Buy RTK GNSS Receiver: The Complete Septentrio-Powered Buyer’s Guide

To buy an RTK GNSS receiver that holds centimetre accuracy in real conditions, match three things to your platform: single or dual antenna, update rate, and form factor. This guide compares every Eview RTK receiver, all powered by Septentrio modules (mosaic-X5, mosaic-H, mosaic-G5 and AsteRx-m3 Pro+) with AIM+ anti-jamming, and shows which one fits each application.
What RTK gives you, and why the GNSS module matters
Real-Time Kinematic (RTK) positioning uses corrections from a base station or network to reach centimetre accuracy. Every Eview receiver is rated at 0.6 cm + 0.5 ppm horizontal and 1 cm + 1 ppm vertical, with about 7 s initialisation. See how RTK works.
The module inside sets everything else: how many signals it tracks, how fast it outputs, whether it gives heading and how well it copes with interference. Septentrio AIM+ anti-jamming is on by default in every Eview receiver.
Five questions to answer before you buy
- Do you need heading? Dual-antenna receivers give 0.15° heading at 1 m spacing without a magnetometer. See dual-antenna heading receivers.
- How fast is your control loop? Survey and mapping work well at 20 Hz. Fast vehicles and flight controllers benefit from 100 Hz output with under 10 ms latency.
- How much weight and power can you spare? mosaic-G5 receivers use the least power, from 0.44 W on the HB50.
- Where do corrections come from? Use NTRIP, your own base such as the HB62, or Galileo HAS on mosaic-G5 products for decimetre-level accuracy without a base.
- Do you need signal authentication? mosaic-X5 and mosaic-G5 receivers support Galileo OSNMA.

Which RTK receiver should you buy?
Drones and UAVs
The ultralight HB52 / HB52H and the HBEV322 smart antenna suit weight-limited airframes; the HB10 suits fast platforms that need 100 Hz with heading. See RTK GNSS for drones.
Surveying and base stations
Run the HB62 as a rugged base with NTRIP and 64 GB logging, and use the HBEV11 or HB6 as a rover. See GNSS for surveying and GIS.
Machine control and vehicles
The HB56H gives heading in a flange-mount metal housing; the HB10 and HB59 add 100 Hz output with under 10 ms latency. See construction and mining and precision agriculture.
Robots and AMRs
The HBEV322, HB52 and low-power HB50H fit compact robots. See RTK GNSS for robots.
Marine
The HB6 Pro and HB56H give true heading that steel hulls cannot disturb. See marine GNSS heading.
OEM integration
The HB59 board brings AsteRx-m3 Pro+ performance with Ethernet, and the G5P3H EVK lets you evaluate the mosaic-G5 P3H before you design it in.

Frequently asked questions
What RTK accuracy do Eview receivers give?
All Eview receivers use Septentrio modules rated at 0.6 cm + 0.5 ppm horizontal and 1 cm + 1 ppm vertical in RTK, with about 7 s initialisation. At 10 km from the base, the distance term adds about 5 mm horizontally.
Which Eview receivers output 100 Hz?
The HB10 and HB59 (AsteRx-m3 Pro+) and the HB6, HB56 and HB62 (mosaic-X5) output position at up to 100 Hz. mosaic-G5 products run at up to 20 Hz, and the mosaic-H HB6 Pro and HB56H give RTK with heading at up to 20 Hz.
Do I need a dual-antenna receiver?
Choose dual antenna when your platform needs true heading while stationary or moving slowly, such as tractors, boats, robots and hovering drones. Dual-antenna models give 0.15° heading at a 1 m antenna spacing. For position only, a single-antenna receiver is enough.
What is the difference between mosaic-X5 and mosaic-G5?
The mosaic-X5 tracks all bands on 448 channels and outputs up to 100 Hz. The mosaic-G5 has 789 channels, quad-band tracking, about 40% lower power and a 2.2 g module, at up to 20 Hz, and Septentrio lists Galileo HAS support for it.
