JS-RP26-U

IMU Dead Reckoning Modules

The JS-RP26-U is a single-frequency (L1) GNSS module with an integrated inertial navigation unit, offering high performance and low power consumption. It features advanced low-power design and supports optimized multi-band, multi-mode signal tracking. With anti-multipath and anti-interference RF front-end technology, it provides up to eight anti-interference filters for L1, improving positioning and TTFF performance. Ideal for applications in railways, maritime navigation, UAVs, and automotive systems.
