  Abstract
  Many civil engineering and construction tasks require highly accurate land surveying information. The Global Navigation Satellite System (GNSS) provides positioning locations for land surveying and navigation technology. To achieve high accuracy, Real-Time Kinematic (RTK) differential correction method is mainly applied for Differential GNSS measurement. The Royal Thai Survey Department (RTSD) has established many local Continuously Operating Reference Stations (CORS). Information from CORS can be used for RTK differential correction via mobile Internet connection. However, many rural remote areas in Thailand such as forest, agricultural lands have no GSM mobile signal and Internet. The alternative solution is to use the GNSS L-band global correction service that is connected to a satellite communication system. Such system uses precise point positioning (PPP) technology to give corrected data for improving positioning measurement accuracy without internet connection requirement. This study employs is GNSS L-Band Global correction service for many test sites in Thailand and the results are compared with static. The user receiver accessing to GPS, GLONASS and BEIDU satellites, the static comparison study of Atlas L-Band correction and AUSPOS confirms centimeters horizontal accuracy and decimeters height accuracy.
