Frequently Asked Questions (FAQs)

What’s the difference between the base & rover kit and the network rover system?

The base and rover kit requires setting up a physical base station that transmits corrections to the rover via UHF radio. The network rover system connects to virtual reference stations (VRS) or CORS networks over cellular data, eliminating the need for a base station and allowing quicker setups.

Is Hemisphere RTK GPS compatible with my existing field software?

Yes, Hemisphere RTK GPS integrates smoothly with most leading land surveying software and data collectors, supporting various data formats and communication protocols for easy workflow integration.

How do I set up the S631 with my total station or data collector?

Bench Mark provides detailed setup guides and training resources to help you connect the S631 GNSS receiver with your total station or data collector for synchronized data capture and survey operations.

Does Bench Mark offer training and post-sale support?

Absolutely. Bench Mark offers expert training, setup assistance and ongoing technical support to ensure you maximize the capabilities of your Hemisphere RTK GPS system.

Can I use the Hemisphere RTK GPS in remote or low-signal areas?

Yes. The S631 supports both UHF radio communication for off-network setups and cellular network RTK where coverage exists. Its multi-constellation support and advanced signal tracking improve performance even in challenging environments.
