Carnegie Robotics and Swift Navigation have unveiled a new GNSS receiver at Xponential 2017 in Dallas, Texas.
Duro is an enclosed, ruggedised, multiband, multiconstellation GNSS receiver with centimetre accuracy. It can be fitted onto any type of ground vehicle.
The Piksi multi module within Duro uses real-time kinematics (RTK) technology, providing location solutions that are claimed to be 100 times more accurate than traditional GPS. It is larger than standard GPS receivers, as it is uses a dual frequency L1/L2 systen, and measures the carrier phase.
The system features an on-board MEMS IMU and magnetometer as well as on-board data logging up to 32 GB. No external enclosure is needed due to the casing having an IP67 environmental certification.
Successful testing has been carried out on vibration, thermal, electromagnetic interference, and shock resistance with all the inputs and outputs being exercised. The unit can withstand dust, heat, and be submersed to depths of 1 m.
Speaking to Jane's , Chris Osterwood, Senior Engineer at Carnegie Robotics, explained that the is "a wrap around Piksi multi, so it has all the precision and functionality of the Piksi but in this rugged enclosure which removes a lot of the burden in integration. The GPS and antenna connection map directly with the top grill, you can also mount the antenna offboard in a bracket. It screws without [the need for] any tools so it lets you move the antenna to any other location on a vehicle. The great thing about Duro is because of its wide temperature range [-40 to 75° Celsius] and vibration capability, you can basically put it wherever you want on any vehicle. You don't need to provide it with saw shielding or anything like that. You can put this on the roof [of a vehicle] with the antenna mounted right to it and run two cables to it and you are done."
