11First Time FixThe first time you power up your new GPS 17, thereceiver must be given an opportunity to collect satellite dataand establish its present position. To ensure proper initializa-tion, the GPS 17 is shipped from the factory in AutoLocatemode, which will allow the receiver to “find itself” anywherein the world.Once the GPS17 is installed and powered on, it willbegin to search for satellites.The GPS 17 will output naviga-tion data once it has calculated an initial position fix. Bydefault, the following data will be output in NMEA 0183,Version 2.0 format:• Latitude/Longitude/Altitude (GPGGA, GPRMC)• Velocity (GPRMC)• Date/Time (GPRMC)• Error Estimates (PGRME)• Satellite and Receiver Status (GPGSA, GPGSV,PGRMB, PGRMT)WAAS CapabilityThe GPS 17 is capable of receiving WAAS (Wide AreaAugmentation System) satellite signals. WAAS is an FAA(Federal Aviation Administration) funded project to improvethe overall accuracy and integrity of the GPS signal for avia-tion use, but land/sea based users may also benefit from thissystem. At this time, the system is still in the developmentstage and is not fully operational.There are currently two WAAS satellites that can bereceived in the U.S.A., one over the Atlantic Ocean andone over the Pacific Ocean, in a geo-stationary orbit over theequator. Effective use of the WAAS satellite signal may belimited by your geographic location in relation to those satel-lites, now in developmental service. WAAS satellite signalreception requires an absolute clear view of the sky andworks best when there are no nearby obstructions such asbuildings, mountains, etc. WAAS satellites will be numbered33 or higher on the sky view on your NMEA device.OperationUsing theGPS 17
