- Why PASI
GLIDE is a positioning algorithm that provides superior pass to pass accuracy (over 15 minute durations) in environments where a differential signal is not available. GLIDE works globally, independent of correction signals such as WAAS or EGNOS, so it provides a stable signal for customers in Eastern Europe, Australia and South America.
Additionally, GLIDE is focused on providing excellent service in areas of high ionospheric disturbance.
On the scale of correction source accuracy, GLIDE is positioned above Autonomous pass to pass but below differential solutions such as WAAS and EGNOS.
GLIDE absolute accuracy with the GPS 6500 is improved over the GPS 6000's GLIDE operation because the GPS 6500 has dual frequency capabilities.
