The 3200 acre soybean farm has carried out farmland boundary confirmation, irrigation channel terrain acquisition, agricultural machinery automatic driving coordinate calibration, large open grassland, and only a small number of low shrubs block the satellite.

The TK-800 base station is fixed at the commanding point of the farm, the long-distance UHF radio covers the whole farmland, and the weak area of the network depends on the differential stability of the local radio; It can be combined with Dajiang UAV to complete aerial survey modeling of the whole farm and quickly divide the ownership range of the plot.

Six groups of farmers are equipped with TK-200 mobile station to carry out field collection. The whole machine is only 500g, extremely lightweight, and there is no burden for long-time field walking; Built in 16GB mass storage, no TF card slot, no capacity expansion, enough to store the boundary coordinates of all plots in a single area.

Portuguese voice broadcast is suitable for local farmers, and zero base personnel can independently complete the inflection point collection of the plot in half a day; The equipment is compatible with multi class radio protocol, and can work cooperatively with the old surveying and mapping terminal of the farm

The duration of farmland surveying and mapping was shortened by 70%, and the loss of agricultural machinery and materials was reduced by 12%; Bulk purchase of TK-200 greatly reduces the project budget, and the comprehensive purchase cost is 38% lower than that of other imported equipment.
