At centimeter unit for real time kinematics measurement and control in the midst of flying accurate global positioning system receiver

摘要

(57) Abstract The system example of this invention 4 yes observation die GPS receivers of the opposite which locks (12) with, 4 yes observation GPS receivers of the opposite which swinging is done (14) with, the code and carrier measurable quantity at those time includes with the communication link in order duplex you distinguish to convert. Carrier phase integer ambiguity is solved efficiently by searching the narrow lane intersection where the L1 crest and the L2 crest which are spread by the GPS satellite which traces both happen simultaneously. Information of constraint outside like height can use the integer ambiguity settlement addition in order to accelerate. The data with the standard station and the swinging body at systematic interval, for example per 1 seconds of each epoch 1 times is communicated in the form which was compressed, part measurable quantity of carrier phase more frequently, for example per 1 seconds during 10 obtaining and epoch is used in order to be spread solution.
