QUANTAHM.1.2
2.2.2. External sensors
2.2.2.1. Odometer
In addition to the GNSS aiding, the Quanta Land series include an odometer input which can greatly improve
performance in challenging environments such as urban canyons. The odometer provides a reliable velocity
information even during GPS outages. This increases significantly the dead reckoning accuracy.
Quanta series handle quadrature output or compatible odometers in order to support forward and backward
directions.
Note: Odometer integration is made really simple as the Kalman filter will finely adjust odometer's gain
and will correct residual errors in the odometer alignment and lever arm.
2.3. System Performance
All specifications are rated to 1 , over -40°C to +85°C (-40 to
σ
185°F) unless otherwise stated.
These specifications have been measured based on typical mission scenarios with simulated GPS outages and
compared to post processed RTK data of a high end FOG based INS.
For each application, the accuracy parameters are defined in different positioning modes, explained below:
●
SP refers to Single Point mode and is the default fix quality
●
RTK stands for Real Time Kinematics with a typical 1 cm position accuracy
●
PPK is the post-processed accuracy with a base station, providing a 1cm position accuracy.
