Reliable GNSS Performance

Centimeter accuracy and full multi-constellation support means I can trust it in tricky placements. Setup was quick and intuitive.

Compact and Durable

I’ve used this receiver in different weather conditions, including light rain, and it’s held up well. The build feels solid despite the small size. Accuracy has been consistent, and it’s now part of my regular field equipment.

Solid Performance for the Price

This receiver offers great value for money. Setup was straightforward, and connecting to NTRIP corrections was smooth. I mainly use it for boundary mapping, and the centimeter-level accuracy meets my expectations. For its size and price, it performs really well.

Great for Field Surveying and Mapping Work

As a survey technician, I needed a compact and reliable RTK solution that integrates smoothly with our mobile data collection workflows. This receiver’s multi-constellation support and fast RTK initialization save me a ton of setup time. On several projects, it provided stable centimeter-level accuracy and maintained a steady connection with NTRIP corrections throughout the day. I also appreciate how quick the device powers up and gets a fix — it’s less than five seconds in most conditions, which is fantastic when you’re repeating measurements across multiple jobsites.

Great Entry RTK Receiver

If you want reliable RTK positioning without spending a fortune on high-end gear, this is a very solid choice. Accuracy and durability are both excellent.
