GPS / GNSS Receiver Modules

Overview: small-size, low-power, highly accurate positions 

Septentrio GNSS receiver modules integrate the latest generation of GNSS technology, delivering highly accurate positions with minimal power consumption. While compact in size they fully retain the high-reliability and exceptional accuracy performance that Septentrio receivers are known for.  

True multi-frequency multi-constellation technology gives our module receivers access to every possible signal from all available GNSS satellite constellations including the U.S. GPS, European Galileo, Russian GLONASS, as well as BeiDou, QZSS and NAVIC. Septentrio’s advanced field-proven algorithms exploit this signal diversity to deliver maximum positioning availability and reference network compatibility.  

Key Benefits 

  • True multi-constellation, multi-frequency GNSS technology 

  • Compact, light-weight, low-power consumption 

  • Ideal for high volume  

GNSS Challenges 

GNSS receiver challenges 

GNSS module solutions 

Intentional or unintentional radio frequency interference also known as jamming can overpower GNSS signals resulting in lower positional accuracy. Malicious devices can “spoof” the position of the GPS receiver by overpowering GPS signals with false location information. 

Advanced Interference Monitoring and Mitigation (AIM+) technology shields receivers from jamming and spoofing. A graphical interface allows users to view the signals and helps locate interference sources. 

Multipath is caused by reflection of satellite signals off nearby building and other surfaces. It can cause errors in the positioning calculation.  

APME+ is an in-depth anti-multipath algorithm ensuring that only the direct signals are used for the positioning calculation.  Having the right GNSS antenna with excellent multipath rejection properties. 

Intense mechanical vibrations severely impacts tracking continuity. Many receivers cannot cope with this level of vibration and either stop computing the position, or provide a "smoothed" position which does not reflect the actual vibration. 

LOCK+ is Septentrio's technology to optimize the performance under vibration, shakes or shocks.  LOCK+ ensures a continuous position output, and that the computed position is accurately reflecting the actual position without lag or filtering. 

GNSS based positioning accuracy can be compromised by various factors. Earth’s atmosphere, including ionosphere and troposphere, degrades GNSS signals causing delays. GNSS satellites orbit the earth but can deviate slightly from their expected tracks.  Satellite clocks are extremely accurate however they still experience a very slight drift. If these errors are not accounted for, they can result in inaccuracies of several meters.  

GNSS corrections, such as RTK, SSR and DGNSS, provide region-specific data needed for compensation of GNSS errors. SBAS & PPP provide wide-region corrections helping improve these errors.  

Safety critical applications such as automotive need to know exactly how reliable is the receiver’s position at any given time.  

RAIM+ is a comprehensive integrity monitoring system allowing to monitor positioning quality at any given time.  

Precise positioning requiring cm-level accuracy even under challenging environments such as near high structures or under foliage.  

True multi-constellation multi-frequency GNSS receivers optimize positioning availability by being able to use all “visible” satellite at a given moment. Supporting all signals from all available GNSS enables full correction network compatibility thus getting the most out of RTK.
