GIDAS – The GNSS quality assurance for every need
Benefit from our versatile solutions for GNSS interference detection, alerts, localization, and statistical reports
Why GNSS Quality Assurance?
Global Navigation Satellite Systems (GNSS) positioning and timing services form the backbone of many applications and markets. Civilian GNSS services are free of charge and globally available but insufficiently protected against unintentional and even intentional disturbances. OHB Austria has researched for more than 20 years how to provide means to monitor and augment the GNSS services with GNSS quality assurance. For many applications, it’s not only precision that matters, but predominantly integrity too! Our knowledge and experience in GNSS quality assurance are available in many different forms in our GIDAS product family.

Jamming & Spoofing
GNSS is globally and freely available, but vulnerable to many threats. The signals transmitted from GNSS satellites orbiting the Earth at approximately 20.000 km altitude above the Earth’s surface are very weak, and the transmission power of a 100W light bulb (depending on the constellation and satellite generation) is very weak. The signals are received on the Earth’s surface with power below the thermal noise floor. These weak signals can be disturbed or degraded by many sources.
The first step in protecting your GNSS-dependent applications or platforms is to monitor the GNSS signal health on-location in real time. While systems such as space-based augmentation systems (SBAS) or country-wide monitoring systems are typically designed to monitor the constellation health status (orbit-, satellite-clock-, uplink-errors), local interference or local anomalies are not visible. Especially for safety-critical applications, it is vital to monitor the GNSS signals and services as close to the application as possible.
