ZK-M1021-GPS

Civilian car networking GPS chip

 

Product introduction

ZK-M1021-GPS is a BDS/GPS/GLONASS/QZSS/SBAS high timing chip with high performance and high integration. Chips use radiation. The integrated design of frequency and baseband integrates DC-DC, LDO, power management, POR, RF processing, satellite digital baseband processing positioning and navigation, 32-bit RISC CPU, RAM, flash storage, Watchdog, timer, RTC, antenna status detection and short circuit protection circuit. The chip supports UART, I2C, SPI, SQI, GPIO, Ex_INT, 1PPS, programmable time stamp and other rich interfaces, and supports integrated navigation, A-GNSS, D-GNSS.

Features

ZK-1021-GPS has the characteristics of high performance, high integration, small size, low power consumption, low cost and anti-interference. It can be directly compatible with the replacement of mainstream GPS products, greatly reducing replacement costs and shortening replacement time.

High performance positioning and navigation system

- Supports three satellite systems: BDS, GPS and GNSS

- Support SBAS and QZSS
