    [1] It requires a subscription to data service. [2] The RTX accuracies depend on correction service chosen. And 95% of the time with initializations are around 5-30 minutes. [3] RTK XTRa also requires a subscription to the data service, and precision is dependent on GNSS satellite availability. RTK XTRa positioning ends after 5 minutes of radio downtime.
