SkyMEMS Accelerometers are based on silicon MEMS capacitive sensors, which offer higher performances in terms of size, power, reliability, long-term stability, signal to noise and robustness.
SkyMEMS Accelerometers have been widely used in the high speed train, they are used to monitor several types of mechanical motions such as inertial force (acceleration), tilt (inclination), vibration and shock.

MA1000A Accelerometer widely used in Seismic monitoring
Earthquake early warning systems use earthquake science and the technology of monitoring systems to alert devices and people when shaking waves generated by an earthquake are expected to arrive at their location. The seconds to minutes of advance warning can allow people and systems to take actions to protect life and property from destructive shaking.
Accelerometers are usually used where precision records of smaller seismic events are required. SkyMEMS accelerometers provides low noise and low frequency accelerometers, it can accurately measure the vibration changes, which are widely used in the seismic monitoring systems.

MA1000A Accelerometer widely used in inertial navigation system
Inertial navigation system (INS) is a system that composed of a computer, motion sensors (accelerometers), rotation sensors (gyroscopes) and occasionally magnetic sensors (magnetometers), to continuously calculate the position, the orientation and the velocity of a moving object without the need for external references. It is used on vehicles such as ships, aircraft, submarines, guided missiles and spacecraft.
SkyMEMS accelerometers have been widely used in the inertial navigation systems, including IMU, AHRS, MRU, etc. It enjoys high performance and high stability in harsh environment.
