上海域格ASR平台cat1模块GPS功能介绍及测试

主推模块型号和功能介绍

域格YM310 A09 ASR cat1模块内置多星座高精度定位，支持 GPS、GLONASS、BDS、Galileo，QZSS，可多系统联合定位。可通过 AT 指令关闭与打开 GNSS 功能，具体见域格 AT 指令集。

模块小尺寸，高性能，超低功耗的 LTE Cat.1 bis + GNSS 定位二合一
无线通信模组。模组支持 LTE-FDD 和 LTE-TDD 网络数据连接通信协议，支持 LTE 3GPP
R13 Cat1，最高 10Mbps 下载速率和 5Mbps 上传速率。支持 WiFi SCAN 功能。
YM310 A09 设计为片式模组，采用 LCC+LGA 贴片封装，共有 109 个引脚。模组尺
寸只有 (17.7±0.1)mm*(15.8±0.1)mm*(2.3±0.15)mm。YM310 A09 小身材，大应用，其和主
流的 GSM 和NBIOT 模组尺寸相同，能满足几乎所有 M2M 应用需求。

我们还在支持单北斗的模组。

开发板GPS功能操作

我们EVB开发板可测试GPS，板子接USB可供电，GPS天线板子已做处理有源和无源天线都可支持，windows系统调试安装模块驱动发AT可直接打开GPS。

GPS 信息获取

模块开机 20S 后可通过 AT+CGPS=1 开启 GPS 功能，环境和天线正常的情况下，冷启动一般 45S 左右可成功获取定位信息。GPS 定位信息可通过 GPS 标准数据流或AT 命令获取。
GPS 标准数据流默认从 modem 口上报， 可以通过 AT+CGPSPORT 设置 GPS 标准数据流的上报端口。
AT+CGPSPORT=1 //modem 口上报 GPS 信息
AT+CGPSPORT=2 //AT 口上报 GPS 信息
AT+CGPSPORT=3 // UART 口上报 GPS 信息

如需要快速定位可以发AT+CGPS=4 下载星历快速定位，指令需要网络才能下载星历快速定位，如在无网络情况下发送跟AT+CGPS=1效果一样。

如何看GPS CN值

在GPS系统中，CN值是衡量接收机性能的重要指标之一。它表示接收机接收到的卫星信号的载波功率与噪声功率的比值。CN值越高，表示信号质量越好，接收机的定位精度和可靠性也越高。

这个用了专门测试GPS的工具，工具需要接模组串口才有数据，USB口不识别。

载噪比视图就是GPS天线信号，一般GPS定位需要4颗卫星，同时需要载噪比信号至少要到35以上才能正常定位，此图信号差没定位上。

信号达到35以上时成功定位上，GPS定位需要室外空旷地方定位你叫快，如在室外空旷地方定位时间比较长，可能是天线信号不行，建议用GPS专用天线。

信号值40以上的越多信号越好，定位就越快。
