The Altus NR3 is a high quality GPS receiver. This receiver is made by the European company Septentrio. They are settled in Belgium.

Altus NR3 works great with Apglos Survey Wizard

From all GPS receivers the Altus NR3 was the first receiver that ever got connected with Apglos Survey Wizard. After a one time set-up of the GPS receiver you can work forever with the combination of this GNSS receiver and Apglos Survey Wizard. It is an awesome combination.

Key features of the Altus NR3

This receiver has an exceptional performance and is very reliable. It has multi-frequency RTK that sets the new standard in positioning performance. It includes APME+ industry-leading multipath technology and IONO+ to ensure position accuracy under the most intense ionosperic activity. These features together with LOCK+, to maintain tracking during mechanical shocks or vibrations, combine to offer the best possible quality of measurments for Altus NR3’s GNSS position calculations.

It also has a great interference robustness. The Altus NR3’s AIM+ is quite simply, the most advance on board anti-jamming technology on the market. It can suppress the widest variety of interferers, from simple continuous narrowband signals to most comples wideband and pulsed jammers. The RF spectrum can be viewed on the web UI in real-time in both time and frequecy domains.

So to be short, this GPS receiver is the most reliable in the field.

Benefits of the Altus NR3

And there is already the main benefit. It is reliable and trustworthy. This means that it won’t give you a fixed position if the position is not fixed. That makes this Altus NR3 special. And it makes this GNSS receiver the best pick if you want everything to be accurate.

Of course another benefit is that this Altus NR3 works great with Apglos Survey Wizard. Apglos Survey Wizard is an easy-to-use land survey app. You can download it for free on the Google Play Store. And if you want to know first more about this software then check out this page. There is told everything about all the features of this land survey app.

Another benefit is the web interface to configure this GNSS receiver. It is very easy to use. So it is easy to set up the Altus NR3 to your needs. You can even store different settings in the receiver. So with only a few clicks you can restore the previous settings.

Altus NR3 manual

Knowing how this GNSS receiver works is important before you buy it. That is why there are two documents. To understand how the Altus NR3 works there is a quick start user guide and a user manual.

After reading the Altus NR3 manual or if you don’t have that much time the quick start user guide then you will know how it works. And the good thing is that you can download them both here:
