The Topnet Live Annual 200 Hour Limited Usage licence is an essential solution for businesses that need the flexibility of a high-precision GNSS network without the commitment of a full-time subscription. It bridges the gap between hiring a base station and paying for an unlimited annual licence, making it one of the most cost-effective ways to achieve centimetre-level accuracy on a budget. This package includes an industrial-grade 4-network roaming SIM, which is a game-changer for UK site work. Instead of struggling with a single network's dead zones, the SIM automatically switches between EE, Vodafone, O2, and Three to find the best possible data connection. This ensures that the VRS (Virtual Reference Station) corrections reach your rover reliably, allowing for instant initialisations and high-precision mapping regardless of whether you are in a city centre or a rural field. With 200 hours of "engine time," this licence is perfectly scaled for users who perform roughly 25 full days of field work per year. It removes the need for physical base station setups, saving hours of site time and reducing the risk of equipment theft or movement. Whether you are using a Topcon, Leica, or Trimble rover, this licence provides the high-fidelity correction data needed for modern digital construction workflows.
