Initially released by Swift Navigation in early 2020, then was bought by Carnegie Robotics in fall 2024,
Duro™ is a ruggedized, high-performance and low-cost GNSS receiver with Real Time Kinematics (RTK) technology for a centimeter-level positioning accuracy. GNSS multi-band and multi-constellation support enable Duro to offer fast RTK convergence times and high position availability.
Duro uses the Piski Multi multi-band, multi-constellation GNSS receiver in a ruggedized enclosure. This page will contain information about both the Duro and Piksi Multi - as far as I can tell, there is little inherently unique about the Duro compared to the Piksi Multi mounted on the evaluation board that Swift Navigation also sold it on.
