The ISLET project delivers two distinct solutions tailored to fundamentally different navigation environments, both enhanced through the use of Galileo High Accuracy Service (HAS) corrections.
The first solution is designed for maritime navigation, targeting applications that demand high accuracy . For this environment, ISLET Receiver-P offers two alternatives: one main mode based on Precise Point Positioning (PPP) and another Standard Point Positioning (SPP) mode as fallback. Under PPP conditions, the receiver is expected to reach maritime navigation accuracies of up to 0.2 m (95%) in horizontal positioning and 0.4 m (95%) in vertical positioning, leveraging advanced PPP algorithms. This solution for maritime applications will be based on a modular approach, in which the product can easily evolve in the future to include new features and capabilities. The main components of ISLET receiver-P will be a GNSS antenna, the GMV OEM GNSS receiver, the FLIR TransponderTech Navigator and a control and display unit (“CDU”).
The devices mentioned have been successfully tested in previous projects, building on GMV and FLIR’s experience with shipborne receivers. These technologies are widely trusted by users in maritime navigation.
The second solution targets inland waterways, including navigation along rivers and channels, targeting applications with some degree of automation. For this scenario, ISLET provides an operational mode based on HAS corrections and Standard Point Positioning (SPP). This approach targets positioning accuracy of up to 1 m (95%), enhancing reliable and efficient navigation in constrained inland environments. Also, the inland waterways solution incorporates an advanced integrity algorithm, known as IBPL, ensuring safety and reliability in the provided solution. In this case, the modular solution includes GMV OEM GNSS receiver, assembled inside a GMV enclosure and connected to TRESCO ECDIS for displaying information.
Both solutions are based on a multi-constellation approach combining Galileo and GPS, multi-frequency reception and incorporate Galileo OSNMA to enhance resilience against spoofing.
