An IMU costs anywhere from about $60 to around $100,000, depending on its grade. Consumer-grade IMUs run $60 to $100, industrial-grade $100 to $1,000, tactical-grade typically $5,000 to $25,000, and navigation-grade around $100,000. Our tactical-grade IMX-6 module is $480, and a complete GNSS-aided INS starts at $950.

Prices below are from our online store as of October 2026. Grade ranges are typical market prices, from our guide to the 4 grades of IMUs.

IMU prices by grade

Grade Typical price per unit Where it’s used
Consumer $60 to $100 Cell phones, automotive and commercial products
Industrial $100 to $1,000 Industrial robotics and vehicles
Tactical $5,000 to $25,000 Drones, delivery and agriculture robots, robotic lawn mowers, mobile industrial robots, autonomous marine vessels
Navigation Around $100,000 Commercial airliners, military aircraft, satellites

How much does an inertial navigation system (INS) cost?

An INS adds a GNSS receiver to the IMU so it can report position as well as orientation. Our GNSS-aided INS products run from $950 for a surface-mount module to $7,250 for a rugged unit with a Septentrio receiver. Every product below uses the same IMX-6 tactical-grade IMU at its core.

Product What it is Price
IMX-6 10-DOF module: tactical-grade IMU, magnetometer and barometer, with AHRS (no GNSS) $480
IK-1-IMX-6 IMX-6 on a breakout board for rapid prototyping $630
RUG-4-G0 IMX-6 in a rugged aluminum enclosure with RS232, RS485 and CAN; IMU / AHRS only, no GNSS $750
IG-2-IMX-6 Surface-mount GNSS-INS module: IMX-6 plus the dual-receiver, multi-frequency GPX-1 GNSS $950
RUG-4-GPX Rugged INS, GPX-1 receiver: 2 cm RTK, 0.4° heading, 10 Hz output $3,500
RUG-4-X20 Rugged INS, u-blox ZED-X20D receiver: 0.6 cm RTK, 0.1° heading, 20 Hz output $4,750
RUG-4-G5P3 Rugged INS, Septentrio mosaic-G5 P3H receiver: 0.6 cm RTK, 0.03° heading @ 5 m, 20 Hz output $6,000
RUG-4-G5P8 Rugged INS, Septentrio mosaic-G5 P8 receiver: 0.6 cm RTK, 0.03° heading @ 5 m, 100 Hz output $7,250

Need GNSS on its own? The GPX-1 multi-frequency GNSS receiver module is $300.

What makes one INS cost more than another?

  • The GNSS receiver. Across the rugged RUG-4 line the IMU is the same; the receiver sets the price. Moving from the GPX-1 ($3,500) to a Septentrio mosaic-G5 P8 ($7,250) takes heading from 0.4° to 0.03° @ 5 m, RTK from 2 cm to 0.6 cm, and output from 10 Hz to 100 Hz.
  • The enclosure and interfaces. The bare IMX-6 module is $480. The same sensor in a rugged aluminum enclosure with RS232, RS485 and CAN (RUG-4-G0) is $750.
  • The grade of the IMU. Higher grades have better sensor specifications and cost more; see the grade table above.

Do I need a development kit?

A development kit costs $150 to $250 more than the unit on its own and is the quickest way to evaluate it. The IG-2-IMX-6-DK ($1,150) contains the IG-2-IMX-6 module, interface cables, two GNSS antennas, software and engineering support hours. The RUG-4-GPX-DK ($3,750) contains a RUG-4-GPX, two antennas and the USB interface cable.

Is there volume pricing?

Yes. Buying in volume lowers the cost per unit. Contact our sales team or email sales@inertialsense.com with your quantity for a quote.

What replaced the IMX-5?

The IMX-5 has reached end-of-life, and the IMX-6 is its successor. See IMX-5 replacement options.
