Patent ID: 7149629

Claim:
A Land Surveyor System with Reprocessing (LSSRP) comprising: an Aided Inertial Navigation System (AINS) providing a sequence of time-indexed present position values in response to the LSSRP being moved from a first known position value at the start of a survey interval to a second known position value at the end of the survey interval, a Position Computing System (PCS) coupled to receive and store the sequence of time-indexed present position values as a surveyor carries the LSSRP from the first known position to the second known position, the PCS and the AINS being integrally coupled into a package, the package further comprising: a means for inputting and time-indexing successive first and second known present position values at respective successive known present position fixes, each successive pair of known present position values establishing the beginning and end of a survey interval, the PCS having a reprocessing computer and program means coupled to receive and store the successive time-indexed known present position fix values for processing the indexed present position values with a Modified Bryson-Frazier smoother (MBFS) algorithm to provide indexed and adjusted present position values for at least some of the indexed present position values between the first known position fix value at the start of the survey interval and the second known position fix value at the end of the survey interval.
