 Service & support

With 125 W of output power packed into a rugged and

small unit the NGT™ MR Transceiver is suited to mobile

and base confi gurations. The NGT™ MR is more affordable

than manpack based solutions while delivering the same

critical HF needs such as reliable, secure and interoperable

communications.

RUGGED DESIGN

The NGT™ MR is built to survive the world’s harshest environments.

The product meets MIL-STD-810F for shock, vibration and dust

ingress. Electrical protection is provided against reverse polarity,

over-voltage, under-voltage, antenna VSWR mismatch and over-

temperature.

INNOVATIVE USER INTERFACE

Codan’s cleverly designed NGT™ MR Handset and intuitive interface

provides many benefi ts over traditional removable front panel

designs. Its small size and light weight make it simple to install in

many locations, especially in vehicles where space is limited. The

menu system includes a call address list and the keypad is arranged

like a mobile phone to ensure that radio operation is simple, familiar

and intuitive. With convenient access to the programming port,

located on the base of the Handset, users will fi nd it quick and easy to

program the RF unit.

FREQUENCY HOPPING (ECCM)

The CODAN™ NGT™ MR provides

128-bit security strength frequency

hopping. It operates during

scanning, and during reception

and transmission of ALE calls to

enable silent operation. Users can

optimise performance via three

user-switchable hopping rates of

6 / 12 / 25 hops per second.

An additional level of security

can be achieved through the

use of a 10 digit user PIN.

AUTOMATIC LINK ESTABLISHMENT

The NGT™ MR is fully compliant with

both FED-STD-1045 and JITC certifi ed

MIL-STD-188-141B ALE waveforms.

Codan’s implementation of ALE

incorporates unique capabilities such

as maintenance of channel quality

information (LQA) on a 24-hour basis.

This enables the Transceiver to select

a suitable channel at any time of

the day, from the moment it is

switched on. This results in faster

channel selection than conventional

ALE system with signifi cantly less

sounding activity required.

The Listen-Before-Transmit capability

detects voice and data traffi c on the

channel before initiating ALE. This

prevents calling on channels that

already have traffi c.

The NGT™ MR provides an extensive

range of ALE and Selcall based call

facilities, including Phone calls, GPS

polling and sending, Emergency calls,

and Remote Diagnostics.

The multiple network scanning

capability enables multiple networks

to be scanned simultaneously. An

ability to simultaneously decode

voice, Selcall and ALE calls on the

same channel enables maximum

interoperability in mixed vendor

network environments.

SMART MONITORING AND SCANNING

When an operator is absent, the

NGT™ MR™ generates an automatic

log containing the caller’s identity,

time and channel number that

can be displayed upon their return.

With multiple net adaptive scanning,

the NGT™ MR™ automatically adjusts

scan times for multiple networks

according to the channels’ preset

scan times. This feature gives the

most effi cient scanning time possible

for Selcall, ALE and voice detection.

The NGT™ MR™ features fl exible

scanning networks, with up to

20 scan tables containing up to

100 channels. Scan rates of up to

8 channels per second are possible,

which provides increased capacity

for HF networks based on the MR™.

With the syllabic Voice Mute, the

NGT™ MR™ effectively detects

voice patterns even in high-noise

environments. This ensures mute

is only opened after it detects

speech on any scanned or

monitored channels.

When Selcall or ALE selective calling

is implemented, users are able to

scan multiple channels or networks.

The operator is only alerted when a

call addressed to them specifi cally is

received. This relieves the operator

from continuous manual monitoring

for relevant incoming traffi c.

VOICE ENCRYPTION

The NGT™ MR™ has a choice of three

internally fi tted voice encryption

options to suit all levels

of communications security.

The CIVS voice encryption option is a

cost effective software enabled voice

scrambler capability that is simple to

use and provides a basic level of voice

security.

The CES voice encryption option

provides high level 128 bit voice

security. Up to 97 16-digit user

programmable keys are provided.

An additional layer of security is

provided through the ability to

assign a PIN number during a secure

communications session.

The AES voice encryption option

provides 256-bit security according

to the Advanced Encryption Standard,

with up to 256 user programmable

encryption keys.

Optimal voice clarity is provided

through the use of a Mixed-

Excitation Linear Predictive enhanced

(MELPe) Vocoder. The MELPe Vocoder

supports 1200 bps and 2400 bps user

selectable data rates.

All voice encryption options for the

NGT™ MR™ are fully integrated with

core Transceiver functions like Selcall

and ALE scanning to ensure simplicity

of operation.

GPS SUPPORT

The NGT™ MR™ supports connection of GPS via NMEA0183 compatible

GPS receivers. This enables polling and sending of GPS positions over air.

Distance and bearing to other users can be displayed. When used with

Internav™ CHF tracking PC software, up to 100 vehicles can be tracked.

Internav™ provides advanced features such as corridor and alarm zones,

waypoints, and recording of emergency events.

DATA COMMUNICATIONS

The NGT™ MR™ supports the CODAN™ high speed RM50e HF Data

Modem. This provides MIL-STD-188-110A/B data waveforms up to

9600 bps, or 19200 bps with the ISB option. Codan’s RC50-C Email

software works with the NGT™ MR™ and RM50e Modem, to provide

email capability over conventional SMTP / POP mail clients such as

MS Outlook. Features include compression and Data Rate Control (DRC),

ensuring transmission speed is optimised to the channel conditions.

SERVICE AND SUPPORT

Codan’s commitment to its customers goes beyond producing

world-class communications equipment. With customers in more than

150 countries Codan has developed a highly responsive global service

and support capability to ensure prompt and accurate support services.

These support services include installation and commissioning of

equipment, on-site and factory based training, and the provision of

spare parts worldwide.

Codan provides training on the installation and use of equipment with

in-country courses. Customers may also attend courses at Codan’s

purpose-built training suite at its Adelaide headquarters in Australia,

or at any of the Company’s international offi ces.
