Team, Do we support D-GPS (differetial GPS) in our MCs? Explicitly - MC75A? http://www.esri.com/news/arcuser/0103/differential1of2.html As far as I understand SIRFStar III chipset itself has D-GPS functionality ( WAAS, MSAS, EGNOS as said here http://en.wikipedia.org/wiki/SiRFstarIII but do we have this enabled or provide a way to enable this on the hardware level? If not - any known/recommended software solution which may receive the corrections over the network and apply them into the standard GPS stream? Thanks, Valery
