Description
High stability GNSS aided Inertial Navigation System (INS) that provides accurate and reliable Position, Velocity, Time (PVT) and Attitude (roll, pitch, yaw) under the most demanding conditions.
It contains an 9-axis MEMS IMU (Cost-effective IMU or High Stability IMU), dual antenna multi-constellation multi-frequency OEM GNSS module and interfaces module that have embedded MCUs with algorithms for Extended Kalman Filter, PPP and dual antenna RTK-engine.
The robust loosely-coupled GNSS+INS integration provides superior performance during GNSS signal outages that makes it ideal solution for systems requiring continuous positioning. GNSS+INS integration combines calibrated IMU data with dual antenna RTK data. These are coupled in a fusion algorithm to deliver accurate and reliable navigation and orientation by the adaptive Kalman Filter.
The raw GNSS measurements are available for user’s secondary processing as well as API functions for his/her developments.
Different types of wireless (GSM/LTE, Wi-Fi, NB IoT, LoRA, UHF) and wired (Ethernet, RS422) interfaces may be available for interested user. They allow to accept signals from various Differential Correction Services.
Use our software tool designed to full control and management of the GNSS receiver.
Our technical support will answer all questions and help with equipment setup.
It has four hardware options:
A: cost-effective IMU-based, without wireless interface
B: cost-effective IMU-based, with wireless interface
C: high stability IMU-based, without wireless interface
D: high stability IMU-based, with wireless interface
