The PNG system consists of one base station and one or more handheld rechargeable
radios, chargers for the handhelds, as well as an optional control panel connected to the
base station. The PNG Base Station and Control Panel are installed in the aircraft and
supplied with power from the aircraft system.
The PNG handhelds implement functionality to suppress surrounding noise, and to secure
optimal voice activation performance. They implement functionality to connect to the PNG
Base Station in the helicopter (intercom mode), as well as functionality to communicate
directly with other PNG handhelds, or handheld to other radios (direct mode).
The handheld radios are designed to be mechanically robust and the MP50 handheld radio is
waterproof down to a depth of 3 meters to withstand extreme operating scenarios typically
experienced in a SAR and multirole-configured aircraft.
Through the handheld internal microphone, the system enables communication with the
survivor/ground rescue party without helmet removal.
Depending on the configuration and part number, the handhelds are equipped with a GPS
receiver. The position of the handheld device may be polled by the PNG Base Station, and
presented on the PNG Control Panel in the aircraft.
The PNG Base Station is typically connected to the aircraft ICS, and may support multiple
connection points for audio. It is capable of delivering a PTT signal to other systems, as well
as triggering transmission based on a received PTT signal or VOX activation.
1.3 Radio
The PNG system operates a wireless link between the PNG Base Station and the handheld
radios in the UHF band. Exact frequency configuration is done at production, based on
customer input to available frequencies and bandwidth in the region they are to be operated
in. The PNG system will normally be configured within a 10 MHz band in the frequency range
397 to 470 MHz. The PNG Base Station will support the full 397 to 470 MHz range
(depending on the antenna installation in the aircraft), while the handhelds support 10 MHz
bands through the 397 to 470 MHz band, depending on the installed antenna. Antennas are
available through the band.
The wireless link is a single frequency, duplex, interception free, digital radio link.
The handheld radios will operate at an output power of up to 400mW using a licence specific
frequency allocation.
The PNG system will not set any limit to the number of simultaneous receivers, but the
number of simultaneous transmitters is limited by the available bandwidth and allocated
timeslots. The PNG system allows three simultaneous transmitting handhelds.
The handheld radios support Maritime VHF mode, and channels can be configured in the
156-162MHz band.

Section 2: Operation
The PNG system consists of one PNG Base Station and one or more handheld radios. To
make all units in the PNG system interoperable, each unit must be configured with
compatible parameters. Configuration of the PNG system will imply setting of radio
frequencies, defining groups and setting scrambling or encryption parameters.
Multiple configurations may be stored on a device to support different operational modes.
The PNG system can be preconfigured from the vendor, or the configuration may be set by
the operator’s avionics department.
Ahead of flight all units in the PNG system will be set to compatible configuration. Different
types of operation may use different configurations, due to radio frequencies, group
definitions or other parameters. During operation and in flight the configuration on the PNG
Base Station is normally not changed, but may be required in some special conditions. Such
conditions may be caused by radio interference, where alternative frequencies may be
required, and an alternative configuration is selected.
The operational scenario may also require different handheld configurations to be loaded in
different phases of the operation, e.g. to change group subscriptions during the mission.
Switching between the handheld configurations is done by the handheld operator by a simple
button push.
The installation of the PNG system in an aircraft is dependent on the aircraft type and use
scenarios. The PNG Base Station may be installed in a static configuration with circuit
breaker and a switch for power, and optionally switches for mute and broadcast. The system
is in this configuration locked into one configuration for the Base Station.
Alternatively, and recommended, a PNG Control Panel may be installed. The PNG Control
Panel supports rotary buttons and discreet buttons, for controlling active configuration, mute
and broadcast, as well as power on/off. There is also a display that gives status information.
Actual placement and operation of switches or PNG Control Panel is dependent on the
aircraft type and installation.
2.1 Groups
The PNG Base Station supports organising the communication on the wireless link into
groups. Groups are a set of audio channels on the wireless link, and a set of physical audio
interfaces on the base station. The PNG system will support 2 groups depending on the
available radio resources (channel bandwidth).
The PNG Base Station will by default have audio to and from the first group on physical
audio interface 0 and the second group on physical interface 1.
The handhelds are configured to listen (receive) to one or more groups (allowing
simultaneous listening to multiple groups). Transmit is configured to one primary group

through PTT/VOX, but it is possible to configure transmit to a secondary group through
configuration and use of the secondary PTT on the handheld.
When the PNG system is set up, one or more configurations are defined, see section 2.2
Configurations.
2.2 Configurations
Both the handhelds and the PNG Base Station use configurations to control the behaviour of
the devices. They can hold a number of configurations, with different operational parameters.
A configuration contains a minimum of the following parameters:
•Logical name of the configuration
•Radio parameters (frequency, modulation, and channel bandwidth)
•Group subscriptions for receive
•Group subscriptions for transmit
•Configuration of remote PTT control (handheld activation of PTT from the PNG Base
Station to the intercom)
The different pre-programmed configurations can be selected at start or during mission from
the PNG Control Panel. Typically, there will be several configurations when different radio
channels shall be made available. There can also be different configurations for different
mission types as e.g. SAR and EMS missions.
The different configurations are selected on the PNG Control Panel with a rotary push button,
and identified by the logical name. When selected, all relevant parameters are loaded.
On the handheld, the configuration is selected with the up/down arrows, and identified with a
short two letter name and a long logical name (scrolling display).
Pre-programmed configurations can either be pre-ordered from the equipment vendor, or
changed by a qualified equipment operator with a PC based programming tool.
2.2.1 Encryption
With the PNG system all user data are encrypted according to the AES-256 encryption
standard before they are transmitted over the air. When delivered from factory, the PNG
Base Station uses a default encryption key called “AXNES DEFAULT”. Changing this
encryption key requires the user to acquire an encryption key programming kit. Note that the
PNG Base Station and all handhelds in a system must use the same encryption key in order
to connect and communicate with each other.

2.3 General UI
The PNG Base Station itself has no visible UI. All control and status of the behaviour is
reflected in the PNG Control Panel.
The UI consist of a 3 lines by 16 characters LED matrix display, two rotary push buttons, a
power on/off button, two buttons for activating / deactivating mute and broadcast, and one
button for activating menu mode.
2.4 Power on/off
The PNG Base Station and Control Panel will by default automatically turn on when power is
applied. The system will conduct an initial in-built test, check communication link with base
station and report status on the control panel, refer to section 2.11 Error conditions.
After power-up, the system loads the last used configuration and is ready for use.
