摘　　要：针对江苏某高速公路改扩建工程构建全球导航卫星系统(GNSS)工程控制网并进行外业观测,对观测数据进行检核计算,分析三维无约束平差和二维约束平差结果。结果表明:GNSS工程控制网内、外符合度好,网形设计良好,成果质量可靠。Taking a highway reconstruction and expansion project in Jiangsu province as a test area,the GNSS engineering control network was constructed and field observation was carried out.The observation data were checked and calculated.The results of three-dimensional unconstrained adjustment and two-dimensional constrained adjustment show that GNSS engineering control network has good internal and external conformity,good network shape design and reliable quality.
