Inertial Labs, Inc. developer and supplier of high performance Inertial Sensors & Systems, recently released its
Industrial and
Tactical grade IMU-P, MEMS Inertial Measurement Units.
Since its introduction in 2015, the IMU-P received much acclaim as a MEMS Inertial Measurement Unit. The IMU-P's outstanding reliability and accuracy in challenging environments -- such as high vibration, rapidly changing temperature extremes, and tough mission profiles -- grew its success.
In addition to selling as a stand alone IMU, the IMU-P is integrated into Inertial Labs' AHRS, MRU, and GPS-Aided INS products.
Growing demand for industrial and tactical
In order to satisfy market demands for Industrial and Tactical grade Inertial Measurement Units, Inertial Labs released two versions of the IMU-P:
- IMU-P Industrial, with gyroscope residual Bias error over temperature of less than 100 deg/hr (72 deg/hr typical);
- IMU-P Tactical, with gyroscope residual Bias error over temperature of less than 30 deg/hr (20 deg/hr typical);
The IMU-P Industrial is an excellent solution for stabilization and pointing, where a very efficient and low cost IMU can be an alternative to FOG based systems for EOS stabilization and Line of Sight pointing applications.
IMU-P Tactical is a compact, lightweight, and affordable solution with high performance gyroscopes: 1 deg/hr in-run Bias stability and 30 deg/hr maximum Bias error over its operational temperature range (-40°C to 85°C), and superior accelerometers: 5 micro g in-run Bias stability and 0.5 mg Bias residual error over its operational temperature range. This performance, coupled with its small size and cost, gives IMU-P Tactical a distinct advantage over existing MEMS IMUs on the market.
Both models of IMU-P, Industrial and Tactical output high precision Pitch and Roll with 0.05 deg dynamic accuracy.
IMU-P applications
The high performance IMU-P works in various tactical guidance, navigation, flight control, stabilization, and pointing systems. Due to its high performance level, IMU-P provides an excellent alternative to legacy tactical grade FOG IMU’s providing advantages in size, weight, power, and cost (SWaPC).
The device also supports the functions of existing IMUs on the market.
For example, the IMU-P is configurable to have the same mechanical and electrical interface as the STIM300. Thus, it acts as a drop-in replacement to STIM300 for approximately half the price. Other publicly available and published protocols can be supported as well. This provides customers a lower cost alternative for their existing designs without additional development costs.
"More than one thousand delivered is a significant milestone signifying product maturity and customer acceptance," said Jamie Marraccini, Inertial Labs’ CEO & President. "Inertial Labs continues to invest in the IMU-P and in our IMU-P based AHRS, MRU, and GPS-Aided INS products."

GNSS receiver manufacturer Septentrio recently announced the launch of the next generation AsteRx-i. The announcement occurred at IEEE/ION Position Location and Navigation Symposium in Monterey, US.
The AsteRx-i combines Septentrio’s latest compact, multi-frequency multi-constellation GNSS engine with an external industrial grade MEMS based IMU.
It delivers accurate and reliable GNSS/IMU integrated positioning to the cm-level. It also delivers full 3D attitude at high update rates and low latency.
