Seatag GEO
The SeaTag-GEO is a pop-up satellite archival tag (PSAT) designed for high-precision migratory tracking to produce more accurate horizontal tracks than light-only geolocation. It shares the same compact form factor as the SeaTag-LOT and supports both archival pop-up deployments and real-time tracking with daily summaries, offering flexibility for a wide range of study designs.
