Currently only GLL messages (only containing location information) are parsed. It would be useful if parsing of GPRMC messages could be done also including speed and direction information

hello, livox team
我最近在使用激光雷达和相机进行同步,问题是这样的,之前的avia系列都是支持PPS + GPRMC同步,因此我的硬件设置基本上都是按照这个模式来的。并且1代的driver里面有专门的设置能够很简单就完成同步。
所以我的问题是这样的。在2代的driver中,这样的同步方式是否还支持,如果支持,应该怎么设置呢?

When I transmit a gpssim.bin file built with this software, the "speed over ground" in the $GPRMC messages output by the receiver I am using to record the transmission is always inconsistent (much slo…

I believe the parsing code for the $GPRMC message is treating the position coordinates incorrectly.
```C
latm = atoi(&nmea_params[3].str[2]);
nmea_params[3].str[2] = '\0';
latd = atoi(n…

Store GPS info every X seconds into a log file on the SD card.
I think there is a correct format to use it on google earth, for example.
Here is a sample on the log generated by one of my radios:

我在时间同步的过程中发现,输入的gprmc是整秒可以实现硬件同步,如果gprmc带毫秒同步失败,是因为mid360只支持整秒同步啊

目前我们采用的是GPS时间同步方法,即这种:
GPS:为了实现GPS同步,雷达/Hub需要同时接收PPS和UTC时间戳。对于Horizon/Tele-15/Mid-70/Avia,雷达单元可以通过以太网在控制指令中获得UTC时间戳。Livox Hub可以通过RS485串口在$GPRMC信息中获得UTC时间戳。
测试设备:
Horizon 和 Tele 15
我们进行了如下测试:
