|Position Accuracy within 2 NMPH during GPS Outages
Gladiator Technologies’ low noise MEMS inertial sensor and systems technology coupled with VELOX™ high speed processing are now integrated with a 72 channel GNSS receiver to provide a compact GNSS – Inertial Navigation Systems (INS/GPS) for accurate position, velocity and attitude. The feature set was carefully selected to suit several PNT applications including flight control, navigation as well as 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 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.
Lee Dunbar, Chief Software Architect, commented that, “VELOX™ Technology combined with our new EKF enable our LandMark™ INS/GPS products incredible accuracy of less than 2 nautical miles per hour (NMPH) during short-term GPS outages. Our low noise sensor inputs to the EKF are enhanced by an innovation-based adaptive estimation algorithm. 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 a wide variety of 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.”
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.
