2APS-U Overview
The APS-U provides multi-frequency RTK GNSS capability together with GNSS Heading, L-Band positioning from TERRASTAR, and
wireless communications within a rugged MIL-STD-81 0 housing for the broadest range of applications.
For maximum flexibility, the design is scalable from a single antenna GNSS receiver to full options with Heading, wireless links and L-
Band capability.
The rear panel has an extensive suite of interfaces for data output, timing, event marks, and a second antenna port for GNSS
Heading. Integrated wireless options optional GSM cellular modem and UHF radio modem for transmission or reception of RTK
corrections.

2.4 Internal Memory
The APS-U has 2GB Memory for internal data logging. When using with APS-U for internal data logging, data is logged in SBF or
NMEA format, and may be retrieved after the logging session is complete. Files can be accessed via the logging tab using the
APS-U web interface.

15 | P a g e
3Web Interface
The APS-U has an on-board web interface, which is accessible from the Ethernet connection. All routine settings are made from the
APS-U web interface for ease of use.
By default, the APS-U has a DHCP address http://aps-u-snxxxxx, where xxxxx are the five digits of the APS-U serial number, (to be
found on the top right of the rear panel of the APS-U enclosure)

4Receiver Administration
4.1 Change IP Settings
The default DHCP address can be changed into the desired static address selecting the tab “Ethernet”.
To apply the changes press “OK”

17 | P a g e
4.2 Configuration management
The receiver configuration includes all the user-selectable parameters, such as the elevation mask, the PVT mode, UHF, COM port
settings etc.
-The default configuration (RxDefault) contains factory settings which can be always retrieved.
-The Current configuration contains the current receiver configuration.
-The Boot file contains the configuration that is loaded at boot time.
-User-defined configuration files (User1, User2) can be used to store frequently-used user-specific configurations inside the
receiver.
The current receiver configuration can be saved and archived for future reuse or loaded on a different receiver. Once the
configuration is saved, it can be recalled.
Any change to the default settings will be implemented in the current configuration of the APS-U and are not automatically copied in
the boot configuration of the unit.
When changing the APS-U configuration from its factory settings, a pop-up at the bottom right corner of the screen will appear. To
make the changing effective after booting press OK.
Changes applied can be visualized expanding the configuration. To download the configuration in a text file, click the green arrow.
To upload a configuration script, select the light blue arrow and browse the desired file.

4.3 Upgrading the firmware or uploading a new permission file
The APS-U firmware can be upgraded via the “Upgrade” screen in the “Admin” menu. You can upgrade the unit by selecting a
.SUF-file with a more of the firmware version.
This procedure can also be used to upload a new permissions file to enable additional features on the unit.
4.4 Reset the receiver to default settings
The receiver can be reset to the default settings via the “Reset” screen in the “Admin” menu. To reset the unit to factory
configuration, mark the “config” checkbox before clicking “OK”.

19 | P a g e
4.5 User Administration
The User Administration screen in the Admin menu offers the possibility to configure access levels for different users. Users can be
configured as “viewer” (view status and settings, but not change them) or “user” (full access).

20 | P a g e
5Basic Configurations
5.1 How to set the APS-U in RTK rover mode using the UHF radio
Step 1: Enable RTK Rover PVT mode
If when starting from the default configuration, RTK rover is enabled by default.
Step 2: Activate UHF radio.
When starting from the default configuration, in the status window, UHF can be activated in the UHF widget. If the unit was
preconfigured before, UHF will now be activated and the unit will start receiving corrections.
Remark: If Ntrip was previously enabled, the user will be presented with the choice to use either UHF or Ntrip.
