GPS - UTM timestamp info #3

Closed gcielniak closed 5 years ago

gcielniak commented 5 years ago

There seems to be a quite long delay between the GPS and velodyne observations at the moment and there is currently no way of recovering the right timestamp from the GPS observation (the one reported in the NMEA string). This feature would be needed to synchronise the sensors. @marc-hanheide any ideas how to add that to the published messages? Should that replace timestamp (clients local time) or perhaps better to have both of them (e.g. gps_timestamp).

Hi, the timestamp should be taken from the actual GPS response and not be generated by the Ros component. I can look into this, but here's the property that should be included in the response from JavaScript:
