Features

■ New-generation Nebulas-II SoC chip
The K482 works with Sunnav’s new-generation all-system multi-core high-precision GNSS SoC -- Nebulas-II. The chip supports 432 channels, two 600MHz ARM processors and dedicated high-speed floating-point coprocessors, achieving powerful satellite signal processing.
■ “UGypsophila”RTK processing technology
The K482 adopts Sunnav’s new-generation “UGypsophila” RTK processing technology and takes advantage of the high-performance data sharing capability and super-simplified operating system within the NebulasII GNSS SoC. It performs sufficient optimization on the multi-dimensional RTK matrix pipeline computation,resulting in 80%+ higher RTK processing capability.
■ Adaptive recognition of RTCM
The K482 performs pattern matching recognition and correction algorithm with the internally-abstracted RTCM protocol template to fully implement the differential RTCM input adaptation function. Upon the RTCM data access, it judges quickly the input COM port and RTCM3.2/3.0/2.3 format, without the need to specify the type of differential data, thus dramatically simplifying user operations.
■ On-board MEMS integrated navigation
The K482 integrates the on-board MEMS chip and U-Fusion integrated navigation algorithm, resulting in optimized continuity and reliability of heading/positioning output in such complex environments as buildings, tunnels and overpasses. Inputs of odometer and external higher-performance inertial components are supported*.
