Overview The SL869 represents a new age of receiver that can simultaneously search and track satellite signals from multiple satellite constellations. This multi-GNSS receiver uses the entire spectrum of GNSS systems available: GPS, GLONASS, Galileo and QZSS. Operation in a high interference signal environment is common practice in today’s electronic age. By incorporating 3-stage rejection architecture, the SL869 is able to remove interfering signals pre- and post-correlation. Operating on a single 3.3V power supply, this module combines a GNSS engine, TCXO, SAW Filter, RTC and LDO. Communication is done over a UART serial port using NMEA message format. The SL869 shares the same form factor as the Telit Jupiter JN3 and SL869 V2 families, 16mm x 12.2mm, commonly used in the industry. The SL869 product family; SL869, SL869-T and SL986-DR offers default configurations to meet specific market needs. As a the Standard GNSS Module, the SL869 offering high sensitivity, low power consumption, jamming immunity and fast time to first fix. As a Timing Module, the SL869-T provides best-in-class timing performance with an extremely stable synchronized 1PPS output and TRAIM (Time-Receiver Autonomous Integrity Monitor) integrity monitoring. As a DR Module, the SL869-DR receiver provides the user with accurate estimates of vehicle’s position and velocity when GNSS information is lost or not available by combining speed and heading sensor data into the solution. The result is improved navigation in harsh urban canyon environments. Reproduction forbidden without written authorization from Telit Communications S.p.A. - All Rights Reserved.

ANTENNA VBATT VCC 1.8V Reg RTC TCXO GNSS LNA Flash SAW I2C 1PPS UART/USB/CAN Figure 1 SL869 Architecture Note: LNA is included in the GNSS chip for passive antenna operation. 3.2. Major Components All power supply components are on board including capacitors. 3.2.1. GNSS Chip This single chip GNSS device includes an integrated Baseband and RF section. The LNA amplifies the GPS signal and provides enough gain for the receiver to use a passive antenna. A very low noise design is utilized to provide maximum sensitivity. Flash memory is integrated so external memory is not required. 3.2.2. RF_IN This GNSS RF signal input supports both active and passive antennas. An external BIAS-T and antenna voltage supply are required for an active antenna. Reproduction forbidden without written authorization from Telit Communications S.p.A. - All Rights Reserved.

The SL869 includes a switching voltage regulator that supplies 1.8V to the GNSS device. 3.2.4. VBATT The Battery Backup supply voltage is 2.5V to 3.6V. It is a typical low current supply for ensuring that the RTC is kept running and critical data is maintained to enable HOT/WARM starts. 3.2.5. Serial Interface The SL869 host serial port is the primary communications port which outputs data and accepts commands in NMEA format. 3.2.6.  Main Serial Interface: Standard asynchronous RX/TX 8-bit protocol on pins 20 & 21.  Secondary Serial Interface: Normally not used, but can be utilized for RTCM differential corrections into the receiver. If debug is enabled, the debug data is output on this port.  Tertiary Serial Interface: Hardware controlled through USB_DETECT on pin 7. This port is only used as a USB Port. See the HW User Guide for more details. SAW Filter This filters the GNSS signal and removes unwanted signals caused by external influences that would corrupt the operation of the receiver. The integrated LNA outputs to the SAW filter which then feeds the GNSS receiver. 3.2.7. TCXO This highly stable 26 MHz oscillator controls the down conversion process for the RF block. 3.2.8. RTC The 32 KHz Real Time Clock allows Hot/Warm starts. 3.2.9. Memory The SL869 has an integrated 2Mbyte Flash device for operational software and satellite data storage. 3.3. Physical Characteristics The SL869 receiver has advanced miniature packaging with a base metal of copper and an Electro less Nickel Immersion Gold (ENIG) finish. It has a tin-plated shield and 24 interface pads. These pads are castellated edge contacts.

TTFF (Time to First Fix) TTFF is the actual time required by a GPS receiver to achieve a valid position solution. This specification will vary with the operating state of the receiver, the length of time since the last position fix, the location of the last fix, and the specific receiver design. Please refer to section 4.8 for performance data. 4.1.1. Hot Start A hot start results from a software reset after a period of continuous navigation, or a return from a short idle period (i.e. a few minutes) that was preceded by a period of continuous navigation. In this state, all of the critical data (position, velocity, time, and satellite ephemeris) is valid to the specified accuracy and available in memory. 4.1.2. Warm Start A warm start typically results after a period of continuous navigation is followed by an extended period of continuous RTC operation with an accurate last known position available in memory. In this state, position and time data are present and valid but ephemeris data validity has expired. 4.1.3. Cold Start A cold start acquisition results when either position or time data is unknown. Almanac information is used to identify previously healthy satellites. 4.2. AGPS GPS aiding, also known as Assisted GPS (AGPS), is a method by which TTFF is reduced using information from a source other than broadcast GPS signals. The form of assisted GPS data supported and used by the module is predicted ephemeris data. Ephemeris predictions is a method of GPS aiding that effectively reduces the TTFF through the use of predicted ephemeris data as a substitute for broadcast ephemeris data to produce a navigation solution. In this way, every start is potentially a hot start. There are two sources of predicted ephemeris – locally predicted ephemeris and server-based predicted ephemeris data. 4.2.1. Local AGPS Proprietary algorithms within the module perform ephemeris prediction locally from captured broadcast ephemeris data from tracked satellites. The algorithms predict ephemeris for up to five days. Reproduction forbidden without written authorization from Telit Communications S.p.A. - All Rights Reserved.

Server-Based AGPS Server-based ephemeris predictions are generated by a third party and are maintained on Telit AGPS servers in a file. The predicted ephemeris file is obtained from the AGPS server and is injected into the module over the Host port. These predictions do not require local broadcast ephemeris collection, and they are valid for up to seven days. The module supports server-based AGPS as standard. Contact TELIT for support regarding this service. 4.3. Time Mark Pulse (1PPS) For standard SL869 modules, a 1PPS time mark is output whenever the receiver has a navigation fix of 2D fix or better. For SL869-T timing modules, the 1PPS time mark pulse is output all the time. The 1PPS output at a 50% duty cycle, has a default pulse width of 500ms. 4.4. Differential Aiding The module supports differential GPS (DGPS) operation. DGPS improves position accuracy by correcting GPS signal errors caused by ionospheric disturbances as well as timing and satellite orbit errors. 4.4.1. Satellite Based Augmentation Systems (SBAS) The SL869 is capable of receiving WAAS, EGNOS, and MSAS satellite differential corrections, which are regional implementations of SBAS for North America, Europe, and Eastern Asia, respectively. 4.4.2. RTCM The SL869 accepts RTCM SC-104 standard differential corrections data, which are typically received by an RTCM radio beacon receiver. RTCM corrections are accepted over a serial port. The module supports message types 1 and 9. Reproduction forbidden without written authorization from Telit Communications S.p.A. - All Rights Reserved.

Reduced Power Modes The SL869 supports operational modes in that allow it to provide positioning information at reduced overall current consumption. 4.5.1. Adaptive Channel Management The SL869 supports an adaptive channel management algorithm which dynamically switches off a GNSS constellation and reduces the number of tracked satellites when conditions allow. 4.5.2. Duty Cycling The SL869 supports power cycling of the RF chain such that satellites are tracked for shorter periods of time between positioning updates. 4.6. Timing The SL869-T (Timing Module) provides an independent and highly accurate 1PPS output, synchronized to GNSS time or UTC within
