Sparton Navigation and Exploration debuts GPS-assisted inertial navigation system

ORLANDO, Fla., 14 May 2014. Sparton Navigation and Exploration (NYSE:SPA) is introducing GAINS-10, its GPS/GNSS Assisted Inertial Navigation System, at AUVSI 2014.

GAINS-10 provides accurate inertial navigation in the presence of mechanical shock, transient platform vibrations, and extreme magnetic interference, officials say. It features high-speed, synchronous sampling of all inertial systems combined with high-rate coning and sculling compensation and is calibrated across temperature.

“The GAINS-10 delivers precise performance in complex environments,” says Jim Lackemacher, group vice president of Sparton’s Defense & Security Engineered Products. “Sparton’s GAINS-10 provides flexible integration options and platform customization.”

GAINS-10 features include:

• Advanced EKF implementation coupled with Sparton’s proprietary AdaptNav sensor fusion algorithms

• Multi-GNSS receiver module using multiple satellite constellations in parallel

• 10 DOF High Performance Inertial Measurement Unit

• Enhanced MEMS sensing technology (3-axis magnetic, 3-axis acceleration, 3-axis gyro and barometer)

• High speed synchronous sampling of all inertial sensors

• Customizable on-board high speed digital filtering

• Sculling and coning compensation

• High-speed data logging capability to off-board µSD card

• Ruggedized, shockproof design, with proprietary seals that allow barometric pressure sensing combined with IP67 performance

• Low power consumption with power-management functionality (Sleep Mode)

• Interface to external GPS receiver

• External data interface via Multi-GPIO connectivity

• Powerful user programmable customizations via NorthTek Forth interpreter
