PRODUCT FEATURES
GPS (L1 C/A) and NavIC (L5) Navigation
GPS and NavIC (formerly IRNSS) constellations are enabled by default.
Satellite Based Augmentation System (SBAS)
The receiver is capable of using SBAS (GAGAN) satellites as a source of differential corrections.
These systems use geostationary satellites to transmit regional corrections via a GNSS-compatible
signal.
SBAS Corrections
The SBAS satellites transmit a set of differential corrections to their respective regions. The use of
SBAS corrections can improve positioning accuracy.
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 ephemeris or BE) every 30 seconds. This is therefore the minimum
timerequiredfor 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
implementing AGPS, which can provide Extended Ephemeris (EE) data by two methods -
1. 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.
2. 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.
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.
Server-generated AGPS (PGPS)
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.

SL869T3-I Product User Guide Product Features
1VV0301546 r0 Page 17 of 57 2018-11-09
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.
Static Navigation
Static Navigation is an operating mode in which the receiver will freeze the position fix when the
speed falls below a set threshold (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 a 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.
Elevation Mask Angle
The default elevation mask angle is 5°. It can be changed by command.
Internal LNA
The module includes a built-in LNA to improve sensitivity.
1PPS
The module provides a 1PPS output signal whenever the receiver has a valid fix (2D or 3D).
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.
Antenna Sense
The Antenna Sense feature measures the current consumed by the external LNA or active antenna
and reports its status as NORMAL, SHORT, or OPEN in an NMEA proprietary message.
Serial I/O Ports
The module includes three serial ports and an I2C port.
UART
The UART ports can be used for sending data and receiving commands.
See section 8.8.1 UART Port Operation.
