Implementation of the DREO (Defence Research Establishment Ottawa) PLANS (Primary Land Arctic Navigation System) Experimental Development Model

摘要

The sensors chosen for PLANS are all commercially available, and they fall into two categories: the self contained dead reckoning (DR) sensors and the external aiding sensors. The primary self contained sensors are the vehicle odometer and a gyro unit. The external aiding sensors are satellite positioning systems, which rely on radio transmissions from the Transit or GPS satellites. This report gives a brief background summary of the PLANS development program, and provides a general description of the DREQ Experimental Development Model (XDM) of a Primary Land Arctic Navigation System (PLANS). The report includes a generic description of the essential PLANS hardware requirements (processors, memory, interfaces, displays, sensors etc.) as well as the specific hardware used in the XDM. A high level description of the software structure and data flow is given. A brief general description of the salient functional characteristics of PLANS is presented, including the accuracy performance. Also provided is an extensive list of references for further detailed information on the various components of the PLANS XDM. (FR)
