High-Efficiency and Well-Integrity Method for Dynamic Acquisition of GNSS Location Information

摘要：

Location-based services play an ever increasingly important role in modern society. The high efficiency and well integrity of GNSS location information is required in these services. For well integrity, a new dynamic transmission processing method named Transmission Intelligent Selecting Mechanism (TISM) is presented in this paper. Based on the detection of communication signal, different methods for information processing are selected for different signal intensity For high efficiency, a new dynamic compression method named Time-Interval Alternated with Distance Interval Intelligent Judging Method (TAD) is presented based on traditional compression methods Single TimeIn ternal method (STD and Single Distance-Internal method (SDI). There are three different modes, high speed mode, medium speed mode and low speed mode in TAD. For different modes, different compression styles are selected. Experimental results sbow that TISM has made location information acquired successfully in some areas where the GPRS signal is very weak. TAD has reduced more than 75％ of data and 50％ of deviation comparing with STI. Thus, more than 75％ of communication cost has been reserved.
