Common Questions


A MEMS-based Inertial Navigation System (INS) is a navigation solution created using Inertial Measurement Unit (IMU) sensors made from micro-electromechanical systems, otherwise known as MEMS. MEMS chips are under 5mm in size, meaning the IMUs in use are quite small and lightweight. This allows navigation systems to be light and small, which broadens the range of applications a MEMS INS can be used for. The INS is composed of MEMS chips and a CPU. The raw data from the MEMS IMUs are fed into the CPU to calculate attitude, velocity and position.

Why should you use a MEMS INS?

Compared to other INS solutions, a MEMS INS has a lower size, weight, power consumption and cost (SWaP-C). There are several benefits to using a MEMS INS: 

  1. Reduced cost: A MEMS INS is not as costly as a FOG-based (fibre optic gyroscope) INS 
  2. Lightweight and small: By nature, MEMS are built on a miniature scale and measure in micrometres. This makes a MEMS-based INS an ideal fit for vehicles or machines that need a small payload. 
  3. Flexible placement: The more compact nature of MEMS technology also allows the INS to be mounted in variable positions 
  4. A wide range of applications: While FOG INS has been proven to be incredibly effective, improvements to the accuracy of MEMS technology for inertial navigation solutions have proven to be more cost-effective for applications such as precision agriculture and autonomous vehicles 
  5. GNSS integration: A with any kind of inertial navigation system, a MEMS INS isn’t able to determine absolute position. By itself, the MEMS INS is able to determine the relative position of the vehicle from a known starting point, accounting for distance travelled and orientation. When a MEMS INS is combined with GNSS (global navigation satellite system) it takes advantage of the satellite technology to accurately determine the absolute position on Earth. With these two navigational technologies working in tandem, the strengths of both enable a high level of accuracy.
  6. Low power consumption: MEMS technology has advanced to the point where they can reduce power used, utilising power cycling and low power modes 

Given the low SWaP-C of MEMS INS, it has a wide range of applications, from commercial-grade to survey-grade and defence-grade. This includes:

  • Smartphones
  • Precision agriculture
  • LiDAR
  • Radar
  • Aerial surveying
  • Marine surveying
  • Space exploration
  • Ultrasonic sensors
  • Cameras
  • Wearable technology

How does a MEMS sensor work for inertial navigation?

A MEMS INS calculates changes in an object’s position and movement. This is achieved through the functions of inertial sensors like three-axis gyroscopes and accelerometers that measure changes in orientation, rotation, and velocity. As the object moves, MEMS sensors pick up on these changes to accurately measure how it moves and the speed at which it travels. This can be combined with data from a GNSS (Global Navigation Satellite System) to accurately determine a vehicle’s location. The satellite data from the GNSS will feed more information into the central unit, providing additional information on the travel of the object and providing more insights as to what the IMU is measuring. 

How does a MEMS accelerometer work?

A MEMS accelerometer senses the forces of acceleration acting on a vehicle or device. A common array uses an outer assembly with a series of fixed plates with a movable assembly located internally. This internal assembly has a small mass and is connected to the outer assembly with spring contacts.  It also has internal plates that form multiple capacitors. As force is implemented the internal assembly moves and this displacement changes the capacitance value which is measured to determine the acceleration that has been applied.  

How does a MEMS gyroscope work?

A MEMS gyroscope measures the rate of rotation. Unlike an accelerometer, a gyroscope uses a two-mass system that moves in opposite directions continuously, experiencing equal velocity. When the vehicle or device has angular rotation applied the MEMS gyroscope will begin to measure the difference in velocity, also known as the Coriolis Force.

How does a MEMS magnetometer work?

A MEMS magnetometer is used to detect and measure magnetic fields. One sensing method used by MEMs magnetometers is special resistors that have a strong magnetic field applied during manufacture to orient their magnetic domains in the same direction. During operation, any external magnetic field applied to the resistor causes the magnetization to rotate and change the angle. This can be measured as a variation in the resistance.

How does a MEMS pressure sensor work?

MEMS pressure sensors typically use piezoresistive pressure sensors. The piezoresistive sensor measures changes in the electrical resistance when pressure is applied.
