Precision is a subjective word in the world of GNSS. For some applications, metre-level accuracy is “good enough”, even with the potential for errors and position jumps. Other applications require highly precise centimetre-level positioning that is reliable and available 24/7 over a wide area.

Whatever the desired accuracy, advances in GNSS correction services have greatly improved the availability and performance of positioning solutions. Sara Masterson, business development manager of correction services at NovAtel, said, “The corrections industry overall is constantly evolving and improving the available correction service options in support of the user community, extending the range and types of conditions under which the service can be delivered.”
