Polynesian Exploration Inc. has launched its high-accuracy navigation system for demanding applications such as autonomous driving and unmanned aerial vehicles (UAVs). Polynesian Exploration is a navigation startup founded by a group of navigation-industry veterans in Silicon Valley in October 2016. The navigation system is designed to fully utilize the advantages of both GNSS and inertial navigation systems (INS) to provide centimeter-level position and velocity accuracy with dual frequency real-time kinematic, together with accurate attitude information (roll, pitch and heading). The system provides superior short-term stability against satellite signal outages and highly accurate heading whether the system is static or moving, Polynesian Exploration said. The rugged and waterproof system will be ready for shipment starting July 1. Polynesian Exploration described the demand for high-accuracy GNSS/INS solutions this way: By the year 2020, four GNSS are expected to be fully operational, which are GPS, GLONASS, Galileo and BeiDou. The abundance of measurements from multiple constellations around the world will enable unprecedented improvements in the accuracy, continuity and integrity of GNSS navigation systems. Although GNSS signals have grown to become ubiquitous, all radio-navigation systems are subject to radio frequency interference, short signal blockages and severe multipath errors in certain environments (such as urban canyons). INS can potentially mitigate integrity and continuity risks caused by those issues to a certain degree. Additionally, INS is able to compute and output user’s position, velocity and attitude at high frequencies. Reporting information to users at a high-frequency is essential for many vehicle control applications, such as self-driving cars, UAV flight stability or autonomous landing. We design our navigation systems with various performances depending on user demands, which include, but are not limited to, up to 400-Hz position, velocity, attitude outputs and meters to center-meter level position accuracy. They can also be operational in all weather conditions and will be available globally. Additionally, we are able to integrate special sensors for each unique application as requested by our customers. We are driven by customer satisfaction and strive to offer the best experience for our customers.
