Select the GNSS source

[Pat-I]

The OG modules Should bring the GNSS sentences in proprietary PGN number we would create. having 3 PGNs: one for tractor, one for blade 1 (or side 1) and one for blade 2 (or side 2)
Or simply one Byte as number, so up to 255 IDs possible

OG3D can then have 3 sources: these three(or more), plus the AgIO source (USB or UDP) and the USB from OG3D (unless we erase all serial traces in OG3D)

Then You activate tractor position (if desired) and select the source
The first blade source is always active: select the source
Second blade option (or second side of blade): select the source

With a tractor, the heading would be calculated from the antennas.
If two blades, you must select either Dual antenna (one blade, antenna equally apart from center)
or: two blades back at back (antennas centred)

The OG3D output will be 2 PGNs for both blade height and delta.

The the blade module will do the valve calculations
