Using GNSS Loader

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 in the Android

applications menu:

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.

(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 install a new option after entering the

corresponding POPN.
