Precision analysis of GPS height fitting for flat terrain
Abstract:The paper analyzes several GPS height fitting methods, and explains the advantages and disadvantages of fitting model. The precision of GPS height fitting was verified using plane fitting model by example in flat. Through analysis of precision, draw the conclusion of fitting height to replace fourth leveling and to provide technical support and theoretical basis for surveying and mapping.
Keywords: GPS height fitting model precision analysis
