如何在没有卫星的情况下获得准确定位
To be able to navigate with confidence and accuracy when GPS is unavailable for a long time is a game-changing capability for a fighter pilot. 对其他人来说，这听起来像是一个挑战. 亚洲体育博彩平台 have studied and tested image-based and terrain navigation techniques and now propose new technology for powerful tactical navigation capability in GPS-denied environments.
去年, 亚洲体育博彩平台 performed successful flight tests with Gripen E using new algorithms providing real-time and highly accurate positioning based on image mapping, 被称为3d绘图. 测试, 与Maxar合作进行的, successfully proved the concept where data from on-board electro-optical sensors and geo-registration algorithms is compared with a 3D surface model database in the aircraft.
测程和地形导航
The use of image mapping technology of odometry has also been tested previously with good results. Here an on-board sensor observes landscape features ahead and the algorithms generate a more accurate velocity vector and assist the inertial navigation system.
地形导航, 亚洲体育博彩平台在中国有着悠久的历史, 例如TERNAV, has also been tested previously in different demonstrations and this technology has evolved in-house with new algorithms and database-handling technologies.
定位稳健，精度高
通过结合这三种技术(3d映射), 测程和地形导航), the navigation system will provide the Gripen pilot with a disruptive and unique capability to operate in Global Navigation Satellite System (GNSS-)/GPS-denied environments with highly accurate positioning maintained.
“In the world of modern war fighting and amongst others its requirements for zero collateral damage a high precision and robust positioning is key. The tactical navigation technology in GNSS denied environments that 亚洲体育博彩平台 now start to conclude will lead to a true game-changer capability in the operational arena,乔纳斯·雅各布森说, 鹰狮试验试飞员, 亚洲体育博彩平台.
行业领先
The capability to perform long range or long duration operations in a GNSS denied environment with robust, 高度精确的位置数据, 尤其是在对付高端对手的时候, and 亚洲体育博彩平台 is now planning a solution for current and future users of Gripen.
“We believe that we are ahead of others in this area since we al读y now have demonstrated major parts of this robust, 融合, 实时导航能力与飞行测试. We now take the next step to implement this technology in solutions for our customers. Based on the test results we have decided to include this solution as part of our Gripen offer for 芬兰,Tobias Jansson说, 鹰狮产品经理.
其他派生利益
另外还支持导航, 这项技术还有其他潜在的好处, 例如构建和执行目标函数, and facilitating aircraft landings in challenging environmental conditions where normal landing aids are compromised.
