11First Time FixThe first time you power up your new GPS 16, thereceiver must be given an opportunity to collect satellitedata and establish its present position. To ensure properinitialization, the GPS 16 is shipped from the factory inAutoLocate mode, which will allow the receiver to “finditself” anywhere in the world.Once the GPS 16 is installed and powered on, it willbegin to search for satellites. The GPS 16 will outputnavigation data once it has calculated an initial positionfi x. By default, the following data will be output inNMEA 0183, Version 2.0 format:• Latitude/Longitude/Altitude (GPGGA, GPRMC,GPGLL)• Velocity (GPRMC)• Date/Time (GPRMC)• Error Estimates (PGRME)• Satellite and Receiver Status (GPGSA, GPGSV,PGRMB, PGRMT)WAAS CapabilityThe GPS 16 is capable of receiving WAAS (WideArea Augmentation System) satellite signals. WAAS is anFAA (Federal Aviation Administration) funded project toimprove the overall accuracy and integrity of the GPSsignal for aviation use, but land/sea based users may alsobenefit from this system. At this time, the system is still inthe development stage and is not fully operational. Thereare currently two WAAS satellites that can be received inthe U.S.A., one over the Atlantic Ocean and one over thePacific Ocean, in a geo-stationary orbit over the equator.Effective use of the WAAS satellite signal may be limitedby your geographic location in relation to those satellites,now in developmental service. WAAS satellite signalreception requires an absolute clear view of the sky andworks best when there are no nearby obstructions suchas buildings, mountains, etc. WAAS satellites will benumbered 33 or higher when viewing the sky view onyour NMEA device. First-time use of the WAAS featuremay take up to 15-20 minutes to obtain differentialOperationUsing theGPS 16
