What is an INS?
An inertial navigation system (INS) combines an IMU with one or more aiding sources, most commonly a GNSS receiver, and fuses the data through an Extended Kalman Filter to produce a continuous, real-time estimate of position, velocity, and attitude. Where an IMU alone accumulates drift over time, an INS uses external corrections to bind that drift and deliver accurate navigation data over extended missions.
VectorNav's INS starts with an individually calibrated, temperature-compensated IMU, the same inertial foundation trusted across 120,000 deployed systems. From there, VectorNav’s proprietary Extended Kalman Filter refined through over a decade of real-world feedback fuses IMU and GNSS data into a deterministic, mathematically traceable navigation solution at up to 400 Hz.
For any platform that needs to know where it is, how fast it's moving, and which direction it's pointed, VectorNav delivers navigation you can trust.
WHY VECTORNAV
PIONEERING THE SMALLEST FULLY-INTEGRATED GNSS/INS
In 2012, VectorNav introduced the first surface-mount GNSS/INS module on the market, establishing the benchmark for SWaP-optimized navigation.
Today, VectorNav’s INS solutions remain among the smallest and lightest in their performance class—enabling integration where competitors simply cannot fit.
INS EXPERTISE REFINED ACROSS TWO DECADES OF REAL-WORLD DEPLOYMENTS
VectorNav’s inertial navigation systems are engineered by a team that has spent nearly two decades advancing Extended Kalman Filter-based sensor fusion for precision, reliability, and resilience. Deployed across hundreds of platforms in operational environments, VectorNav's INS architecture continues to evolve — gaining capability and performance from every real-world mission it supports.
ANY PLATFORM. ANY MISSION. ANY CONDITION.
VectorNav INS solutions are engineered to be application-agnostic. Four packaging options and two sensor performance levels offer maximum SWaP flexibility and integration compatibility. No matter the mission, VectorNav has a navigation solution.
INTEGRATING ADVANCED GNSS TECHNOLOGIES
VectorNav’s INS solutions combine the latest GNSS receiver technology with our high-performance IMU to deliver accurate, dependable position, attitude, and velocity data you can count on.
Leveraging multi-constellation and multi-frequency receivers, VectorNav delivers robustness and resilience in GNSS-denied, degraded, or contested environments.
FAST TO FIELD, SIMPLE TO INTEGRATE.
INS units ship in under one week for Industrial and three to four weeks for Tactical. Every unit arrives fully calibrated, factory-tested, and ready for integration with comprehensive SDK support, detailed documentation, and direct access to VectorNav’s applications engineering team.
