Intelligent signal conditioner
Satellite navigation services have become indispensable across many areas of daily life. In addition to conventional navigation applications, safety-critical services and critical infrastructure in particular depend on precise positioning, navigation and timing (PNT). At the same time, a significant increase in jamming and spoofing signals has been observed worldwide in recent years. These can either disrupt the reception of Global Navigation Satellite Systems (GNSS) or deliberately falsify it through manipulated signals.
To address this, we have developed the InVo signal conditioner. The antenna system reliably detects and suppresses jamming and spoofing signals on multiple levels. A particular advantage is the ease of implementation: existing systems can be protected effectively simply by replacing the antenna, without the need for complex or costly structural modifications. For applications with specific requirements, an integrated multi-antenna receiver is also available. InVo can therefore support high-precision positioning applications. An additional interface can also provide information on detected interference signals. The system has already proven successful in flight tests with real jamming signals. Building on our expertise, the company Lange-Electronic is now developing the technology into a commercial product.
