Tactical-Grade Integrated GNSS/INS

aSense210 / 310 / 320 Tactical-Grade INS Series

Combining tactical-grade aSense IMUs with an RTK-GNSS receiver compatible with all satellite constellations, the aSense INS family delivers precise position, velocity and orientation — with AHRS, barometer integration, dual-antenna heading, odometer/speed-log/air-data inputs and embedded transfer alignment.

Tactical-Grade Core

A Tactical-Grade IMU Inside Every aSense INS

Every aSense INS is built on an aSense tactical-grade MEMS IMU, calibrated across the full operating temperature range. When GNSS is jammed, spoofed or lost, that inertial core — fused with external aiding — keeps the navigation solution stable.

INS model	IMU core	Gyro bias stability	GNSS antenna
aSense210-INS	aSense110-IMU	≤2.5 °/h	Single
aSense310-INS	aSense110-IMU	≤2.5 °/h	Dual
aSense320-INS	aSense120-IMU	≤1.1 °/h	Dual

FAQ

Tactical-Grade INS — Frequently Asked Questions

What is a tactical-grade INS?

An inertial navigation system built on a tactical-grade IMU (gyro bias stability roughly 0.5–10 °/h). Fused with GNSS and external aiding, it delivers precise navigation and bridges GNSS outages far longer than consumer-grade systems.

Single or dual antenna — which do I need?

A dual-antenna INS (aSense310/320) measures heading directly from GNSS, even when stationary or at low speed. A single-antenna INS (aSense210) derives heading from motion, which suits platforms that are always moving.

What happens when GNSS is lost?

The tactical-grade IMU core carries the solution, while external aiding — odometer, speed log, DVL, air data or radar Doppler — limits drift, keeping accuracy through outages longer than one hour.
