Description
REYAX RYS8839 is an ultra-low power, L1 L5 Dual-band GNSS module that support multi-constellation including: GPS(L1C/A,L5), GLONASS(L1OF), BeiDou(B1I. B1C, B2a), Galileo(E1, E5a), QZSS(L1C/A, L1S, L1C/B, L5), IRNSS NavIC(L5), SBAS(L1). As the latest addition to REYAX’s GNSS portfolio, this module has integrated digital noise filters for coexistence with other radio systems.
Based on the Sony® CXD5610GF Engine and the dimension of only 11*8*2.2 mm, the RYS8839 has a sensitivity of -167 dBm during tracking and provide 1m high accuracy with position update rate up to 25Hz. With 1 second in hot start and within 24 second in cold start, the quick-start feature allows RYS8839 can apply precise positioning and navigation services anytime, anywhere.
Compare to other GNSS modules that only can track L1 signals, the GNSS signals from L1 L5 dual-frequency bands enables the RYS8839 can achieve both higher positioning accuracy and speed even in other difficult transmission conditions like dense urban canyons. This module can effectively reduce the multipath effects, shorten the time of acquire data and improve positioning accuracy, thereby resulting in optimum performance.
