Gladiator Technologies’ High-Performance Integrated GNSS-INSs Come Easily to Hand

Low-noise MEMS inertial sensor and systems technology coupled with VELOX high-speed processing are integrated with a 72-channel GNSS receiver from Gladiator Technologies. The devices deliver position accuracy within 2 nautical miles per hour during GPS outages.

The compact inertial navigation systems-GNSS (INS/GPS) sensors deliver accurate position, velocity and attitude suited to PNT applications including flight control, navigation as well as stabilization for imaging, platforms and antennas. The 72-channel GNSS receiver is capable of receiving GPS, GLONASS, Galileo, BeiDou, QZSS & SBAS.

The LandMark60 INS/GPS (shown above) and compact LandMark005 INS/GPS both feature advanced sensor fusion technology, combining GPS 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.

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

The EKF enhancement in particular makes these competitive products for unmanned systems, defense and space applications.

The INS/GPS products are extensions of Gladiator’s longstanding inertial products line released in 2017. The new INS/GPS products employ the same inertial package as their respective IMUs, while adding a GPS receiver, barometer, magnetometers and extended Kalman Filter for combined INS/GPS output.

“Leveraging our inertial capability into a complete INS/GPS package was a natural progression for our product line,” added 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.”

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 real-time kinematics (RTK) GPS Receiver.

The small and robust LandMark 005 INS/GPS is less than 35 cm3 and is especially well suited for space-constrained applications that require a high standard of INS/GPS performance.
