Go out oneself to the distance correction of satellite, and unification uploads to data center, base station and data center constitute ground enhancing
System (difference broadcasts platform).Difference broadcasts platform in real time by this data is activation to the terminal device for needing positioning.Terminal sets
For while moonscope is carried out, also receive difference and broadcast the differential data that platform sends, and its positioning result is carried out
Correction, so as to improve positioning precision.Difference is generally divided into carrier phase differential data and pseudo range difference data, is respectively used to terminal
Equipment carries out carrier phase difference (RTK, Real Time Kinematic) positioning and pseudo range difference (RTD, Real Time
Differential) position, wherein carrier phase differential positioning, high precision, but it is high to equipment requirement, and cost is also high, availability
It is low, it is used primarily in survey field；Pseudo range difference is positioned, and low for equipment requirements, low cost, availability is high, moderate accuracy, Ke Yiyong
In civil navigation field.
