Abstract:
A networked system for providing differentially corrected position information to a rover unit, said networked system comprising:a server station, said server station having a differential correction engine for differentially correcting position information when requested;a reference station communicatively coupleable to said server station, said reference station providing differential correction data to said server station such that said server station is able to utilize said differential correction data when differentially correcting position information;a rover unit communicatively coupleable to said server station, said rover unit having a position generation engine for providing position information of said rover unit, said rover unit further adapted to request said server station to differentially correct said position information of said rover unit and return differentially corrected position information of said rover unit to said rover unit such that said rover unit acquires said differentially corrected position information upon demand without requiring said rover unit to have a differential correction engine integral therewith.
