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

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

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 I

2

C port.

UART

The UART ports can be used for sending data and receiving commands.
