CELogGPS is a SIO-CalCOFI Windows program that records cruise events and activities timestamped with GPS date-time-lat-lon. Other notable events such as marine mammal-avifauna sightings, CUFES, or any data-generating activity may also be recorded. The GPS position can be ingested basically two ways:
- On UNOLS vessels with MET, the MET (meterological system) string provides GPS data. A workstation is setup to run MetCapture, another SIO-CalCOFI program, that collects the MET data and appends event numbers when updated. METCapture saves the current MET string (with GPS date-time-lat-lon) to a file (currpos.csv) on the shipboard data network that all eventlogging workstations can harvest. Please review the METCapture documentation for more info. (Standard GPS input is acceptable; METCapture can log GPS instead of MET data or the GPS feed may be connected directly to the CELogGPS tablet serial port.)
- On NOAA vessels, a USB GPS (current model: GlobalSat BU-353 USB GPS Receiver with SiRF Star III based Serial GPS receiver with WAAS/EGNOS support for enchance position accuracy) is attached directly to the CELogGPS tablet and provides the GPS data (currpos.csv) to the shipboard data server and other networked eventloggers. See the GPS settings section below for setup information.
