Permanent Navigation and Surveillance for Autonomous Vehicles (NeSIVA)

在各种应用中对全球导航卫星系统（GNSS）定位、导航和定时系统的依赖，促使科学界研究在全世界寻找可靠和有效替代品的可能性。这是因为在许多密集的城市和室内环境中，GNSS没有足够的功率穿透建筑物墙壁，信号不断丢失，并且GNSS很容易被简单的发射机干扰。ÉTS的空间技术、嵌入式系统、导航和航空电子实验室（LASSENA）的研究工作已经确定了一种非常有前途的技术作为障碍物定位和检测的来源，利用机会信号（SoOP）。事实上，低海拔卫星（LEO）以及3G/4G/5G/6 G发射机发出的信号（LEO的数量在地球仪周围呈指数级增长）可用于提供PNT和入侵者检测数据（PNS-D），这些数据对自主空中和地面车辆至关重要。原则上，具有用于民用和军用自动驾驶车辆的LEO-SoOP的弹性和鲁棒PNT系统，实现多类型4G/LTE/LEO-SoOP融合，提供新一代监视和导航，换句话说，NeSIVA将重塑导航。应该注意的是，SoOP技术以被动和非合作模式运行，并在当前系统受到网络攻击时提供必要的弹性。只有少数研究机构（ICU，弗吉尼亚理工大学...）已经发表了关于SoOP的工作，工业合作伙伴和魁北克对这一具有破坏性和非常有前途的技术采取全球立场的大门是敞开的，由于对基于非GNSS SoOP的PNT技术的高度关注，该技术有可能在本十年结束时成为标准。

The reliance on Global Navigation Satellite System (GNSS) Positioning, Navigation and Timing (PNT) systems in various applications is leading scientific communities to investigate the possibility of reliable and efficient alternatives worldwide. And that's because in many dense urban and indoor environments, GNSS doesn't have enough power to penetrate building walls with constant signal loss, and GNSS can be easily jammed with a simple transmitter.The research work of the Laboratory of Space Technologies, Embedded Systems, Navigation and Avionics (LASSENA) of ÉTS has identified a very promising technology as a source of positioning and detection of obstacles, by the exploitation of Signals of Opportunity ( SoOP). Indeed, the signals emitted by low-elevation satellites (LEO), the number of which is growing exponentially around the globe, as well as by 3G/4G/5G/6G transmitters, can be used to provide PNT and intruder Detection data (PNS-D) essential for autonomous air and ground vehicles.For this, NeSIVA will develop an intelligent universal SDR-based SoOP receiver, in principle with resilient and robust PNT systems with LEO-SoOP for civil and military autonomous vehicles, realizing a multi-type 4G/LTE/LEO-SoOP fusion, offering a new generation of surveillance and navigation, in other words, NeSIVA will reinvent navigation.It should be noted that the SoOP technology operates in passive and non-cooperative mode and provides the necessary resilience in the event of a cyber-attack on current systems. Only a few research institutes (ICU, Virginia Tech...) have published work on SoOP, and the door is open for industrial partners and Quebec to take a global position on this disruptive and very promising technology which risks becoming a standard at the end of this decade due to the high attention in non-GNSS SoOP-based PNT technologies.
