GIDAS – GNSS Interference and Analysis System

The growing number of applications and users is making it increasingly important to take into account not only the possibilities but also the vulnerabilities and risks of satellite-based positioning.

Currently, many users are unaware of the potential threats and impacts.

Over the last few years, GNSS applications have increasingly become the target of jamming (weakening satellite signals) or spoofing (falsifying signals) attacks. Interference can cause significant economic as well as material damage as interference signals can significantly impair GNSS operations.

This can lead to degraded position accuracies or to a total failure of the positioning.

GIDAS monitors the GNSS frequency bands and reliably detects, classifies and locates any intentional and unintentional sources of interference. The system consists of a high-performance data processing unit including an antenna and RF front-end as well as a sophisticated software solution.

GIDAS is not only able to monitor GNSS-based position, velocity and time solutions but also monitors the signal received and baseband processing.

MCGS - Multipurpose Cooperative GNSS Service

Independent mass market receivers normally achieve a positioning accuracy of a few meters. In order to produce significantly higher accuracies, considerably more expensive multifrequency devices must be used.

With MCGS, any type of GNSS receiver achieves higher positioning accuracy in real time, avoiding the need to invest in high-end devices or expensive infrastructure.

MCGS combines in real time the best processing approaches with the principles of collaborative client data processing and cloud computing. It provides this advanced GNSS data by supplementing the client measurements with precise a priori data available on the server side using satellite clocks and tracks, local meteorological parameters, ionosphere parameters, data from the existing nearby GNSS infrastructures and data from geographic information systems (GIS). As a result, MCGS selects the best algorithm for any type of client device (from smartphones to geodetic devices), guaranteeing the most accurate navigation solution.

MCGS is a multi-purpose service that supports any type of user application, from site-specific services with mass-labeled devices to high-precision systems based on the most advanced receivers.

It improves positioning accuracy and quality for mass market recipients or location-based service providers by leveraging the benefits of collaborative data processing.

SARONTAR – Emergency Response Coordination System

SARONTAR is an operational control system with team-live tracking for an effective and coordinated approach to alpine search and rescue missions.

In the event of natural disasters (avalanches, landslides, floods) or accidents in alpine regions, time is of the essence. Coordinated assistance needs to be provided for the persons concerned as quickly and efficiently as possible. SARONTAR focuses on precisely this requirement by offering rapid and coordinated organizational support for alpine emergencies.

With the help of satellite-based positioning and communications, search and rescue teams at remote locations are coordinated by a central SAR control center, which supports them in their tasks by providing them with position-dependent information. Different geo-information, remote sensing and communication methods are used for this purpose.

All position data, incoming messages and warnings are processed by SARONTAR. This consolidated information is presented graphically on the mobile devices and at the mission control center.
SARONTAR is being used by the Styrian State Warning Center (Austria), for example, for alpine search and rescue missions.
