MOSAIC-H DUAL CHANNEL RTK RECEIVER PCB W/ MULTIBAND ANTENNA, SD CARD AND LIS3MDL

mosaic-H Overview

mosaic-H dual channel all-constellation multi-frequency top-performance high precision RTK GNSS receiver.

With dual-antenna input, mosaic-H provides precise and reliable heading combined with centimeter-level RTK positioning. With dual antenna GNSS, heading & pitch or heading & roll information is available immediately from the start, removing reliance on movement and helping initialization of INS solutions. It also provides an alternative to magnet-based heading sensors, which can be affected by metal.

Key Features

• AIM+: Advanced Interference Monitoring and Mitigation, offers built-in protection against intentional and unintentional jamming and spoofing using a sophisticated system of sampling and mitigation mechanisms. In robotic devices neighboring electronics can produce RF radiation which interferes with GNSS signals. AIM+ offers protection against such interference resulting in faster set-up time and robust continuous operation.
• RAIM+: Advanced Receiver Autonomous Integrity Monitoring comprises fault detection mechanisms of the receiver at all the levels including the generation of measurements, quality control and navigation algorithms. Detected faulty measurements, which are typically caused by high multipath or active ionosphere, are removed from the solution.
• IONO+: Activity in the ionosphere is a problem for GNSS signals, from loss of RTK fix to total loss of signal lock. Having honed our skills, supporting applications in the most iono-active areas on Earth, the result is IONO+: the most advanced protection against ionospheric disturbances to GNSS signals on any receiver.
• Software Support: mosaic-H supported by PX4 Autopilot, Ardupilot, AgOpenGPS and other software, supporting GPS for Yaw aka Moving Baseline.
