I am a handheld GPS precision is low, how to use to be able to improve certain accuracy.
If you can join the CORS network, the accuracy of decimeter to centimeter level.
If the carrier phase measurement function is not available, you have the maximum accuracy of GPS accuracy of 1-10This can only improve the observation environment using SBAS and other ways to improve the accuracy
Look at the maximum accuracy of GPSIf the difference accuracy can reach 1cm you can connect CORS single base station and other network RTK way to achieve the corresponding accuracy
