發并獲得專利的產品和解決方案可保護您最關鍵的資產、網絡、平臺和基礎設施，并確保即使在GPS/GNSS被拒絕的環境中也能持續安全地運行。這些解決方案包括我們獨特的專利Time FireWall™ - 一種即插即用的解決方案，旨在保護您的舊設備，無需更換現有設備。AccuBeat還提供AR50一種便攜式定時傳播案例，用于干擾或欺騙阻止與GPS/GNSS信號的初始連接的情況，以及一個可選的塢站,可在中心位置存儲和監控多達12個案例。
AS133系列產品是 AccuBeat的新一代多功能銣頻率標準，結合了我們專有的反欺騙軟件。AS133 系列產品包括幾個不同的子版本，是當今可用的最小的原子標準之一，其準確性和穩定性源自游離銣原子中發生的量子躍遷。該裝置采用獨特的先進技術，可以在不犧牲性能的情況下減小裝置的尺寸。
AS133 由獨特的 DFLL（數字頻率鎖定環）組成，其中高性能石英晶體振蕩器使用嵌入式微處理器和特殊的專利算法鎖定到銣原子線。該算法針對外部干擾優化了性能，提高了溫度穩定性，并實現了非常精細的數字頻率控制。
