为了充分发挥 ATGM336H-5N 的优良性能,用户在使用本模块时需要注意以下几点:
 +
 +
* 采用低纹波的 LDO 电源,将纹波控制在 50mVpp 以内。
 +
* 模块附近尽量不要走其它频率高、幅度大的数字信号。模块下面全部以地线填充为佳。
 +
* 天线接口尽量靠近模块的 RF 输入引脚,并注意 50 欧姆的阻抗匹配。
 +
* 模块本身具有有源天线接入、拔出、短路检测电路,同时在天线意外短路时,对天线的供电电流进行限制(50mA),起到保护的作用。
 +
 +
在上述 3 种天线端口状态发生变化时,可以从串口输出相应的信息。如

  • $GNGGA: Time, position, and fix related data of the receiver.
  • $GNGLL: Position, time and fix status.
  • $GNGSA/$GPGSA/$BDGSA: Used to represent the ID’s of satellites which are used for position fix. When both GPS and Beidou

satellites are used in position solution, a $GNGSA sentence is used for GPS satellites and another $GNGSA sentence is used for Beidou satellites. When only GPS satellites are used for position fix, a single $GPGSA sentence is output. When only Beidou satellites are used, a single $BDGSA sentence is output.

  • $GPGSV/$BDGSV: Satellite information about elevation, azimuth and CNR, $GPGSV is used for GPS satellites, while
  • $BDGSV is used for Beidou satellites
  • $GNRMC: Time, date, position, course and speed data.
  • $GNVTG: Course and speed relative to the ground.
  • $GNZDA: UTC, day, month and year and time zone.
