SECTION 1 INTRODUCTION 1.1 OVERVIEW The GARMIN GPS 35/36 is a complete GPS receiver, including an embedded antenna, designed for a broad spectrum of OEM (Original Equipment Manufacturer) system applications. Based on the proven technology found in other GARMIN 12 channel GPS receivers, the GPS 35/36 will track up to 12 satellites at a time while pr[...]

such as keyboards and displays are added by the application designer. 1.2 FEATURES The GPS 35/36 provides a host of features that make it easy to integrate and use. 1) Full navigation accuracy provided by Standard Positioning Service (SPS) 2) Compact design ideal for applications with minimal space 3) High performance receiver tracks up to 12 satel[...]

1.3.2 Environmental Characteristics 1) Operating temperature: -30°C to +85°C (internal temperature) 2) Storage temperature: -40°C to +90°C 1.3.3 Electrical Characteristics 1) Input voltage: 10 to 30 VDC, unregulated. 2) Typically draws 150 mA @ 12 VDC 3) Backup power: Internal 3V Lithium coin cell battery, up to 10 year life 1.3.4 Performance 1[...]

1.3.5 Interfaces 1) Dual channel RS-232 compatible with user selectable baud rate (1200, 2400, 4800, 9600) 2) NMEA 0183 Version 2.0 ASCII output (GPALM, GPGGA, GPGSA, GPGSV, GPRMC, GPVTG, PGRME, PGRMT, PGRMV, PGRMF, LCGLL, LCVTG) Inputs - Initial position, date and time (not required) - Earth datum and differential mode configuration command, alman[...]

SECTION 2 OPERATIONAL CHARACTERISTICS This section describes the basic operational characteristics of the GPS 35/36. Additional information regarding input and output specifications are contained in Section 4. 2.1 SELF TEST After input power has been applied to the GPS 35/36 and periodically thereafter, the unit will perform critical self test func[...]

6 Like all GPS receivers, the GPS 35/36 utilizes initial data such as last stored position, date and time as well as satellite orbital data to achieve maximum acquisition performance. If significant inaccuracy exists in the initial data, or if the orbital data is obsolete, it may take 5.0 minutes to achieve a navigation solution. The GPS 35/36 Auto[...]

The following modes are available: 1) 2D exclusively with altitude supplied by the host system (altitude hold mode) 2) 3D exclusively with altitude computed by the GPS 35/ 36 3) Automatic mode in which the board set determines the desired mode based on satellite availability and g[...]

fully automatic and, under normal circumstances, will take about 5 minutes to achieve a navigation solution. However, the host system should allow the GPS 35/ 36 to remain on for at least 12.5 minutes after the first satellite is acquired (see Section 4 for more information on status indications). 2) If the internal memory backup battery fails or i[...]
