Single-Frequency L1 GNSS+INS Integrated Navigation Module
JS-RP26-U is a high-performance, low-power single-frequency (L1) GNSS module with built-in inertial navigation. It adopts hardware-software integrated low-power design to maintain high performance while reducing power consumption.
Equipped with an advanced anti-multipath & anti-interference RF front-end and 8 anti-single-tone interference filters for L1 band, it greatly improves actual positioning and first fix time. Supports GNSS+INS integrated navigation, AGPS, SBAS, differential positioning and adaptive installation.
It is widely used in rail transit, maritime navigation, drones, automotive navigation and emergency rescue scenarios.
