1) Upgrading to U-blox 1.30 Firmware
The default firmware version of the HERE + modules is ublox-1.10 firmware. The new
version of 1.30 firmware includes new feature of fusing other satellite systems (Glonass /
beidou) with GPS for RTK operations, effectively increasing the RTK positioning accuracy.
Therefore, it is recommended that all users upgrade to 1.30 firmware before using HERE+.
During the preparation of this guide, ublox-1.40 version of the firmware has also been
released. 1.40 version firmware introduced a new feature called the mobile base station,
that is, the base station need not be fixed in a location. For example, a base station may be
placed on a moving vehicle or boat. Upgrading to Ublox-1.40 version is similar to upgrading
to 1.30. For users who do not need to use the mobile baseline feature, upgrading to version
1.30 is sufficient.
a) Downloading U-centre UI and 1.30 Firmware
Upgrading firmware requires the use of Ublox's Windows software U-center. To download
U-center, please go to the official website link: https: //www.u-blox.com/en/product/u-
center-windows. Then follow the prompts to install U-cent software. During the installation
process, you will be prompted to install the device Driver, please ensure that only the
Standard Driver For Windows is checked, as shown below.
You will also need to download firmware at: https://www.u-
blox.com/en/search?keywords=HPG+1.30. Click the choice: u-blox M8 Flash Firmware 3.01
HPG 1.30 - ONLY for High Precision GNSS products.

b) Connect your HERE+ Base and Rover to Computer
When upgrading the base station module, use the USB cable to connect the base station
module to the computer USB interface, as shown in the following figure:
When upgrading a Rover module, use a hexagonal screwdriver to open the case. The rover
module has a USB interface connector identical to the base module, you can use the base
module USB cable to connect rover to computer. In addition, during the firmware upgrading
process, the rover module needs to be powered by connecting to flight controller, as shown
in the following figure:

c) Upgrading Process
Open the U-center software, click the connection button (as shown in the red circle), select
the com port that corresponds to your base/ rover module.
Click tools->u-blox 5 –8 Flash Firmware Update, and click the settings as shown below:

6
In Firmware image, unzip and select the downloaded 1.30 Firmware.For base module,
chose the firmware with title:
UBX_M8_301_HPG_130_REFERENCE_NEOM8P2.59a07babb501ba6a89ff87cac2f 2765f.bin
For rover module, choose the firmware:
UBX_M8_301_HPG_130_ROVER_NEOM8P0.3ee86a9e4775e3335e742b53527fa5 d0.bin
In Flash Information Structure(FIS) File, select Flash.xml，which is located in the installation
address of U-centre software.

7
Click OK and wait for the firmware uploading to complete. Uploading usually takes only a
minute or less. If the uploading is successful, the upgrade interface is displayed in green; if
the upgrade is aborted, the interface is displayed in red. If the process is interrupted, or if it
is not responding for a long time, the modules will need to be power cycled and uploading
needs to be done again.

d) Check current Rover/Base firmware version
When base/rover is already connected to U-centre, click View, go to Message View -> UBX
-> MON -> VER, you will see the interface below:
As shown in the figure, the current firmware version is FWVER = HPG 1.30 REF, indicating
that the current firmware version is 1.30 for base module.

2) Basic Operating Manual
a) Use Mission Planner for Base module surveying/ Rover module positioning
This part of the tutorial uses Mission Planner ground control software and Arducopter-3.5
flight control firmware for operating instructions. If you are using PX4 firmware and
QGroundControl ground station software, please refer to the link:
https://docs.px4.io/en/advanced_features/rtk-gps.html 。
i) Preparation before Operation
To use HERE + on a UAV, you need the following hardware:
Before using, make sure the hardware is connected correctly:
The base station module is connected to the computer port through USB; a telemetry
module is connected to another USB port of the same computer.
For UAV, HERE + rover module is connected to the flight controller GPS connector,
telemetry module is connected to the TELEM interface.

During operation, please place the base station in an outdoor environment with sufficient
sky coverage to obtain a good satellite signal. Place the base station on a stable and
elevated platform, such as a tripod.
