Egnos will augment both gps and galileo in the future (in egnos v3) using l1 and l5 frequencies Egnos performances are usually described in. The egnos safety of life service (sol) consists of an augmentation signal to the global positioning system (gps) standard positioning service (sps) intended for most transport safety critical applications The target application domains are, thus, aviation, maritime, railway and road where degradation in the navigation system performance without a notice within the specified time to alert. European geostationary navigation overlay service (egnos) is designed to provide in europe the regional augmentation to gps and glonass systems The main objective of the implementation such an augmentation is to improve the performance of existing satellite positioning systems in the context of accuracy, integrity, availability, and continuity.
It is intended to be of use for air navigation service providers (ansps), receiver manufacturers, equipment integrators. Initially deployed for safety of life navigation services in aviation, egnos has expanded its applications to emerging domains such as unmanned. These are complex organisational structures which, apart from positioning or transmission of navigation information, employ a comprehensive approach to safety of sea basins close to the shore.
