ETLG Ltd (Inertial Aerosystems) announces a new product to our Magnetics range, with an upgrade to the current Dead Reckoning Module. The Honeywell DRM4000L offers the perfect solution for personnel on foot to provide continuous, gap-free, position location, with or without an external GPS, to provide the user’s position relative to an initialization point.
The Honeywell DRM4000L replaces the DRM4000, and offers improved performance and reliability, and a reduced power consumption from 350mW to 250mW.
The introduction of 3 digital rate gyros in a single package to replace the previous 3 single analog rate gyros design and improved manufacturing processes mean that a single PCB board can be used instead of the previous 3 board design, leading to a significant reduction in both size and weight.
When GPS data is available, the dead reckoning sensors are automatically calibrated continuously, when GPS is unavailable, the gyros, accelerometers, magnetometers, temperature and barometric altimeter sensors of the dead reckoning module are used to determine position. Patented motion classification algorithms (SmartPedometry™) allows the unit to distinguish between walking, running, side stepping, and walking backwards. A barometric altimeter provides vertical positioning, accurate to 1.5m, enough to discriminate between different floors in a building.
With horizontal accuracy of 2% of distance travelled, independent of time and 1o compass azimuth accuracy with resolution 0.1o.
An optional Development kit includes an enclosure complete with GPS receiver and antenna plus interfaces and development software.
