The JS-RP26-2 is a dual-band (L1/L5) GNSS module that combines high performance with low power consumption. Its advanced low-power design optimizes multi-band and multi-mode signal tracking, featuring anti-multipath and anti-interference RF front-end with up to eight anti-interference filters. Ideal for wearable devices, trackers, drones, and automotive navigation, it delivers improved positioning and TTFF performance.
