Welcome to our community!
I know by myself that locating underground utilities can sometimes be a challenging and time-consuming process. I’ll describe some features of our products and answer your questions down below.
Multi-band vs. single-band
As you’re surveying utilities, I guess that you’re generally working in urban areas. In such an environment, a multi-band Reach RS2 or Reach M2 will be the optimal choice for you. They can get a fixed solution in partially blocked sky conditions and on baselines up to 60 km in RTK and 100 km in PPK.
Single-band receivers need a clear sky view and can get fix on baselines up to 10 km in RTK and 30 km in PPK accordingly.
To learn more about the differences between single-band and multi-band receivers, you can check the special guide in our docs.
Reach M2 vs. Reach RS2
Our Reach M2 is generally designed for integration with other hardware. It is small and has many ports required for integration. It should be connected to an external power source and GNSS antenna. It doesn’t have dust and water protection.
Reach RS2 is a field-ready solution. It’s durable and protected from water and dust. It has an integrated GNSS antenna and battery. The receiver can hold up the charge up to 16 hours in RTK mode with a cellular module enabled.
Positioning accuracy of a standalone receiver
A standalone receiver provides positioning of a few meters of accuracy. If you need a centimeter-accurate positioning, you should use the second receiver as a base. As an alternative, you can connect your receiver to an NTRIP service.
Reach devices can output their position via Bluetooth or Serial port in industry-standard NMEA 0183 format. You can check if your RD device can input position stream from an external GNSS receiver. You can find a full description of this feature in the position streaming guide in our docs.
