@Chris-P

to answer my own question, I checked the voxl-vision-px4 code and the system time will be set once from gps time (when valid) if it has not been set yet by ntp or manually.

@Alex-Gardner

Thanks for the clarification. I am planning to have a local network enabled but without internet/ntp server. Is there a way to trigger the gps time sync manually in this situation ?

Chris

I would like to be able to synchronize event across multiple platform by using gps time (or unix time based on gps time).

I checked the gps_raw_int message which contains a timestamp but it only seems to be the time since boot and not an unix timestamp. It also seems like the sys_timestamp message might have a gps converted unix time but I am not sure if this message is available as a MPA pipe on the voxl side.

Any pointer to get gps time synchronization would be appreciated !

Thanks Steve,

I went to compile the source code with the voxl emulator and it compiled without issues.

Is there an existing package to get ZMQ (c++ binding) available on the platform ?

Thank you!
