Overview
The XS1110 is a receiver that is capable of tracking GPS and GLONASS systems
simultaneously. This module provides an external antenna interface that supports
passive GNSS antennas.
The XS1110 is one of the smallest multi-GNSS modules on the market with an ultra-
compact size of 6.7 x 7.0 x 2.1 mm in a QFN package. It supports multiple interfaces
such as I2C that can be used instead of UART.
The module is integrated with a low drop out LDO which allows for the lowest possible
power consumption while offering optimum GNSS sensitivity and performance.
The XS1110 is based on the latest Sony CXD5605GF chipset and supports all
standard GNSS features including QZSS, Anti-Jamming, and AGPS.

Precautions
Important: Please read carefully before you start.
If you use the GNSS receiver inside buildings, tunnels, or beside any huge
objects, the GNSS signals might be cut off or weakened. Please do not assume
the receiver has malfunctioned.
This document provides the necessary guidelines for a successful system design
using the XS1110 module. For detailed module specifications, refer to this guide.
The XS1110 is an electrostatic-sensitive device; please DO NOT touch the
module directly. Follow ESD safety rules when handling. When using the XS1110
for the first time, it is strongly recommended that you test the module outdoors
with open sky, for at least 12 minutes and 30 seconds, to ensure receiving the
complete navigation message.
System Block Diagram
Figure 1-1: System Block Diagram
I2C
The I2C interface is a serial input and output port, operating as a slave device.
•Slave receiving
•Slave address: 0x24
•Speed grades: Standard-mode 100 kbit/s, Fast-mode 400 kbit/s

Function Description
Rev 4.0 Jul.20 9 41113354
1PPS
The XS1110 generates a one pulse-per-second signal (1PPS) after 3D fixed. It is
an electrical signal which precisely indicates the start of a second within an
accuracy of 25 ns. The PPS signal is provided through a designated output pin for
additional applications.
LLE for Fast TTFF
The LLE provides pre-download proprietary ephemeris data to speed up TTFF.
This feature is useful when a satellite signal is weak or when there is no signal; it
allows for the module to get position information quickly. LLE can be downloaded
from an FTP server via the Internet. LLE injection type can support GPS,
GLONASS, Galileo, BeiDou and QZSS.
SGE
The SGE is for quick positioning by itself when information received from the
satellites is sufficient. When SGE is enabled, the XS1110 will automatically
calculate and then predict single ephemeris up to three days. The predicted
information will be saved into the memory and the XS1110 will then use the saved
information for later positioning. The valid duration of SGE data is three days.
PVT Logger Function
The PVT logger function is enabled in the XS1110 module, and allows for the
module to become a logger-capable (built-in internal flash) device and record
GNSS data such as UTC, latitude, and longitude; it helps with record logging for
debugging.
The external flash of the module has 4.8 KB for this function and uses the smart
overlapping mechanism to keep the latest logger data.
Normal Mode
In Normal mode, the XS1110 module keeps on operating normally and updates
the latest navigation message anytime to get an accurate positional information.

Product Technical Specification
Rev 4.0 Jul.20 10 41113354
Low Power Tracking
Figure 1-3: Power Consumption in Low Power Tracking
When low power tracking of XS1110 is enabled, in the beginning, it keeps
receiving a GNSS navigation message. This GNSS navigation message is
continually received for about 12 minutes and 30 seconds and includes the
ephemeris, almanac, and satellite health in open sky.
After that, the module runs to cycle between Sleep (15 secs) and Exec (30 secs)
as shown in Figure 1-3.
Before the XS1110 module enters into a sleep state, it outputs
"GNSSLOWP,ENTRY,OK" messages in NMEA sentences to indicate that sleep
mode will be executed. Once the XS1110 wakes up, it outputs "GNSSLOWP,
WAKEUP, OK" to indicate that the module has woken up and will start updating
the navigation message.
The module executes hot start internally after waking up every time, then it
acquires satellite information for about 30 seconds to update the TOW (time of
the week).The module will check all of the satellite ephemeris status and ensure
that all updated data is the latest. Once update is complete, the modules enters
into the sleep cycle. If it doesn’t, it will keep acquiring satellites in an exec status
until all the navigation messages are completely updated as this is helpful for
ensuring positional accuracy.
The module will hot start after waking up from an intermittent behavior and, within
30 seconds, track satellites to update the TOW (time of the week). Then the
module will check all of the satellite ephemeris to ensure data update is complete.
If there are no issues, the module gets into the next sleep cycle. Otherwise, the
module will switch into continuous operation and keep tracking until data update
is complete.

·For RX0 pin: UART 0 receiver; to receive commands from the system.
·For I2C_SDA pin: It can transceiver data and communicate with host.
Note: UART signals are named with respect to Module and directions are listed with
respect to the module. For example, UART_RX0 is an output from the Host to the module.
UART_TX0 is an output from the module to the Host.
• Pin14: 1PPS
This pin provides a one pulse-per-second signal output. If not used, keep this
pin floating.
• Pin15: NRESET
Active on Low for the module to reset. If not used, keep this pin floating.
Table 2-3: BOOT MODE Pin Setting
Mode Function
Normal (Floating) The module automatically enters normal mode by default.
BootROM (Pull high) Enter Boot ROM mode to upgrade by firmware using these
steps, when the module does not work normally or the upgrade
fails:
1. The WAKEUP pin must be initially connected to “VCC”.
2. Power on the module’s main power.
3. Use “SWGNSSTool’ to upgrade the firmware.
4. The BOOT MODE pin can be removed from “VCC” when
the upgrade process is completed.
5. Push the NRESET button to reset the module and allow it
to boot up normally.
