Duro Product Summary

Ruggedized Multi-Band, Multi-Constellation Centimeter-Accurate GNSS

Swift Navigation, in partnership with Carnegie Robotics, offers Duro—an enclosed version of the Piksi® Multi dual-frequency RTK receiver. Built for the outdoors, Duro combines centimeter-accurate positioning with military ruggedness at a breakthrough price.

Built to Be Tough
Duro leverages design principles typically used in military hardware and results in an easy-to-deploy sensor, protected against weather, moisture, vibration, dust, water immersion and unexpected circumstances that can occur in long-term, outdoor employments.

Easy Integration
Duro’s M12 connectors are sealed and industry standard, which balances ruggedization perfectly with user-friendliness. No external sealing is required to deploy in even the harshest conditions. The exposed interfaces support varied use cases without integration headaches.

Centimeter-Level Accuracy
Autonomous platforms require precise positioning—especially those that perform critical functions. Swift Navigation’s Piksi Multi receiver within Duro utilizes real-time kinematics (RTK) technology, providing location solutions that are 100 times more accurate than traditional GNSS solutions.

Fast Convergence Times
Multiple signal bands enable fast convergence times to high-precision mode. Single band RTK systems converge in minutes, while Piksi Multi converges to a high-precision solution within seconds. This allows for faster time to first fix (TTFF), as well as faster reacquisition times which are critical in high dynamic autonomous applications within a variety of environments.

Leverages Piksi Multi
Multiple signal bands enable fast convergence times and multiple satellite constellations enhance availability. Piksi Multi supports GPS L1/L2, GLONASS G1/G2, BeiDou B1/B2 and Galileo E1/E5b for RTK measurements and positioning along with SBAS for robust sub-meter positioning in non-RTK mode. No additional upgrade charges for constellation upgrades.
