Duro Product Summary

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

Swift Navigation, in partnership with Carnegie Robotics, introduces 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 devices require precise navigation—especially those that perform critical functions. Swift Navigation’s Piksi Multi module within Duro utilizes real-time kinematics (RTK) technology, providing location solutions that are 100 times more accurate than traditional GPS.

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 much faster system start times, as well as faster reacquisition, critical to robotic systems.

Field Upgradeable
Swift Navigation and Carnegie Robotics have partnered to create a product that offers a technology development platform that can easily be software-upgraded to leverage Swift Navigation’s and Carnegie Robotics’ future intellectual property and technology.

Leverages Piksi Multi
Multiple signal bands enable fast convergence times and multiple satellite constellations enhance availability. Piksi Multi supports GPS L1/L2 and GLONASS G1/G2 for RTK measurements and positioning and SBAS for robust sub-meter positioning in non-RTK mode. Other constellations such as BeiDou, and Galileo are planned to be rolled out in the near future. No additional upgrade charges for constellation upgrades.

7 Currently a Beta Feature. While this feature is currently available to end-customers and can be used, it still has a Beta developmental status. This implies that while the feature will work, there is a potential for unknown firmware bugs which Swift Navigation is or isn't aware of. Customers using this feature need to note that user documentation for it may not be fully complete and Swift Navigation is not liable for customers intending to use a Beta feature in a final production environment.
