GPS+PPS Time Sync #30

Open adhipermana opened 3 years ago

Hai Rian

I have a problem when using the openpylivox program when I want to synchronize UTC time against my lidar livox horizon data. Can you help me how to synchronize this UTC time ?, i use GPS data from the BX305 GNSS receiver and retrieve the GPRMC serial data through my computer, how do I add this PGSS data information to the lidar data using this openpylivox program?

Thanks

Hello, Thanks for raising this issue/question. I'll have to dig into the specifics on what timing information is supported by the Horizon (and other Livox sensors) as I know the Mid-40 does not support absolute timing information in the form of a GPRMC message directly (i.e., not using a Livox Hub) and rather only supports the relative PPS RS485 timing signal. I am aware that support for external timing signals within OPL is currently missing, but I will improve support for this within upcoming OPL commits. Thanks, Ryan
