Enhanced GNSS Heading Receiver
The Septentrio AsteRx RB3 Pro+ is a Rugged Dual-Antenna GNSS Receiver with advanced Multi-Frequency, Multi-Constellation GNSS Satellite signal tracking, 100Hz Update Rate, IP69k certification, 16GB Internal Memory and utilises Septentrio’s proprietary GNSS+ technology suite to not only achieve but maintain true, reliable centimetre-level RTK solutions.
The implementation of state-of-the-art capabilities such as AIM+, IONO+, APME+, RAIM+ and LOCK+ promises GNSS signal tracking and RTK-Fixed solutions where other brands fail.
It has been tested and tempered under the extreme and unforgiving testing environments to withstand the most severe and harshest working environments, and even in these conditions, the AsteRx RB3 Pro+ will deliver PVT and Heading to the purest and most accurate degree.
Key Strengths
Reliable Heading: Dual-antenna input ensures precise GNSS heading combined with centimeter-level RTK.
Extreme Environment Ready: Ultra-rugged housing with multi-frequency tracking, GNSS+, and high-update/low-latency outputs for fast feedback during movement or rotation.
Integration Made Easy: Fully documented interfaces, commands, and software tools enable quick system integration.
