Due to the way the headers are organized a single change in a
AP_GPS backend would trigger a rebuild for most of the files in the
project. Time could be saved by using ccache (since most of the things
didn't change) but we can do better, i.e. re-organize
the headers so we don't have to re-build everything.
This makes internal headers internal and then other libraries only
depend on the AP_GPS.h header.
This is the SBP driver for Piksi, Lodestar and other forthcoming Swift Navigation GPSes.
This driver currently implements three things:
- Implements a lightweight SBP protocol detection system
- Implements Piksi as a single-point-positioning GPS (same as ublox/others)
- Implements hardware logging of GPS health and baseline messages
Forthcoming iin future updates:
- Need to implement the RTK functionality
This is a complete rewrite of the GPS driver structure, with a static
main driver and separate backend drivers. This will allow proper
support for multiple GPSes, and will allow parameters to be set on the
GPS object
