Page 5: Introduction
INTRODUCTION 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 16/17 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 16/17. -
Page 6: Limited Warranty
Garmin retains the exclusive right to repair or replace the unit or software or offer a full refund of the purchase price at its sole discretion. SUCH REMEDY SHALL BE YOUR SOLE AND EXCLUSIVE REMEDY FOR ANY BREACH OF WARRANTY. -
Page 7: Overview
OEM (Original Equipment Manufacture) system applications. Based on the proven technology found in other Garmin 12-channel GPS receivers, the GPS 16/17 tracks up to 12 satellites at a time while providing fast time-to-first-fix, one-second navigation updates, and low power consumption. This generation of GPS sensors adds the capability of FAA Wide Area Augmentation System (WAAS) differential GPS. -

Page 16: Software Interface
The GPS 16/17 series products interface protocol, in addition to transmitting navigation information as defined by NMEA 0183, transmits additional information using the convention of Garmin proprietary sentences. Binary phase data information can alternatively be output on the COM 1 port; see... -
Page 17: Sensor Initialization Information
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. -
Page 18: Additional Sensor Configuration Information (Pgrmc1)
0183 sentence transmission will be suspended temporarily. 5. $PGRMO,,G will cause the COM port to change to Garmin Data Transfer format for the duration of the power cycle. You must enable Garmin Data Transfer format to update the GPS 16/17 series products. -
Page 19: Tune Dgps Beacon Receiver (Pslib)
4.1.6 Tune DGPS Beacon Receiver (PSLIB) The $PSLIB sentence provides the ability to tune a Garmin GBR 21, GBR 23 or equivalent beacon receiver. $PSLIB,<1>,<2>*hh<CR><LF> <1> Beacon tune frequency, 0.0, 283.5–325.0 kHz in 0.5 kHz steps <2> Beacon bit rate, 0, 25, 50, 100, or 200 bps If valid data is received, the GPS sensor will store it in the EEPROM and echo the PSLIB command to the beacon receiver. -
Page 20: Transmitted Time
4.2.2 Transmitted Time The GPS sensor outputs UTC (Coordinated Universal Time) 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. -

Page 30: Appendix C: Ephemeris Data Download (Programming Example)
To download the ephemeris data, you must first command the unit to output information in Garmin Binary Format (Garmin mode) instead of the default NMEA output format. To put the unit in Garmin mode, connect to the unit using a terminal program and send the following NMEA sentence: $PGRMO,,G*hh<CR><LF>... -
Page 31: Ephemeris Download Procedure
Ephemeris Download Procedure The following is the sequence of events that occurs when downloading ephemeris. Send a packet containing the command that requests ephemeris data (IOP_DOWN_LOAD_EPH). The packet should look like this: TX Packet: Ephemeris Data Request Byte Description Name HEX Value Delimiter 0x10... -
Page 32: Rx Packet: Ephemeris Data
Next, the unit will send the specified number of packets containing the ephemeris information. An example packet is shown below. Each packet should be acknowledged as before (be sure to modify the ACK packet to indicate what type of packet being acknowledged—for ephemeris data, the ID is 0x35). RX Packet: Ephemeris Data Byte Description Name... - Page 33 An example function to do the parsing is shown below. Note that the double data types are converted by the function cnvt_ieee_double(). This function merely swaps the upper and lower words of the double. This is necessary on GPS 15, 16, 17 series sensors due to a compatibility issue with the IEEE floating point standard): In this example, the array m_TempArray contains the data portion of the ephemeris packet (with DLE stuffing removed).
-
Page 34: Tx Packet: Download Complete
Each data member of the ephemeris data structure is indexed into the data array of the ephemeris packet and cast as the appropriate data type. The indices are as follows (note that they correlate to the data members of the structure respectively): #define IDX_EPH_WN #define IDX_EPH_TOC... -
