本文将选用一块支持 BDS/GPS 双模定位并具有低功耗特 点的芯片 ATGM332D-5N-3X 作为手持定位终端的定位模块。 ATGM332D-5N-3X 支持两种卫星导航系统进行组合定位，包括中国的 BDS （北斗卫星导航系统）， 美国的 GPS 。该模块具有 32 个跟踪通道，两个卫星导航系统的 GNSS 信号可同 时被接收，从而实现联合定位的功能。 ATGM332D-5N-3X 模块具有高灵敏度、 低功耗、低成本等特点，适用于船舶导航、车载导航、可穿戴设备等。(This article will choose a piece of support BDS/GPS Dual mode positioning with low power consumption Point chip ATGM332D-5N-3X As a positioning module for a handheld positioning terminal. ATGM332D-5N-3X Support two satellite navigation systems for combined positioning, including China. BDS (Beidou satellite navigation system), American GPS . The module has Thirty-two A tracking channel, two satellite navigation systems GNSS Signal can be identical It is received and the function of joint location is achieved. ATGM332D-5N-3X The module has high sensitivity, Low power consumption, low cost and other characteristics, suitable for ship navigation, vehicle navigation, wearable devices, etc.)

本程序代码通过AVR ATmega88单片机运行PID运算算法，对于智能化的跟踪控制是必不可少的，输出可通过PWM输出控制电机或者两位输出控制继电器输出，都能达到非常好的控制效果。(This program code through the AVR ATmega88 microcontroller operation PID algorithm, for intelligent tracking control is essential, the output can be output through the PWM control motor or two bit output control relay output, can achieve very good control effect.)
