4. PRODUCT FEATURES
Multi-Constellation Navigation (SL869-V2 and SL869L-V2 only)
GPS and GLONASS constellations are enabled by default. Enabling BeiDou disables GLONASS
and Galileo.
The user may enable or disable constellations via the $PMTK353 command
The SL869-V2S and SL869L-V2S support GPS only.
Quasi-Zenith Satellite System (QZSS)
The satellites of the Japanese regional SBAS are in a highly inclined, elliptical geosynchronous orbit,
allowing continuous high-elevation coverage over Japan using only three satellites plus one
geostationary satellite. PRNs 193, 194, and 195 are supported. They provide ranging signals for
augmentation of the GPS system.
QZSS constellation usage is controlled by the $PMTK352 command and is disabled by default.
NMEA reporting for QZSS may be enabled/disabled by the $PMTK351 command.
Satellite-Based Augmentation System (SBAS)
SBAS is not supported on the current production SL869L-V2S and SL869-V2S modules (with the
enhanced ROM).
The receiver is capable of using SBAS satellites as a source of differential corrections. These
systems (WAAS, EGNOS, GAGAN and MSAS) use geostationary satellites to transmit signals
similar to those of GPS in the same L1 band.
Enabling the SBAS feature limits the maximum fix rate to 5 Hz. If disabled, the maximum is 10 Hz.
The module is enabled for SBAS by default, but can be disabled by command PTMK313.
Either SBAS or DGPS corrections can be used and are selected by the PMTK301 command.
SBAS is not supported on the SL869L-V2S or the SL869-V2S with enhanced ROM (from Oct 2015).
SBAS Corrections
The SBAS satellites transmit a set of differential corrections to their respective regions. The use of
SBAS corrections can improve positioning accuracy
Differential GPS (DGPS) (SL869L-V2 and SL869L–V2S only)
DGPS is a Ground-Based Augmentation System (GBAS) for reducing position errors by applying
corrections from a set of accurately-surveyed ground stations located over a wide area. These
reference stations measure the range to each satellite and compare it to the known-good range. The
differences can then be used to compute a set of corrections which are transmitted either by radio
to a DGPS receiver or over the internet.
The DGPS receiver can then send them to the module 2
104 protocol message types 1, 2, 3, and 9.
nd
serial port (RX2) using the RTCM SC-
These corrections can significantly improve the accuracy of the position reported to the user.
The receiver can accept either the RTCM SC-104 messages or SBAS differential data via command
PMTK501.

Assisted GPS (AGPS)
Assisted GPS (or Aided GPS) is a method by which TTFF is improved (reduced) using information
from a source other than broadcast GPS signals.
The necessary ephemeris data is calculated either by the receiver itself (locally-generated
ephemeris), or a server (server-generated ephemeris) and stored in the module.
Please refer to Section 2.3 Product Variants for applicability.
Locally-generated AGPS - Embedded Assist System (EASY)
This feature is not supported on the SL869-V2S until ROM MT3337E version (enhanced) of Oct
2015. It is supported on the SL869L-V2S.
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 three 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.
EASY is disabled if the fix rate is > 1 Hz
EASY is on by default, but can be disabled by command PMTK869.
Server-generated AGPS - Extended Prediction Orbit (EPO)
(SL869-V2 and SL869L-V2 only)
Server-based ephemeris predictions are maintained on Telit AGPS servers. 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 local broadcast ephemeris collection, and are valid for up to
14 days.
Note that the EPO data stream does not conform to the NMEA-0183 standard.
Please refer to the Telit EPO Application Note for details.
Example source code is available under NDA.
Contact TELIT for support regarding this service.
Please refer to the next section regarding EPO support (Host EPO) on the SL869-V2S and SL869LV2S.
Host EPO
The SL869-V2S and SL869L-V2S do not have flash memory. However, they can still make use of
Assisted GPS. If the system design includes a host processor, it can access server-generated EPO
data and send it to the module over the primary serial port. This data is valid for six hours. Host EPO
data is not retained over a power cycle.
Note that the EPO data stream does not conform to the NMEA-0183 standard.
Please refer to the MT333x Host EPO Application Note.
Contact Telit support for further details.
10 Hz Navigation
The default rate of 1 Hz can be changed by command PMTK500 to a maximum of 10 Hz.
Enabling the SBAS feature limits the maximum fix rate to 5 Hz.
The SL869-V2S and SL869L-V2S maximum is 5 Hz.
Elevation Mask Angle
The default elevation mask angle is 5°. It can be changed via the PMTK311 command.

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 unfrozen when the speed increases above a threshold or when the
computed position exceeds a set distance (10 m) from the frozen position (indicating that the receiver
is again in motion). The speed threshold can be set via the PMTK386 command.
Set this threshold to zero to disable static navigation.
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 $PMTK386.
Jamming Rejection – Active Interference Cancellation (AIC)
The receiver module detects and removes narrow-band interfering signals (jamming signals) without
the need for external components or tuning. It rejects up to 12 CW (Continuous Wave) type signals
of up to –80 dBm (total power signal levels). This feature is useful both in the design stage and
during the production stage for uncovering issues related to unexpected jamming. When enabled,
Jamming Rejection will increase current drain by about 1 mA, and impact on GNSS performance is
low at modest jamming levels. However, at high jamming levels (e. g. –90 to –80 dBm), the RF signal
sampling ADC starts to become saturated after which the GNSS signal levels start to diminish.
Jamming rejection is enabled by default, but can be disabled with the PMTK286 command.

Internal LNA (SL869L-V2 and SL869L-V2S only)
The SL869L-V2 and SL869L-V2S modules include a built-in LNA to increase sensitivity.
1PPS
The module provides a 1PPS output signal.
Please refer to Section 9.3.5.1 1PPS for detailed information.

Power Management Modes
The receiver supports operating modes that reduce overall current consumption with less frequent
position fixes. Availability of GNSS signals in the operating environment will be a factor in choosing
power management modes. The designer can choose a mode that provides the best trade-off of
navigation performance versus power consumption.
The various power management modes can be enabled by sending the desired command using the
host serial port (RX).
Table 4-1 Power Management - Command summary
Full Power Continuous Mode
The module starts in full power continuous mode when powered up. This mode uses the acquisition
engine to search for all possible satellites at full performance, resulting in the highest sensitivity and
the shortest possible TTFF.
The receiver switches to the tracking engine to lower the power consumption when:
• A valid GPS/GNSS position is obtained
• The ephemeris for each satellite in view is valid
To return to Full Power mode from a low power mode, send a $PMTK225,0*2B
command just after the module wakes up from its previous sleep cycle.
If power is removed from both Vcc and Vbatt, then Time, Ephemeris, Almanac, EASY, EPO data,
and PMTK configuration data will be lost. If Vbatt is present, no data will be lost.

Standby Modes
In these modes the receiver stops navigation, the internal processor enters the standby state, and
the current drain at main supply VCC_IN is substantially reduced.
STOP: ARM baseband, RF, and TCXO are powered down
SLEEP: ARM baseband and RF are powered down
To enter a Standby mode, send the following command:
$PMTK161,0*28 (STOP Mode)
$PMTK161,1*29 (SLEEP Mode)
To exit a Standby mode, send any byte to the host port (RX).
GLP Mode (SL869-V2 and SL869L-V2 only)
In the GNSS Low Power (GLP) mode, power consumption is reduced for some time during a one
second period. The module will alternate this cycling with periods of full power when necessary, for
example weak signals or decoding the navigation message.
A typical current draw is 10 to 14 mA, depending on conditions.
Note that position accuracy will be reduced during GLP operation, therefore the user must
determine the tradeoff between power consumption and desired accuracy.
A timeline is shown below:
Figure 4-2 GNSS Low Power (GLP) mode diagram
To enter the GLP mode, send the command:
$PMTK262,3
To exit the GLP mode and return to full-power mode, send the command:
$PMTK262,0
