What is the difference between Radio RTK and Mobile RTK?

Radio RTK relies on a base station that broadcasts correction signals over UHF radio frequencies to nearby equipment, typically effective within a 20-kilometer (~12 mile) radius. This method requires line-of-sight between the base station and machinery for optimal performance. In contrast, Mobile RTK leverages cellular networks to access correction data from Continuously Operating Reference Station (CORS) networks. This approach allows for greater flexibility and coverage, especially in areas with robust cellular service, and reduces the need for a physical base station on-site.
