About
LEORIX is a multi-constellation single-frequency GNSS receiver. It features GPS and GALILEO reception, providing excellent on-board real-time navigation with an accuracy of below one meter.
Advanced Kalman filtering and single-frequency ionospheric correction enable high on-board navigation performance. A flexible acquisition and tracking concept provides single frequency signal processing of up to 12 satellites.
LEORIX’s selective RF-filter and low-noise amplifier significantly improve performance, while its accurate force model-based orbit propagator ensures precise navigation in challenging environments.
LEORIX’s configurable data rate per measurement type and autonomous start-mode determination minimize time-to-first-fix, while its powerful parameter interface supports changes in standby and operational mode.
