The ISLET navigation solutions were conceived to support a wide range of applications that require a high level of accuracy achievable through the use of Galileo HAS corrections.
For maritime applications, the hydrographic use case focuses on the collection, management, and analysis of data related to oceans and seas. In particular, bathymetry plays a key role, as it involves depth measurements and it is essential for mapping underwater topography. This information is critical to ensure safe navigation by providing precise nautical charts that support skippers, captains and pilots.
Another important maritime application is the placement of buoyage and other aids to navigation (AtoN). This includes the planning, deployment and maintenance of buoys, beacons and navigational markers that guide vessels safely through waterways, ensuring that channels and hazards are clearly and accurately indicated.
Hydrography was identified as a suitable use case for ISLET maritime operational management , adding not just value in terms of high accuracy , but also because alternative positioning technologies may be unavailable or unreliable in certain conditions. For instance, DGPS and RTK solutions become ineffective in offshore environments, where the distance from coastlines and reference stations increases significantly or when internet connection is unavailable in remote regions while Galileo HAS Signal in Space remains active.
For inland waterways, applications are mainly focused on operations in narrow and constrained channels, with the aim of reducing fairway width and close ship encounters, where Track Guidance Assistant for Inland Navigation (TGAIN) may not be sufficient. This becomes of special interest in the case of autonomous vessels.
Note that this does not mean that other Maritime and IWW applications requesting highly accurate precise positioning are automatically discarded for both ISLET receivers.
