4. PRODUCT FEATURES
4.1. Multi-Constellation Navigation
GPS and GLONASS constellations are enabled by default.
The user may enable or disable GPS, GLONASS, Galileo, and BDS constellations via
command. GLONASS and BeiDou cannot be enabled simultaneously.
4.2. Quasi-Zenith Satellite System (QZSS) Support
The satellites of the Japanese SBAS are in a highly inclined geosynchronous orbit,
allowing continuous coverage over Japan using only three satellites plus one
geostationary satellite. The signals may be used for ranging. QZSS ranging is disabled by
default but can be enabled by command.
4.3. Satellite Based Augmentation System (SBAS)
The receiver is capable of using SBAS satellites both as a source of differential
corrections and satellite ranging measurements. These systems (WAAS, EGNOS, GAGAN
and MSAS) use geostationary satellites to transmit regional corrections via a GNSS-
compatible signal.
4.3.1. SBAS Corrections
The SBAS satellites transmit a set of differential corrections to their respective regions.
The use of SBAS corrections can improve positioning accuracy.
4.3.2. SBAS Ranging
The use of SBAS satellites can augment the number of measurements available for the
navigation solution, thus improving availability and accuracy.
4.4. Assisted GPS (AGPS)
A GNSS receiver requires ephemeris data to calculate the precise position in space of
each satellite to be used in the navigation solution. Since the satellites move at a speed
of 3874 km/s along their orbits and are subject to gravitational perturbations from all
masses in the solar system, this data must be both current and accurate. Each GPS
satellite transmits a complete set of its ephemeris coefficients (called the broadcast

SL869-V3 Product User Guide
1VV0301217 Rev. 6 Page 15 of 62 2021-03-31
ephemeris or BE) every 30 seconds. This is therefore the minimum time required for a
cold start Time to First Fix (TTFF). The BE data is usually refreshed every 2 hours.
The minimum cold start TTFF can be reduced from 30 seconds to just a few seconds by
enabling AGPS, which can provide Extended Ephemeris (EE) data by two methods -
•Locally generated: The receiver includes software to project the future positions
of the satellites. This data may be calculated out to 14 days or even longer,
depending on the resources available in the receiver, e.g. computation
ability and memory.
•Server-generated: A server calculates the future position projections and makes
them available to a receiver, typically over the internet. This data may be
good for 30 days, depending on available resources, e.g. communication
links and storage.
This Extended Ephemeris (EE) data is then stored for use at the next restart and can
reduce cold start times to a few seconds.
If server-generated EE data is received and processed, locally generated data is not used.
AGPS is enabled by default but can be disabled by command.
4.4.1. Locally generated AGPS (ST-AGPS)
Proprietary algorithms within the module perform GPS ephemeris prediction locally from
stored broadcast ephemeris data (received from tracked satellites). The algorithms
predict orbital parameters for up to 5 days. The module must operate in Full Power mode
for at least 5 minutes to collect ephemeris data from visible satellites, or 12 hours for the
full constellation.
4.4.2. Server-generated AGPS (PGPS/PGLO)
Telit AGPS servers maintain calculated extended ephemeris data. The predicted
ephemeris file is obtained from the AGPS server and is transmitted to the module over
serial port 1 (RX). These predictions do not require collection of broadcast ephemeris,
and are valid for up to 14 days.
Server-based AGPS is supported as a standard feature.
An Application Note and example source code are available under NDA.
Contact TELIT for support regarding this service.

SL869-V3 Product User Guide
1VV0301217 Rev. 6 Page 16 of 62 2021-03-31
4.5. Differential GPS (DGPS)
Differential corrections can be supplied to the module from an RTCM beacon receiver.
RTCM SC-104 Ver. 2.3 messages 1, 9 and 31 (both GPS and GLONASS) are supported.
The module will indicate Differential mode when corrections are supplied.
The use of DGPS corrections can substantially improve position accuracy.
By default, DGPS is disabled.
4.6. Static Navigation
Static Navigation is an operating mode in which the receiver will freeze the position fix
when the speed falls below a threshold of 0.3 m/s (indicating that the receiver is
stationary).
The course and altitude are also frozen, and the speed is reported as “0”.
The navigation solution is updated every 40 seconds while the receiver is in the Static
Navigation mode.
The navigation solution is unfrozen when the speed increases above the threshold or
when the computed position exceeds a set distance from the frozen position (indicating
that the receiver is again in motion).
This feature is useful for applications in which very low dynamics are not expected, the
classic example being an automotive application.
Static Navigation is disabled by default but can be enabled by command.
4.7. Elevation Mask Angle
The default elevation mask angle is 5°. It can be changed by command.
4.8. 10 Hz Navigation
The default rate of 1 Hz can be changed by command to a maximum of 10 Hz.
4.9. Internal LNA
The module includes a built-in LNA to improve sensitivity.

SL869-V3 Product User Guide
1VV0301217 Rev. 6 Page 17 of 62 2021-03-31
4.10. 1PPS
The module provides a 1PPS output signal whenever the receiver has a valid fix (2D or
3D).
The pulse is approx. 500 ms
4.11. Antenna Enable
The Antenna Enable output can be used to control an external power supply to an active
antenna (or external LNA). It will be high when the receiver is operating, or low when it is
in a low-power (standby) mode.
4.12. Antenna Sense
The Antenna Sense feature measures the current consumed by the external LNA or
active antenna and reports its status as NORMAL, SHORTED, or OPEN in an NMEA
proprietary message.
4.13. Serial I/O Ports
The module includes three serial ports and an I2C port.
4.13.1. UART
The UART ports can be used for sending data and receiving commands.
See section 8.8.1 UART Port Operation.
4.13.2. I2C
By default, the I2C port is not assigned an I/O function.
Refer to section 8.8.2 I2C Port Operation.
