navbe > Navigational Location and Attitude Best EstimateVAP Type(s) > Evaluation

The Navigation Best Estimate (NAVBE) VAP was developed in response to the 2012–2013 Marine ARM GPCI Investigation of Clouds (MAGIC) deployment, the first ship-based deployment of the second ARM Mobile Facility (AMF2). It has since been applied to the 2015 ARM Cloud Aerosol Precipitation Experiment (ACAPEX) deployment and the 2017–2018 Measurements of Aerosols, Radiation, and Clouds over the Southern Ocean (MARCUS) field campaign. A number of instruments on the ships collected Global Positioning System (GPS) and Inertial Navigation System (INS) measurements during MAGIC. The motivation of the NAVBE VAP is to consolidate many different sources of this information in a single, continuous datastream to be used when information is required about ship location and orientation and to provide a more complete estimate than would be available from any one instrument. The result is 10 Hz and 1-minute datastreams reporting ship position and attitude.
