CHAPTER 6 Static Collecting Chapter Introduction ■ Introduction ■ The procedure of A8 static survey ■ Download data with USB ■ Management software operat ion for Static Survey 52
A8 GNSS RTK System Operation Manual Instruction A8 receiver can be used as dual-frequency static surveying instrument. The collected static survey data is saved in the memory in the main frame. The static survey data have to be downloaded to PC with post-processing software to process. The procedure of A8 static survey 1. Locate the instrument on a point, centering and leveling it. 2.
Static Collecting The satellite led flashing means th e instrument is tracking the satellites. The satellites are locked once the satellite led turns into constant on. Status led flashes due to your collection interval. If setting the interval to 1 second the led will flash once a second. 5. Turn off the instrument after the static survey is finished and record the turn-off time.
