Gladiator Technologies introduces small, high-performance GNSS/INS

Gladiator Technologies’ low-noise inertial sensor and systems technology coupled with Velox high-speed processing are now integrated with a 72-channel GNSS receiver to provide compact GNSS/inertial navigation systems (INS) for accurate position, velocity and attitude.

The feature set was carefully selected to suit several positioning, navigation and timing (PNT) applications including flight control, navigation and stabilization for imaging, platforms and antennas.

The high-performance LandMark 60 INS/GPS and compact LandMark 005 INS/GPS both feature advanced sensor-fusion technology, combining GNSS position data with Gladiator Technologies’ low-noise, high output inertial sensors as well as barometric pressure and magnetometers.

Both products feature Gladiator Technologies’ proprietary Velox processing technology and extended Kalman filter (EKF), enabling precision position information during short-term GPS outages.

Velox Technology combined with the new EKF enable the LandMark INS/GPS products to have accuracy of less than 2 nautical miles per hour during short-term GPS outages.

The LandMark 60 INS/GPS is the top performing unit with +/- 0.3° heading accuracy and pitch/roll angle measurements of 0.1°. It is also available with an option for a real-time kinematic (RTK) GPS receiver.

The small and robust LandMark 005 INS/GPS is less than 35 square centimeters and is suitable for space-constrained applications that require a high standard of INS/GPS performance.

“Our low-noise sensor inputs to the EKF are enhanced by an adaptive estimation algorithm,” said Lee Dunbar, chief software architect. “This, along with extended precision for the nonlinear solution integrator, maximizes the accuracy of position, velocity and attitude. Customer configurable EKF parameters are present to allow optimization for their applications.”

“Leveraging our inertial capability into a complete INS/GPS package was a natural progression for our product line,” said Eric Yates, Gladiator Technologies’ new business development manager. “With the LandMark 005 INS/GPS and LandMark 60 INS/GPS we’re offering an exceptional MEMS-based INS/GPS that fits in the palm of your hand.”

A development kit is available for set-up, configuration and data collection.

IMU offers low-noise performance for high dynamic applications

Higher rate, higher acceleration applications benefit from SWaP-C advantages of MEMS-based inertial systems.

Gladiator Technologies’ LandMark 007 inertial measurement unit (IMU) combines low noise, high range sensors and Velox high-speed output in a rugged IMU package measuring 0.7 inches square. With rate ranges up to 2000°/s and acceleration ranges as high as 200 g, the LandMark 007 IMU provides demanding, precision performance for a range of high dynamic, rugged applications.

All LandMark 007 IMUs feature Velox high-speed message timing to minimize digital message phase lag. They also include high-speed output data rates (up to 10 kHz) for measurement accuracy and flexibility.

These high-speed features are complemented by low-noise gyros with a gyro angle random walk (ARW) of <0.0035°/s/√Hz (0.15°/√hr) and low-noise accelerometers with a velocity random walk (VRW) of <6 mg/√Hz.

“The LandMark 007 IMU is uniquely designed to meet the industry’s need for a compact, rugged and high performance, cost-effective IMU. Extensive conditioning and testing ensure reliable, stable measurements for our customers with high dynamic applications,” said Eric Yates, Gladiator Technologies’ sales manager. “We are seeing strong interest in the LandMark 007 and LandMark 007X IMUs from applications which otherwise have been limited to highly specialized, and therefore expensive, IMU solutions.”

IMUs with less than or equal to 98 g linear acceleration range are designated as LandMark 007 IMUs. IMUs with greater than 98g linear acceleration range are designated as LandMark 007X IMUs. The LandMark 007 IMU is exported categorized as ECCN7A994 and the LandMark 007X is export categorized as ECCN7A103.

A LandMark 007 IMU development kit is available for set-up, configuration and data collection.

Gladiator Technologies has introduced a three-axis, inertial rate system gyroscope. The G300D gyro is 0.67 cubic inches, low power and high speed, making it suitable for image stabilization applications, the company said.

The G300D has message timing under 150 microseconds and output data rates up to 8 kHz with external sync. A micro-electro-mechanical gyroscope, it has an ARW of <0.0028 degrees/sec/√Hz and an option for both 24 and 32-Bit LSB for exceptional resolution.

Users can configure the G300D to their desired configuration using a software development kit or through software protocols to simplify the integration process.

“The G300D, with a 250-Hz bandwidth, allows user to replace more complicated and expensive gyros for image stabilization applications,” said Rand Hulsing, chief scientist at Gladiator Technologies. “The three-axis package is also convenient for mounting in any orientation for tight space requirements.”

“The G300D product is a good example of our SX-series architecture, which has enabled Gladiator to extend our sensor fusion technologies into high speed applications with message latency under 150 usec,” said Lee Dunbar, chief software architect at Gladiator Technologies. “This output offers minimal phase lag like an analog sensor by virtually eliminating typical signal processing and digital conversion overheads.”

The G300D gyro is non-ITAR.
