Abstract
The document presents the results of a performance analysis of a LCPOS configured with heading aiding from a GPS attitude sensor. The inertial and GPS data used in the analysis were recorded during the Endeavor sea trials in November 1994. The LCPOS configuration analyzed during a previous contract identified here as LCPOS Phase 1 using the same data included only GPS position and velocity aiding from a Trimble TASMAN P/Y-code GPS receiver. This work included in addition heading aiding data from a Trimble TANS Vector GPS attitude sensor. The results of this analysis have demonstrated that the addition of heading aiding from a GPS attitude sensor handles the heading accuracy deficiency encountered in the Phase 1 work. The LCPOS handles GPS attitude aiding outages with almost negligible impact on 3-axis attitude accuracy. The LCPOS handles complete GPS outages lasting up to 5 minutes with almost no degradation in 3-axis attitude accuracy. Position accuracy degradation over 1 minute outages is acceptable but can become quite large over 20 minute outages. This work has demonstrated that LCPOS with GPS heading aiding is cost-effective alternative to a costly ship INS for the purpose of measuring a ship's position and 3-axis attitude.
