PORT TECHNOLOGY CONSTRUCTION CONSULTING & COMMERCIAL JSC THAI BINH THERMAL POWER PLANT AND TRANSMISSION LINES CONSTRUCTION PROJECT Report on Establishment of the Permanent and Temporary Benchmark Horizontal control network was connected to at 02 National control points (III130420 and III-130419 ) IV order horizontal control network was carried out include 04 sessions Each session, the signal of satellites was recored for at least 120 minutes All survey information of each measured point such as weather condition, Antenna’s height, number of satellite were recorded into daily report… All data collected at each point were recorded into memory card or internal memory with 10 seconds interval separately by names for post-processing Network adjustment Trimble Business Centre software was used for baselines processing and network adjustment Adjustment module was used for control network adjustment In order to reduce an affect of scale factor and according to technical specification, the network was adjusted in VN-2000 coordinate system central meridian 105 30’, zone (Ko=0.9999) Weighting value of all GPS solution is calculated based on “alternative” method After calculating,
