Over the past 15 years in the inertial navigation industry, I’ve seen a wide range of IMU pricing based on various factors, including the type of gyroscope technology, accuracy, and application. Whether you are looking for an IMU for military, aerospace, or industrial applications, understanding the pricing structure is key to ensuring you make the right investment.
The price range for Inertial Measurement Units (IMUs) depends on the technology used and the level of accuracy. Basic MEMS IMUs typically range from $20 to $1,000. Higher-precision MEMS IMUs range from $1,000 to $10,000. Fiber Optic Gyroscope (FOG) IMUs usually cost between $10,000 and $100,000. High-end military-grade IMUs with some specialized systems can exceed $100,000.
In this article, I’ll break down the factors that affect IMU pricing and give you a clearer idea of what you can expect to pay based on your specific needs.

What Factors Influence the Price of an Inertial Measurement Unit (IMU)?
The price of an IMU can vary widely depending on several factors, which include the type of IMU, sensor accuracy, and specific features offered. Typically, there are three broad categories of IMUs:
| IMU Type | Typical Price Range | Primary Use | Accuracy |
|---|---|---|---|
| Low-End MEMS IMUs | $20 - $1,000 | Consumer electronics, robotics | Moderate accuracy |
| High-Precision MEMS IMUs | $1,000 - $10,000 | Military, aerospace, high-performance | High precision |
| Fiber Optic Gyroscope (FOG) | $10,000 - $100,000 | Aerospace, defense, high-reliability | High precision |
| Ring Laser Gyroscope (RLG) | $50,000 - $100,000+ | Military, missile guidance, aerospace | Ultra-high precision |
- Low-End MEMS IMUs: These are the most affordable and are used in consumer electronics or low-cost navigation systems. Prices typically fall between $100 and $1,000 for these basic systems.
- High-Precision MEMS IMUs: These advanced MEMS IMUs offer high accuracy and can be used in military, aerospace, and industrial applications. Prices for these IMUs range from $1,000 to $10,000, offering a great balance between affordability and high performance.
- Fiber Optic Gyroscope (FOG)-Based IMUs: FOG-based systems provide exceptional accuracy and are often used in demanding applications such as aerospace, military navigation, and submarine guidance. These systems typically cost between $10,000 and $100,000.
- Ring Laser Gyroscope (RLG)-Based IMUs: These are the most expensive IMUs, designed for military-grade systems or high-precision aerospace applications where sub-micro radian accuracy is required. Prices for RLG IMUs can exceed $50,000, with some specialized systems exceeding $100,000.
How Do IMU Features Affect Pricing?
The accuracy required for an IMU directly affects its cost. IMUs used for military, aerospace, or missile guidance applications typically require sub-micro to nano-radian precision, which adds to the cost of the system. The higher the precision needed, the more you will pay.
| Accuracy Level | Application | Price Range |
|---|---|---|
| Low to Moderate | Consumer electronics, basic navigation | $20 - $1,000 |
| High Precision | Industrial robotics, military, aerospace | $1,000 - $50,000 |
| Ultra-High Precision | Military, missile guidance, aerospace | $50,000 - $100,000+ |
- Low to Moderate Accuracy: For basic applications, such as consumer electronics or low-cost robotics, a basic MEMS IMU with moderate accuracy is sufficient. These systems are priced in the $20 to $1,000
- High Precision: Systems requiring high precision for applications such as industrial robotics or aerospace typically range from $1,000 to $50,000.
- Ultra-High Precision: Military and aerospace-grade systems that need sub-micro radian accuracy typically fall into the $50,000 to $100,000 range, with some systems exceeding $100,000 for extremely demanding applications like missile guidance or high-precision navigation.
Are IMU Prices Affected by Application?
As in any industry, the application of an IMU significantly influences its pricing. Below, I’ve categorized different sectors and their typical IMU needs:
| Application | IMU Type | Price Range | Features |
|---|---|---|---|
| Military & Defense | High-Precision MEMS, FOG, RLG | $10,000 - $100,000+ | High accuracy, rugged, ITAR compliant |
| Aerospace | FOG, RLG, High-Precision MEMS | $10,000 - $100,000+ | High Accuracy, Temperature & vibration resistant |
| Industrial | Low to High-Precision MEMS | $1,000 - $10,000 | Basic to moderate accuracy, robust |
| Consumer Electronics | Low-End MEMS | $100 - $1,000 | Moderate accuracy, cost-effective |
- Military & Defense: IMUs used in military systems need to meet high standards of accuracy, durability, and environmental resistance, which can push the price to $10,000 – $100,000. Some military-grade IMUs can exceed this range based on customization and security features.
- Aerospace: Aerospace IMUs, used in systems like aircraft navigation and satellite control, often need to withstand extreme temperatures, high altitudes, and vibrations. These systems typically fall into the $10,000 – $100,000+.
- Industrial Applications: For industries like robotics and automated systems, the required accuracy is typically lower than military and aerospace applications, which makes them more affordable—ranging from $1,000 to $10,000 depending on the complexity and performance requirements.
Does the Customization of IMUs Impact the Price?
Many clients require customized IMUs to meet specific needs. Customization is a key factor that drives up the cost of an IMU. The more specialized your requirements, the higher the price. For example, if you need a high-accuracy IMU with specific features like temperature resistance or shock durability, or if you require integration with complex systems, the price can increase. Custom features may include:
- Environmental protection(e.g., sealing for water resistance or shockproof designs).
- Multi-sensor fusion(to improve performance in harsh environments).
- Special softwareintegration for data analysis and remote monitoring.
Customization often increases the price by 20% to 30% or more depending on the complexity of the requirements.
How Does Bulk Purchasing Affect IMU Prices?
For larger companies or military organizations purchasing IMUs in bulk, volume discounts can significantly reduce the cost per unit. Depending on the contract terms and the number of units required, long-term relationships with suppliers can also result in more favorable pricing.
