Centimeter positioning
Centimeter positioning
Two Q43 GNSS Helical RTK Modules are used as an RTK Base Station
and RTK Mobile Station respectively
By setting up continuous running reference station and outputting the differential correction data on the ground known fixed coordinates using the Q43 module which is configured in base station mode, or by paid RTK base station enhanced services, transmitting differential correction data to Q43 terminals which uploading rough positioning data, the terminals, with errors like multipath refraction, Ionospheric, and Tropospheric Refraction, are able to calculate error value in real time, for centimeter-level positioning in seconds.
