Drone Inertial Navigation System

What is a drone INS?

An inertial navigation system combines IMU measurements with GNSS to deliver position attitude and heading. It maintains stable navigation when GNSS is noisy or briefly unavailable.

Do I need INS or only IMU?

An IMU outputs raw acceleration and angular rate. An INS fuses those with GNSS to estimate full navigation states. For mapping inspection and BVLOS missions an INS is preferred.

What accuracy should I choose

Match accuracy to the mission. Basic stabilization can use entry accuracy. Mapping and long range flights benefit from tighter attitude accuracy and dual antenna heading with RTK support.

Does an INS replace GPS?

No. The INS works with GNSS to bound drift. RTK GNSS improves position while the INS stabilizes attitude and heading during outages.

Which autopilots are supported?

Most models here integrate with Pixhawk Ardupilot or Cube using UART CAN Ethernet and PPS timing. Check each product page for driver availability and output rates.

How fast should the output update rate be?

Gimbal stabilization and control benefit from 100 Hz or higher for attitude while navigation messages can be lower depending on the autopilot.

How are prices determined?

Price depends on accuracy grade interfaces dual antenna heading ruggedization and GNSS options. Use the request link for a current quote and lead time.

What is the difference between UAV INS and aircraft INS?

UAV units prioritize low weight power and easy integration while manned aircraft systems focus on high certification levels and long term stability.
