The MobileMapper 300 packout consists of the following
items:
•[1]: MobileMapper 300 GNSS receiver
•[2]: Universal AC/DC adapter shipped with four different
types of input connectors.
•[3]: Power cable extension (male jack to 6-pin connector)
•[4]: Vehicle power cable (cigarette lighter connector type
to female jack)
•[5]: Soft transport bag.
• + MobileMapper 300 Quick Start Guide (not shown)
Optional Accessories
Two brackets for 7” or 10” tablets.
Cable Kit P/N 91865-00 (see picture). This kit is used to
establish a USB connection between the MobileMapper 300
and a computer. This connection is required for upgrading the
GNSS firmware when the computer has no Bluetooth.
Because the process takes 15-20 minutes, the
MobileMapper 300 should always be connected to external
power when updating firmware.
The optional cable kit therefore consists of:
•
A V-shaped cable terminated with a DB9-f connector. One
of its other ends is fitted with a female jack, for connection
to a power source, and the other with a 6-pin circular
connector for connection to the MobileMapper 300
.
• A short cable extension (USB to DB9-m), to be used
between the computer (USB port) and the V-shaped cable
(SubD-9m).

Charging the
Batteries
Before using your new MobileMapper 300, Spectra Precision
recommends you first charge its batteries in your office.
1. Unpack the AC/DC adapter. Slide the button as shown in
picture a to release the cap protecting the input contacts.
2. Of the four input connectors provided, choose the one that
matches the type of electric outlet used in your country.
Insert it as shown in picture b. You can hear a “click”
when the input connector gets fastened to the power
adapter.
3. Plug the jack end of the power cable extension to the AC/
DC adapter cable, then connect its other end to the Power/
Data connector on the MobileMapper 300.
4. Plug the AC/DC adapter to an electric outlet. Battery
charging starts immediately in standard charging mode.
The Power/Charging LED will first turn solid green for a
few seconds and then will blink red at a slow rate (every
3 seconds approximately).

5. Wait a few hours until the batteries are fully charged. End
of charging is denoted when the Power/Charging LED goes
out.
6. Disconnect the AC/DC adapter from the MobileMapper
300. Put the cap back in place to protect the Power/Data
connector during field operations.
NOTE: The MobileMapper 300 may be left on the AC/DC
adapter indefinitely without damage.
Getting Started 1. Thread the MobileMapper 300 onto a range pole.
2. Attach the mobile device bracket to the pole.
3. Attach the mobile device to the bracket.
4. Turn on the MobileMapper 300 by holding the Power
button depressed for about 2 seconds.
Check the status of the Power/Charging LED, which
should blink red and green slowly while the MobileMapper
300 is being started (this takes about 20 seconds).
After the MobileMapper 300 has started, the Power/
Charging LED turns solid green meaning the
MobileMapper 300 is now functioning and ready for use.
At the same time, the Bluetooth LED will start flashing
blue at a rate of approximately 1 second, meaning that the
MobileMapper 300 is ready to accept a Bluetooth
connection.
5. Turn on the mobile device.
6. Run SPace to first establish a Bluetooth connection with
MobileMapper 300, and then to choose and set the
transmission channel (i.e. SBAS, NTRIP or DIP) through
which corrections will enter the MobileMapper 300. (see
instructions in Setting MobileMapper 300 to Receive
Corrections on page 6).
7. Using SPace, check that MobileMapper 300 delivers
accurate positions.
8. Run your GIS application. SPace will continue to run in
the background.
Reading the
Battery Status
At any time while using the MobileMapper 300, you can
monitor the remaining charge in the two built-in batteries by
reading the status of the Power/Charging LED:
• Solid green: remaining charge is greater than 20%.
• Blinking green: remaining charge is less than 20%.

English

Using SPace Software
SPace is the Spectra Precision software dedicated to
interfacing MobileMapper 300 with your mobile device. This
application is mainly used to:
• Connect your mobile device to the MobileMapper 300 via
Bluetooth.
• Connect your mobile device to a corrections provider via
the built-in modem or Wi-Fi, or allow SBAS tracking (for
SBAS corrections).
• Monitor GNSS and corrections reception.
• Check position accuracy.
Installing SPace
on your Mobile
Device
SPace may be downloaded from Google Play (search for
“Spectraprecision” applications and then find “SPace” in the
list of available applications). Then follow the instructions to
install the application on your mobile device.
Making
MobileMapper
300 the “Position
Provider”
It is essential that the position solution used by your GIS
application be the one coming from MobileMapper 300, and
not from the mobile device’s built-in GNSS chip. This is
achieved by enabling the Allow Mock Locations (1) option in
your Android device. You need to do this once, through the
following procedure:
• First activate Developer options in your Android device as
explained below:
– Tap on the Settings icon and then on About device.
Depending on the type of device used, the About device
menu is accessible either directly through the Settings
menu, or through the General sub-menu. It may also
have a different name (About, About tablet, About
phone...).
– Tap seven (7) times on the Build number menu item. A
message will indicate that the Developer options are
now active.
• Escape from the About device menu. The Developer options
item is now visible in the Settings menu.
1.The term “Mock location” is somewhat misleading and inappropriate here, as it designates the option that
lets MobileMapper 300 deliver high-accuracy positions to your application. Originally this option was probably
designed for test purposes (through which mock position messages from a simulator could be delivered to the
Android device). With MobileMapper 300, it is the same option that allows you to benefit from a much more
accurate position that the built-in GNSS chip could ever provide, which the name of this option does not reflect
at all.

English

• Tap on Developer options and then check on Allow mock
locations. From now on, MobileMapper 300 will be the
position provider for your application.
Setting
MobileMapper
300 to Receive
Corrections
• Make sure MobileMapper 300 is on and the blue LED is
blinking.
• Run SPace on your mobile device.
• Read and accept the EULA agreement. (This is requested
only the first time you run SPace.)
This automatically starts a search for other Bluetooth
receivers located nearby (Scanning for Receivers Nearby). All
visible Bluetooth receivers are listed at the end of the
search. The Bluetooth identifier for a MobileMapper 300
is of the type: “MM300xxxxxxxx”.
• Touch the Bluetooth identifier corresponding to your
MobileMapper 300. The mobile device then initiates a
Bluetooth connection with the MobileMapper 300
(Establishing connection with receiver). When this
connection is established, the Bluetooth LED on the
MobileMapper 300 will turn solid blue, “Receiver
Connected” will be reported on the mobile device screen
along with a small green padlock appearing further to the
right in the MobileMapper 300 Bluetooth identifier line.
NOTE: Some mobile devices may require the
MobileMapper 300 Pin Code the first time you make a
Bluetooth connection. In this case, enter “1234”.
• Touch the right arrow to continue.
• If needed, enter the antenna height (i.e. rod length).
Entering this height will cause the system to compute the
height of the corresponding ground point as the z
coordinate of every position it will deliver.
NOTE: Later on touch (top of the screen) and edit the
Antenna Height (in meters) parameter if for some reason you
need to change the antenna height.
• Touch the right arrow to continue. You are then requested
to choose between four different sources of corrections:
–SBAS
–NTRIP
– DIP (Direct IP)
– RTX. This choice requires a valid subscription to the
Tri mble CenterPoint RTX service.
Check the current status of your RTX subscription on the
Receiver Profile Status view by tapping .

English

• Choose the desired source of corrections, and then touch
the horizontal right arrow in the lower-right corner of the
screen.
1. If you chose SBAS: The message Setting up application
will appear briefly, followed by the SKYPLOT view (see
below).
2. If you chose NTRIP: The first time you want to make
an NTRIP connection, there is no predefined
connection profile available. Touch the “+” symbol in
the lower-left corner of the screen and then enter the
parameters of your NTRIP provider:
Host Name or IP Address
Friendly Name (max 20 chars)
Port Number
Touch the Get Source Table button to list the mount
points available from this provider and select one. If
you remember the name of the mount point you want
to use, you don’t need to acquire the source table: Just
touch the Enter Mount Point button and type in the name
of the desired mount point.
Then enter your NTRIP credentials (User Name and
Password).
Touch Connect at the bottom of the screen. At this
point, SPace will initiate a network connection to allow
the MobileMapper 300 to receive corrections from the
chosen NTRIP provider. The message “Please Wait” will
appear, followed by another message “Setting up
application”. Then the SKYPLOT view will be displayed
(see below).
3. If you chose DIP: The first time you want to make a DIP
connection, there is no predefined connection profile
available. Touch the “+” symbol in the lower-left
corner of the screen and then enter the parameters of
your DIP provider:
Host Name or IP Address
Friendly Name (max 20 chars)
Port Number
Touch Connect in the lower part of the screen. At this
point, SPace will initiate a network connection to allow
the MobileMapper 300 to receive corrections from the
chosen static IP address. The message “Please Wait”
will appear, followed by another message “Setting up

application”. Then the SKYPLOT view will be displayed
(see below).
4. If you chose RTX: The message Setting up application
will appear briefly, followed by the SKYPLOT view (see
below).
NOTE: Next time you turn on your mobile device and
receiver for a new working session, the last NTRIP or DIP
network connection made will be re-established
automatically, provided the MobileMapper 300 is within
Bluetooth range, is not already connected to another
Bluetooth device, and you’ve got the required environment
(modem, Wi-Fi) to establish a network connection.

Battery Charging Modes
The built-in batteries may be charged using one of two
charging modes:
•Standard charging: This is the default mode used when
you connect a power source to the MobileMapper 300.
The batteries will be fully charged after about 8 hours of
charging. This is the recommended charging mode to
preserve the capacity of the batteries over time. Typically,
you will charge the batteries at the end of your work day
so that you will have a fully charged system the next
morning. (The MobileMapper 300 has a typical operating
time of 10 hours.)
•Fast charging: The MobileMapper 300 will switch from
standard to fast charging mode by briefly pressing the
Power button. The batteries will get charged in just 3
hours.
Fast charging should not be considered as the normal
charging mode, but rather as an emergency mode. Should
you run out of batteries while working in the field, then
you can select that mode to charge the batteries quickly,
for example from your vehicle’s battery (see also below).
NOTE: Reversing to standard charging mode when fast
charging is on can only be made by unplugging the power/
data cable and plugging it back.
Different power sources may be used, depending on where
you are when the batteries need to be re-charged:
• In the office, use the universal AC/DC adapter and the
power cable extension to charge the MobileMapper 300
batteries (see picture).
• In the field, use the vehicle cigarette lighter adapter and
power cable extension. Warning! Use this only with a 12V
vehicle!

English

The batteries will be charged typically while the
MobileMapper 300is off. However, charging is also possible
with the MobileMapper 300 on. Watch the Power/Charging
LED to read the current battery charging status (see table
below).

button. The Power/Charging LED starts blinking red and
green, as it would do on a normal start-up, but this time
for about 25 seconds.
• At the end of the reset sequence, the MobileMapper 300
will stay powered and the Power/Charging LED will turn
solid green.
