Atomic GPS Base V2.0 is a GPS positioning module designed for the Atom series of hosts. It integrates a high-performance AT6668 chip, featuring a built-in MAX2659 low-noise amplifier and a ceramic antenna, delivering precise and reliable satellite positioning services. This module utilizes the NMEA0183 4.1 protocol for output and supports multi-frequency and multi-mode GNSS signal reception. It can receive signals from multiple satellite navigation systems, including GPS, BD2, BD3, GLONASS, GALILEO, and QZSS.
The Atomic GPS Base V2.0 is highly versatile, making it ideal for applications requiring high-precision multi-system joint positioning as well as single-system independent positioning. With robust anti-interference capabilities and exceptional positioning accuracy, it is particularly suitable for vehicle navigation, IoT positioning devices, industrial automation, robotic positioning, and drone applications.
