RDP clients should be able to relay location (GPS) and compass data to the server as part of the RDP protocol. This way, an old tablet with poor processing capabilities can remote in to a vastly superior device and still be useful for navigation.
Just to clarify: I use Samsung Galay Tab S devices (SM-T805) to remote in to my home PC running windows 10 over the 4G network. I can't use navigation apps on my home PC because, well, it always shows it's location as at my house. If the data from the tablet's on board location and compass devices could be relayed to the 'server' over RDP this problem would be resolved. This data would use considerably less bandwidth than the existing option to relay microphone audio.
I see this as significantly improving the usefulness of devices that are becoming computationally inadequate.
