GPS measurement operation scheme refers to the operating scheme used to determine the relative position between the stations with the help of GPS technology. Point coordinate precision obtained is not the same; its operating methods and observation time are also different, thus having different range of applications.
Galaxy G1 communication facilities (telephone and telegraph, post and telecommunications) and power supply, for power between the stations and equipments. §3.1 Static operating §3.1.1 Static Measurements Profile Static measurements: GPS positioning measurement by installed three (or more) GNSS receivers to perform simultaneous observation and determine the relative position between the stations.
Galaxy G1 §3.1.
Galaxy G1 §3.1.3 Field operation notes: 1)Static mode of Galaxy G1 receiver only to set in EGStar software or other software (Such as Field Genius or SurvCE), please refer to the EGStar manual for more information. 2)Set up a tripod on the Control point, leveling and centering strictly on the measuring point. 3)Measure the instrument height three times, the difference of the results shall not be more than 3 mm, and average the results.
Galaxy G1 the original ground control network. Coincidence point generally should not be less than three (should perform leveling conjunction when not enough) and should be evenly distributed in the network in order to reliably determine the transformation parameters between the GPS and Ground Networks. 3) The points of the GPS network coinciding with the leveling points should be considered.
Galaxy G1 the measurement point in the specified coordinate system. Depending on the modes of transmission of the differential signal, RTK is divided into the radio mode and network mode. This section first describes the radio mode, as shown below: Base mode with External Radio §3.2.
Galaxy G1 of impact on the GPS signal reception and emission of radio signals. 1) The receiver is set to the base station with external radio mode; 2) Set up tripods, the tripod on which to put the radio antenna should be placed at a higher point, the least distance between the two tripods should be 3metres. 3) fix the base and the base station receiver, (if set at a known point, a strict leveling should be done), power on the base station receiver.
