The new Yuneec H520E hexacopter was developed for commercial drone applications and provides police, fire brigades, search and rescue ground teams, inspectors and surveying teams with useful and effective results. The Yuneec H520E is a flexible, robust and powerful UAV platform that can be adapted to individual requirements and thus enables a variety of industry-specific applications. Long time flight capability and high-quality camera options with embedded GPS data allow an area to be recorded efficiently and with maximum precision. The interference-free precision compass enables flying even in difficult-to-fly environments. The H520E RTK provides survey-grade centimeter-level accuracy with CORS network connectivity built-in to the DataPilot interface. The H520E RTK also features PPK compatibility - making it a powerful took for all types of inspection and survey work. The H520E RTK module is one of the smallest all-constellation multi-frequency high precision RTK and heading modules on the market. The RTK module is targeted for use in robots/UAVs and intelligent driving applications - providing reliable centimeter-level accuracy and a high accuracy heading output at high update rates. The RTK module employs a single UC4C0 (432 channel tracking) baseband chip with internal RF front-end in a single-sided SMD package - achieving a very small size (30x40 mm). It can simultaneously track GPS L1/L2 + BDS B1/B2I + GLONASS L1/L2+Galileo E1/E5b+QZSS. The H520E RTK Module adopts new-generation “UGypsophila” RTK processing technology and takes advantage of high-performance data sharing capability and the extremely simplified operating system within the Nebulas-II GNSS SoC chip. It uses optimized multi-dimensional RTK matrix pipeline computation - resulting in much higher RTK processing capability. These features and capabilities make the Yuneec H520E a top option for commercial-grade surveyors around the world.
