GNSS COORDINATE SYSTEMS CONFIGURATION USING SURPAD.

adminConfigurationsNo Comments

GNSS receivers have different data collecting softwares depending on the operating system (windows & android versions).

Below are the configuration parameters used in various data collecting softwares in the datum or coordinate system parameters for better accuracies when using averaged coordinates with CORS based or RTK Base/Rover system. The configuration parameters are standard for all GNSS receivers make & models using Surpad.
