Disposing of Rechargeable Lithium-ion Battery
Discharge Lithium-ion battery before disposing of
it. When disposing of a battery, be sure to do so in
an environmentally sensitive manner. Adhere to any
local and national regulations concerning battery
disposal or recycling.
Receiver Use and Care
The receiver can withstand the rough treatment
that typically occurs in the field. However, the receiver is a high-precision electronic instrument and
should be treated with reasonable care.
CAUTION - Operating or storing the receiver out-
side the specified temperature range can damage
it. For more information, see Physical Specifications in this guide.
High-power signals from a nearby radio or radar
transmitter can overwhelm the receiver circuits.
This does not harm the instrument, but it can prevent the receiver from functioning correctly. Do not
use the receiver within 400 meters (1312 feet) of
powerful radar, television or other transmitters.
Low-power transmitters such as those used in cell
phones and two-way radios do not normally interfere with receiver operations.
For more information, contact your Spectra Precision distributor.
Bluetooth Radio
The radiated output power of the wireless radio is
far below the FCC radio-frequency exposure limits.
Nevertheless, the wireless radio shall be used in
such a manner that the Spectra Precision receiver
is 20 cm or further from the human body.
The internal wireless radio operates within guidelines found in radio-frequency safety standards and
recommendations, which reflect the consensus of
the scientific community. Spectra precision therefore believes the internal wireless radio is safe for
use by consumers.
The level of energy emitted is far less than the electromagnetic energy emitted by wireless devices
such as mobile phones. However, the use of wireless radios may be restricted in some situations or
environments, such as on aircraft. If you are unsure
of restrictions, you are encouraged to ask for authorization before turning on the wireless radios.
COCOM Limits
The US Department of Commerce requires that all
exportable GNSS products contain performance
limitations so that they cannot be used in a manner
that could threaten the security of the United
States.
The following limitation is implemented on the receiver: Immediate access to satellite measurements and navigation results is disabled when the
receiver’s velocity is computed to be greater than
1000 knots, or its altitude is computed to be above
17,000 meters (59,055 feet). The receiver continuously resets until the COCOM situation is cleared.

Introduction to Spectra Precision SP20
The Spectra Precision SP20 handheld GNSS receiver
combines innovative, camera-enabled data collection
workflow with a high level of performance in an ergonomic,
scalable solution from meter to centimeter accuracy.
Rugged and lightweight, the SP20 is easy to use and highly
accurate. It is the optimal tool not only for cadastral,
construction or topo surveys, but also for a range of GIS projects,
including data collection, inspection and maintenance.
The 5.3-inch screen delivers vivid visuals of the workflow,
which enables precise 2D handheld logging. And the system’s
high degree of accuracy can be enhanced with a monopole
accessory to deliver solid, survey-grade 3D measurements.
Whatever type of geospatial work you’re doing, turn to the easyto-use handheld that consistently delivers highly accurate results.
The SP20 key features are:
• Integrated, high-accuracy GNSS antenna and receiver
complete with all communication devices (cellular
modem, WiFi) for acquiring differential/RTK/Trimble RTX
corrections when needed.
• Ergonomic design: High-performance, high-accuracy data
collection in the palm of your hand.
• Powered by certified Android 6 Operating System. The
additional, specific Android applications required are:
– Spectra Precision SPace (available for free on Google
Play). This Android application is required to interface
SP20 with any third-party, standard Android
applications (such as Spectra Precision MobileMapper
Field) that make use of accurate positioning data as
input. SPace takes control of the Android mock
location parameter.
– Spectra Precision GNSSLoader (available for free).
This Android application is required to update the
GNSS firmware and install firmware or accuracy
options (with permanent or temporary validity).

• Handheld accuracy, position accuracy on demand. The
SP20 is available in different configurations providing
different position accuracies:
– Meter (default) (standalone GNSS+SBAS)
– Sub-meter (30/30)
– Decimeter (7/2)
– Centimeter (full RTK)
IMPORTANT NOTICE!
The SP20 is fitted with two distinct GNSS location providers:
•The u-blox Android GNSS
• The Spectra Precision high-accuracy GNSS module.
All location settings foun
GNSS, not the high-accuracy GNSS module.
When starting the SP20, by default both the Android GNSS
and the high-accuracy GNSS module are running. At this
stage, any application you will be using will receive lowaccuracy positions from the Android GNSS, and only from it.
High-accuracy positions will be available only if SPace – the
specific Spectra Precision mock location provider – is started.
SPace may be started manually, or automatically when
starting MobileMapper Field.
High-accuracy positioning will also be available for an
application supporting direct access to the high-accuracy
GNSS module. This will be the case with Spectra Precision
Survey Mobile (through TPSDK).
As soon as SPace, or any TPSDK-based application, is
started, the Android GNSS is made idle and the displayed
location settings in Android are all irrelevant.

GNSS Antenna
Height with
Monopole
When used on top of the monopole accessory (see picture; the
monopole adapter is secured to the back of the SP20, see
also page 3), the SP20 can deliver accurate vertical
coordinates because the monopole gives the SP20 excellent
vertical stability.
When the monopole is used, the antenna height (H) you need
to specify in your application (MobileMapper Field or Survey
Mobile) is the length of the monopole (read the graduation on
the monopole; see picture below).
For all Android applications using SPace as interface, and
when the monopole is used, you should enable Use monopole
on the SPace Settings screen.
The application will automatically add to H the distance (d)
from the base of the monopole adapter to the phase center so
that the application uses the real height of the GNSS antenna
phase center above the ground.

Turning On the
SP20
• Press the Power button [12] (see page 3) for a few
seconds until the SP20 vibrates, then release the button.
• Depending on how long your product was stored in its
package before being shipped to you, the remaining power
in the battery may be too low to allow the SP20 to operate
for your first working session. For this reason, the first
thing to do is to check the battery charge status:
– After the SP20 has started, read the battery icon in the
Android notification bar at the top of the screen. The
percentage of remaining charge is reported:
– If the remaining power is greater than 70%, then the
SP20 can be used for your first job. If it is less, Spectra
Precision recommends you first charge the battery as
explained below before you go to the field.

Attaching the
Handstrap
CAUTION - The ends of the
handstrap are different. One
is designed to be hooked to
the center bottom of the
unit, and the other to the
right or left side of the unit.
The SP20 can more safely be hand-held using the handstrap
(provided). The handstrap gives a better grasp and eliminates
the risk of accidentally dropping the unit to the ground.
First you should attach the two ends of the handstrap to the
back of the SP20. As shown below, there are two ways of
attaching it. You’ll choose one way or another, depending on
whether you are left- or right-handed.
English
Installing an
Accuracy Option
Before Running
Your GIS/Survey
Application
This step is required if you have purchased the SP20 with
position accuracy better than the default meter accuracy. You
need to download and install GNSSLoader on the SP20.
GNSSLoader can be downloaded for free from Google Play or
from the Spectra Precision website. For more information on
GNSSLoader, refer to page 24.
Most Android applications, including Spectra Precision
MobileMapper Field, will need SPace as the software
interface between your application and the SP20. SPace can
also be downloaded for free from Google Store/Google Play.
For more details, see Using SPace Software on page 10.
On the other hand, some other applications (like Spectra
Precision Survey Mobile) do not need SPace as they integrate
their own interface to the SP20.
Turning Off SP20 We recommend you neatly turn off the SP20 as explained
below, which will avoid losing data.
After you have finished your work, turn off the SP20 by
holding the Power button [12] pressed until a dialog pops up,
inviting you to either power off, reboot or switch the SP20 to
Airplane mode.
Touch Power off on the screen. This starts the power off
procedure. Wait until the screen goes blank.
9
Using SPace Software
English
SPace is the software interface required when running
Spectra Precision MobileMapper Field or a third-party
Android application on the SP20.
SPace is mainly used to:
• Forward positioning information from the SP20 high-
accuracy GNSS module to any application running on the
SP20 and using the Android mock location server.
• Process incoming corrections.
• Monitor both GNSS reception, corrections reception and
position accuracy.
Installing SPace
on your Mobile
Device
Starting SPace for
the First Time
SPace may be downloaded from Google Play (search for
“Spectraprecision” applications and then find “SPace” in the
list of available applications).
Follow the on-line instructions to install SPace on your SP20.
When launching SPace for the first time, a message will first
ask you to read and accept the EULA agreement. Another
message will follow asking you to choose the application
providing Android with position information:
Touch Yes. This will open the list of developer options. Scroll
down the screen until you find Select mock location app in the
Debugging section.
Touch Select mock location app. This opens a dialog listing the
apps that can be used for this purpose.
10
Touch SPace. The screen then shows that your choice is now
active.
Press to return to SPace (SKYPLOT tab displayed).
NOTE: You need to do this setting only once.
IMPORTANT- Whenever you launch SPace, including the first
time you do it, it takes about 4 seconds before the SP20 gets
initialized. During this time, the antenna icon in the SPace
status bar looks like this:
When initialization is complete, this icon changes aspect to
look like this:
English
Notes about the
User Interface
You will find the following graphic objects in SPace. The table
below explains what they are for and when and how to use
them:
Object Function
This is a switch: An empty circle stuck to the left means the concerned parameter is disabled while an orange circle stuck to the
right means it is enabled.
To switch from one state to the other, just touch the line including
this graphic object or simply drag the circle to the left or right.
This object is associated with the previous one. After making a
choice with the above switch, touch this button in the lower-right

SPace vs.
MobileMapper
Field
SPace vs. GNSS
Loader
SPace is started automatically when launching
MobileMapper Field. However only the section of SPace
delivering accurate positions will be run in this case. That
means SPace will actually work as a position server for
MobileMapper Field, but its own user interface will not be
running. The consequence is that SPace will not be seen by
Android as a running application.
NOTE: The SPace position server will be closed automatically
when quitting MobileMapper Field.
If you need to view what the current GNSS reception status
is while using MobileMapper Field, you will have to open the
SPace window to access this information. You may do this by
touching the SPace icon (below left) in the Android
applications menu, or by touching this icon (see below right)
in the Android notification bar:
To start GNSSLoader
successful only if SPace is NOT running, you will also have to
open the SPace window as indicated previously in order to be
able to quit SPace and then launch GNSSLoader.

How to Hold the SP20
In Your Hand This requires that you hold the SP20 in an appropriate
manner. The SP20 will have the best view of the sky if you
hold it at waist level (or higher), at such an angle that the top
of the unit (containing the GNSS antenna; see [1], page 3) is
in horizontal position and not too close to your body.
On Top of a
Mono-Pole
First attach the monopole adapter to the back of the unit. Use
a Philips screwdriver and the four screws provided to secure
the adapter. Mount the SP20 on top of the monopole
(optional accessory).
English
The SP20 will have the best view of the sky if you hold it not
too close to your body.
19
English
On a Pole With
External GNSS
Antenna
In cases where you wish to use an external GNSS antenna
mounted on top of a pole, the SP20 will be inserted into a
bracket (optional accessory) which you will fasten to the pole,
approximately at mid-height.
You can freely orientate the SP20 on its bracket since it is the
external GNSS antenna, and not the SP20’s own antenna,
that is used in this case.
Insert the SP20 into the bracket so that it is pinched where
you would normally hold it in your hand. That way you keep
the rear camera clear and preserve access to the Power
button.
You may use one of the two notches in the bracket to attach
the coaxial cable connecting the SP20 to the external GNSS
antenna (see above picture), thus protecting the coaxial
connector on SP20 side from wrenches.
To remove the SP20 from the bracket, hold the external jaw
of the bracket firmly in one hand and extract the SP20 from
the bracket using the other hand.

Usual Android Settings and More
Literature about Android 6 can easily be found on the
Internet. If you are new to Android, you may consult this
information on line. Below are suggestions of links you may
use to learn more about Android 6:
https://www.cnet.com/how-to/roasting-marshmallow-your-guide-to-android-6-0/
https://www.android.com/versions/marshmallow-6-0/
Many other sources of information exist on the Internet that
you can find by yourself.
This section only describes a few basic Android functions you
may need to use while working with your SP20.
English
Choosing the
Interface
Language
Setting Time & Date
• From the Android welcome screen, touch then .
• Scroll down to the Personal section and once visible, touch
the line containing this icon: .
• In the first field at the top of the screen, select your
language.
• Touch repeatedly to return to the Android
welcome screen.
Following a battery change in the field with no network
connection, the Android time & date is likely to be wrong
(because not automatically updated). Although as soon as
GNSS reception is re-established, raw data (if recorded) will
be properly time-tagged, the creation time and date will
remain incorrect.
If however you can temporarily get a WiFi or GSM connection
from your SP20, then you will allow the Android time & date
to be automatically updated.
But if this is not possible, we recommend you set the Android
time and date manually before resuming your work so that the
files you will subsequently create are all properly dated.
• From the Android welcome screen, touch then .
• Scroll down to the System section and once visible, touch
the line containing this icon: .
21
English
• Momentarily disable the Automatic date & time parameter
and then enter successively the current date and time in
the fields located underneath.
• Then re-enable the Automatic date & time parameter.
• Touch repeatedly to return to the Android
welcome screen.
Adjusting Time to
Screen Sleep
Mode
Assigning
Applications to the
Programmable
Buttons
When using your SP20 in the field, there may be long periods
of time during which your SP20 is collecting data but there
is no need for you to touch the screen during this time (for
example you are collecting a long line or polygon feature with
MobileMapper Field). In this case you may want to keep the
screen awake throughout the logging sequence.
The default time for the screen to switch to sleep mode being
only 1 minute of inactivity, you will probably want to change
this time. Here is how you can do this:
• From the Android welcome screen, touch then .
• Scroll down to the Device section and once visible, touch
the line containing this icon: .
• Touch the fourth field (Sleep) and then choose the
duration of inactivity at the end of which the screen will
turn blank. The longest time you may choose is 30
minutes of inactivity.
• Touch repeatedly to return to the Android
welcome screen.
NOTE: The fact that the screen switches to sleep mode has
no impact whatsoever on any data collection sequence taking
place in the SP20.
(See programmable buttons A and B on page 3.)
• From the Android welcome screen, touch then .
• Scroll down to the Personal section and once visible, touch
the line containing this icon: (AB Key Set).
• Touch key A or B at the top of the screen then tick one of
the apps listed below that you want to assign to this key
(e.g. Calculator). Repeat this action for the other key if you
wish (e.g. E-compass).
• Touch repeatedly to return to the Android
welcome screen.
22
Resetting SP20 In the very unlikely case where your SP20 would stop
responding and a press on the power button would have no
effect, then you might conveniently use the reset button for a
fresh restart of the unit without having to temporarily remove
the battery.
The reset button is that miniature button nested close to the
USB connector (see [7] on page 3). To press this button use
a thin, long and pointy tool, like for example a pencil or an
unfolded paper clip.
After pressing the button, the SP20 will simply restart. This
action has no effect whatsoever on your Android settings, your
applications, files and personal data. It’s just a hardware
reset.
English
23
Using GNSS Loader
English
This application is required whenever you need to update the
SP20’s GNSS firmware and/or if you have purchased the
SP20 with better than one meter position accuracy.
GNSSLoader will be used in the latter case to install the
corresponding firmware option.
GNSSLoader can be downloaded for free from the spectra
Precision website or from Google Play at:
https://play.google.com/store
Follow the instructions to install GNSSLoader on your SP20.
Then run GNSSLoader by touching this icon on the Android
home screen:
The GNSSLoader menu includes the following functions:
• Reset GNSS: Touch this option to reset the SP20’s built-in,
high-accuracy GNSS receiver. When the sequence is
complete, this message is displayed:
Complete
GNSS has been reset to the default settings
Touch OK to close the message dialog box and return to
the main menu.
• Upgrade firmware: Opens a window listing the possible
GNSS firmware upgrades currently stored in the Download
folder. These files use the following naming convention:
SP20_upgrade_vx.xx.x.tar
Where vx.xx.x is the firmware version contained in the upgrade file.
24
(So you should have downloaded your GNSS firmware
upgrade from the Spectra Precision website to the
Download folder before using the Upgrade firmware
function.)
To install an upgrade select the file and then touch .
• Install accuracy option: Opens a window listing the currently
installed accuracy options.
The ADD button located at the bottom of the screen allows
you to add a new option by entering the corresponding
POPN. The following screen appears after touching ADD:
If you have purchased your SP20 with sub-meter,
decimeter or centimeter accuracy, you should have
received the corresponding POPN via email.
Enter the POPN and touch INSTALL.
• Install service or other option: Same as Install accuracy option.
This function needs a passcode, which is used to activate
a Trimble RTX service for which you have purchased a
subscription.
English
• About: Returns the software version of your GNSSLoader
application, the SP20 unit serial number and the software
version of the GNSS firmware currently installed in your
SP20. Touch OK to return to the main menu.
NOTE: GNSSLoader cannot be started while SPace is
running. If you try to do so, a message will appear informing
you that this is not possible.
