FAQ

How do I choose the right GNSS product for my application?

Qtalis offers high-precision GNSS modules and receivers suitable for applications such as surveying and mapping, UAVs, robotics, autonomous driving, precision agriculture, construction machinery, and intelligent transportation. Different models vary in accuracy, interfaces, and features, so users can choose the most suitable product based on their specific application needs.

What is the difference between RTK and standard GNSS positioning?

Standard GNSS typically provides meter-level positioning accuracy, while RTK (Real-Time Kinematic) can achieve centimeter-level or even higher precision. Many Qtalis products support RTK technology, making them ideal for professional or industrial applications with high accuracy requirements.

Can I get better accuracy without connecting to an RTK Base station?

Qtalis products support free PPP-B2B service and PPP-HAS services, which provide 20cm horizontal accuracy without any other correction input. Qtalis also supports SBAS services like WAAS, EGNOS, MSAS, GAGAN, SouthPAN, to provide sub-meter accuracy.

Are technical support and firmware updates provided after purchase?

Yes. Qtalis provides professional technical support and continuously optimizes firmware and performance based on product development. Users can access technical documentation, firmware updates, and support through our website, forum, or customer service channels.
