Altus NR3

The Altus NR3 combines easy-to-use, multi-frequency, quad-constellation RTK with an unrivalled communications toolset for a successful survey or GIS project every time. It incorporates leading GNSS and wireless technology into a sleek and compact design.

Altus NR3 Septentrio GNSS receiver

Key features

  • Robust, light and portable GNSS receiver
  • Quad-constellation, multi-frequency, all-in-view RTK positioning
  • AIM+ anti-jamming and monitoring system
  • Easy setup and one-touch logging
  • All-in-one base and rover operation

AIM+ anti-jamming and monitoring system

AIM+ offers built-in protection against intentional and unintentional jamming using a sophisticated system of sampling and mitigation mechanisms. The Altus NR3 can suppress the widest variety of interferers from simple continuous narrow-band signals to the more complex wide band and pulsed transmitters as well as lnmarsat and Iridium satellite transmissions.

The GNSS+ toolkit

Septentrio’s suite of algorithms to convert bad measurements into good positioning

Mechanical vibrations or shocks caused by rough terrain can wreak havoc with satellite tracking. Lock+ automatically adjusts the tracking loop parameters of the Altus NR3 so you never lose position.

Activity in the ionosphere is a problem for GNSS signals, from loss of RTK fix to total loss of signal lock. Having honed our skills in the most iono-active areas on Earth, the result is IONO+: the most advanced protection against ionospheric disturbances to GNSS signals on any receiver.

Metal and large nearby structures can reflect GNSS signals and produce multipath. The APME+ system disentangles direct and reflected signals enhancing both position and measurement quality. APME+ is bias free and, in line with Septentrio’s commitment to maximum configurability, can be disabled.
