MC-1108-G
Standalone multiple GNSS module
0.1
Introduction
LOCOSYS MC-1108-G is a complete standalone GNSS module. The module can simultaneously
acquire and track multiple satellite constellations that include GPS, GLONASS, GALILEO, QZSS and SBAS.
It features low power and small form factor. Besides, it can provide you with superior sensitivity and
performance even in urban canyon and dense foliage environment.
This module supports hybrid ephemeris prediction to achieve faster cold start. One is self-generated
ephemeris prediction (called EASY) that is no need of both network assistance and host CPU’s intervention.
This is valid for up to 3 days and updates automatically from time to time when GNSS module is powered on
and satellites are available. The other is server-generated ephemeris prediction (called EPO) that gets from an
internet server. This is valid for up to 14 days. Both ephemeris predictions are stored in the on-board flash
memory and perform a cold start time less than 15 seconds.

5.3 Examples to configure the power mode of GNSS module
The GNSS module supports different power modes that user can configure by issuing
software commands.
5.3.1 Standby mode
User can issue software command to make GNSS module go into standby mode that
consumes less than 500uA current. GNSS module will be awaked when receiving any byte.
The following flow chart is an example to make GNSS module go into standby mode and
then wake up.

5.3.3 AlwaysLocateTM mode
AlwaysLocateTM is an intelligent controller of periodic mode. Depending on the
environment and motion conditions, GNSS module can adaptively adjust working/standby
time to achieve balance of positioning accuracy and power consumption. In this mode, the
host CPU does not need to control GNSS module until the host CPU needs the GNSS
position data. The following flow chart is an example to make GNSS module go into
AlwaysLocateTm mode and then back to normal operation mode.

include time interval, distance, speed, logging mode, and … etc. For more information, please
contact us.
5.5 Examples to configure the update rate of GNSS module
The GNSS module supports up to 10Hz update rate that user can configure by issuing
software commands. Note that the configurations by software commands are stored in the
battery-backed SRAM that is powered through VBACKUP pin. Once it drains out, the
default/factory settings will be applied.
Due to the transmitting capacity per second of the current baud rate, GNSS module has to
be changed to higher baud rate for high update rate of position fix. The user can use the
following software commands to change baud rate.
Baud rate
Software command
Factory default
$PMTK251,0*28<CR><LF>
4800
$PMTK251,4800*14<CR><LF>
9600

$PMTK251,57600*2C<CR><LF>

Note: <CR> means Carriage Return, i.e. 0x0D in hexadecimal. <LF> means Line Feed, i.e. 0x0A in
hexadecimal.
If the user does not want to change baud rate, you can reduce the output NMEA sentences
by the following software commands.

After the GNSS module is changed to higher baud rate or reduced NMEA sentence, the
user can configure it to high update rate of position fix by the following commands.
Interval of position fix
Software command
(1)
Every 100ms (10Hz)
$PMTK220,100*2F<CR><LF>
Every 200ms (5Hz)
$PMTK220,200*2C<CR><LF>

Every 1000ms (1Hz)
$PMTK220,1000*1F<CR><LF>
(2)
Every 2000ms (0.5Hz)
$PMTK220,2000*1C<CR><LF>
If the command is correct and executed, GNSS module will
output message $PMTK001,220,3*30<CR><LF>
Note 1: The minimum interval of position fix is 100ms, i.e. the maximum update rate is 10Hz.
Note 2: The current consumption is the same with the update rate of 1Hz.
5.6 Configure the static navigation parameter
The output position of GNSS module will keep the same and output speed will be zero if
the actual speed is below the threshold of the static navigation parameter. This is useful for
different applications. For example, the car stopped at a red light will get stationary GNSS
position if the threshold is 1.5m/s. It is better to disable this function by setting threshold to 0 for
pedestrian navigation.
The format of the software command is as below.
$PMTK386,speed threshold*checksum<CR><LF>
The unit of speed threshold is meter per second. The range of speed threshold is from
0.1m/s to 2.0m/s. Value 0 is to disable the function.

Active at “L” input. Internal pulled up via a resistor. If this
pin is not used, leave it floating.
<Note>
1.
In order to get the advantage of hybrid ephemeris prediction, this pin must be always powered during the period of
effective ephemeris prediction.

Note 1. This happens when downloading AGPS data to MC-1108-G.
Note 2. Measured when position fix (1Hz) is available, input voltage is 3.3V and the function of self-generated ephemeris
prediction is inactive. For different input voltage, the current consumption is as below chart. This is because MC-1108-G
has a built-in DC/DC converter.
