Introduction
The ZYM-GM626 Smart GNSS Receiver is a compact GNSS positioning solution based on the ZhongKe Microelectronics AT6668B SoC. It is designed for applications such as vehicle navigation, mapping, surveying, security, and agriculture. With a clear view of the sky and a stable power supply, the unit provides reliable positioning and communicates with external devices via an RS232-compatible interface. Built-in backup memory helps retain essential satellite data.
Featuring low power consumption, the GM626 can track up to 99 satellites, re-acquire signals within 100 ms, and update position data once per second. Trickle-Power reduces energy use through intermittent operation, while Push-to-Fix enables a quick position fix even when the receiver is normally powered off.
