Introduction
iRTK can be used as dual-frequency static surveying
instrument. You can double click F1, when the voice reminds
you, press power button to fix. After the setting is done, the red
status LED flashes once while collecting an epoch in a few
seconds (depends on the setting of sampling interval). The
collected static survey data is saved in the memory card of the
main frame. The static survey data have to be downloaded to
PC with post-processing software to be processed.
Procedure of iRTK Static Survey
1. Locate the instrument on a control point, do centering and
leveling.
2. Measure the height of instrument for three times, on
condition that the difference of each measuring is less than
3mm and the final height of the instrument should be the
average height. The height of instrument should be defined
from the controlling point of base centre to upper edge of
marker line. The antenna radius of iRTK receiver is 0.087
meter; the height of phase center is 0.0765 meter.
