- L-band for SECORX worldwide corrections
- 4G/LTE connectivity
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.
