ZHONGKEWEI ATGM336H-F8N76

The ATGM336H-F8N series module is a high-performance, full-constellation, multi-frequency GNSS positioning and navigation module measuring 10.1×9.7mm. This series supports multiple satellite navigation systems, including BeiDou-2, BeiDou-3, GPS, QZSS, SBAS, GLONASS, GALILEO, and IRNSS, with support for L1, L2, and L5 frequency bands, enabling simultaneous signal reception from these systems for combined positioning, navigation, and timing. The module employs proprietary rapid satellite acquisition technology to quickly capture a large number of visible satellites, achieving fast and accurate positioning with significantly improved performance in challenging environments such as urban canyons. Its integrated high-performance embedded CPU supports a position update rate of up to 20Hz. The module also integrates a proprietary hardware-accelerated anti-jamming circuit for rapid detection and suppression of RF interference, along with a high-precision timing engine with timing accuracy better than 10 nanoseconds. This module adopts a new all-in-one navigation SoC chip technology, featuring high integration, high performance, low power consumption, and a compact form factor.
