1 INTRODUCTION 1.1 CAUTION CAUTION The GPS system is operated by the government of the United States, which is solely responsible for its accuracy and maintenance. Although the GPS 16x is a precision electronic NAVigation AID (NAVAID), any NAVAID can be misused or misinterpreted, and therefore become unsafe. Use these products at your own risk. To reduce the risk, carefully review and understand all aspects of these Technical Specifications before using the GPS 16x. When in actual use, c

4 SOFTWARE INTERFACE The GPS 16x series products interface protocol design on COM 1 is based on the National Marine Electronics Association’s NMEA 0183 ASCII interface specification. The COM 2 port can receive differential GPS (DGPS) correction data using the Radio Technical Commission for Maritime Services’ RTCM SC-104 standard. These standards are fully defined in NMEA 0183, Version 3.0 (copies may be obtained from NMEA, www.nmea.org) and RTCM Recommended Standards For Differential Navsta

4.1.2 Sensor Initialization Information (PGRMI) The $PGRMI sentence provides information used to initialize the GPS sensor’s set position and time used for satellite acquisition. Receipt of this sentence by the GPS sensor causes the software to restart the satellite acquisition process. If there are no errors in the sentence, it will be echoed upon receipt. If an error is detected, the echoed PGRMI sentence will contain the current default values. Current PGRMI defaults (with the exception o

4.1.4 Additional Sensor Configuration Information (PGRMC1) The $PGRMC1 sentence provides additional information used to configure the GPS sensor operation. Configuration parameters are stored in non-volatile memory and retained between power cycles. The GPS sensor will echo this sentence upon its receipt if no errors are detected. If an error is detected, the echoed PGRMC1 sentence will contain the current default values. Current default values can also be obtained by sending $PGRMC1E to the

4.2 TRANSMITTED NMEA 0183 SENTENCES The subsequent paragraphs define the sentences that can be transmitted on COM 1 by the GPS sensor. 4.2.1 Sentence Transmission Rate Sentences are transmitted with respect to the user selected baud rate. The GPS sensor will transmit each sentence (except where noted in particular transmitted sentence descriptions) at a periodic rate based on the user selected baud rate and user selected output sentences. The GPS sensor will transmit the selected sentences

4.2.2 Transmitted Time The GPS sensor outputs Coordinated Universal Time (UTC) date and time of day in the transmitted sentences. Before the initial position fix, the on-board clock provides the date and time of day. After the initial position fix, the date and time of day are calculated using GPS satellite information and are synchronized with the one-pulse-per- second output. The GPS sensor uses information obtained from the GPS satellites to add or delete UTC leap seconds and correct the
