English GNSS Antenna Height with Monopole d H Optional Accessories 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.
Unpacking The following items are delivered in the box: • SP20 unit • Li-Ion battery • Universal power adapter (includes a USB-to-micro-USB cable) • Quick Start Guide • 2 x screen protectors • Monopole adapter (an attachable 5/8-inch female adapter + 4 x Philips head screws) • Handstrap • Battery door opener (a black, rigid pen-shaped accessory) • Pouch. NOTE: Spectra Precision reserves the right to make changes to this list without prior notice.
English 4. Put the battery door away. 5. If you are using a SIM card or/and a Micro SD card, insert these items now, BEFORE inserting the battery, making sure these are oriented as instructed on the label, contact side facing down for each of them. Insert the SD card first, then the SIM card. [1] [2] CAUTION: For a micro or nano SIM card, please use a rigid, not a flexible SIM card adapter. Flexible SIM card adapters may damage the SIM card slot. 6. Insert the battery as shown below.
8. Then push the battery door against the unit and lock it. 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.
English Using the Universal Power Adapter to Charge the Battery Follow the instructions below. • Prepare the power adapter: – Choose the plug that fits your country’s AC outlet standard (see [1]). [1] [2] 2] – Slide it into the AC adapter [2]. (A “click” must be heard when fully inserted.) • Take the USB cable provided [3]. • Connect the end fitted with a standard USB connector to the power adapter.
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. CAUTION - The ends of the handstrap are different.
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 highaccuracy 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.
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: Notes about the User Interface You will find the following graphic objects in SPace.
English Setting SP20 to Receive Corrections After the SP20 has initialized, do the following to set it up (see also SPace Settings on page 13 to have a global view of all the settings you can make in SPace): • In the status bar, touch . • Touch the Correction Information field. You are then requested to choose between different sources of corrections: Source of corrections SBAS NTRIP DIP RTX IP RTX L-BAND Meaning Corrections will be received from an SBAS satellite.
NOTE: Next time you turn on the SP20 for a new working session, the last NTRIP or DIP network connection made will be re-established automatically, provided you still have the required environment (modem, Wi-Fi) to establish a network connection. SPace Settings • In the status bar, touch . • Set the following parameters: – Autostart application at boot: Enabling this parameter means SPace will be started automatically next time you power on your SP20.
English – Receiver (a read-only field): Displays the product name (“SP20”). – Correction Information: Source of corrections currently used. If you touch this line, you may change the type of connection through which corrections enter the SP20 (SBAS, NTRIP, DIP, RTX IP or RTX L-BAND; see page 12 for all the details). By touching the “+” symbol after selecting “NTRIP” or “DIP”, you may add a new NTRIP or DIP provider respectively.
– Keep NMEA outputs running: When enabled, this option makes sure all the NMEA messages delivered by the GNSS receiver to SPace continue to be output while SPace is running and after SPace has stopped running. – Help: Touch this line to open the Help page. Use the Back key on the SP20 to close the Help page. – About: Touch this line to read the installed SPace software version.
English Touch Legend ([4]) to read the color convention used for each constellation to represent satellite locations on the skyplot view: In the lower part of the screen, you can read the total number of currently tracked satellites and total number of satellites currently used.
• Status: Network connection status (Connected or Disconnected) (Blank if SBAS). Receiver Profile Status : Touch this icon (see [5] on page 15) to read information about the SP20: • Receiver Type: “SP20”. • GNSS Connection Status: “Connected” necessarily. At power up, as long as this connection is not active, you cannot open this window. The receiver icon then looks like this: NOTE: After launching SPace, it takes about 4 seconds before this connection is active.
English – 30/30 (sub-meter accuracy): Accuracy is 30 cm in both horizontal and vertical. • RTX Option: Indicates whether a Trimble RTX subscription is valid (“CenterPoint RTX” or FieldPoint RTX” is displayed) or not (“None” is displayed). NOTE: RTK options may have temporary validity (1 month). Settings See page 13. External GNSS Antenna : This icon (see [7] on page 15) is shown only if an external GNSS antenna has been connected to the SP20 (see plug [10] on page 3).
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 Monopole First attach the monopole adapter to the back of the unit. Use a Philips screwdriver and the four screws provided to secure the adapter.
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.

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.
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.
English 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.
