Hi.
Tight timing synchronization is important for a lot of data capture and sensor fusion applications.
The de-facto way to get globally synchronized clocks today is to use a GNSS receiver and their supplied pulse-per-second (PPS) interrupt pin.
The pixhawk connector standard DS-009, does not include a PPS input on the GPS-ports. Because of this, manufacturers of GPS modules do not produce modules with PPS output.
I would really like it if manufacturers of GPS modules had a PPS output, but this will probably not happen unless it becomes a part of the pixhawk standard.
Some concrete questions:
- Is there any roadmap for a new revision of the Pixhawk connector standard, DS-009?
- If yes, how will this new standard revision be governed and developed?
