01-Systems Description
01-00 General
This chapter describes the Cobham NanoVue Receiver systems and controls. The
functioning of components is simplified where more detailed knowledge is not necessary.
01-10 Overview
Cobham’s products and services have been at the heart of sophisticated military and civil
systems for more than seventy years, keeping people safe, improving communications and
enhancing the capability of air, land and maritime platforms.
The group has four divisions employing more than twelve thousand people on five continents
with customers and partners in over 100 countries.
01-10-01 Operational Requirement
Covert monitoring is of critical importance to protect against ill eg al operat ions. These assets
can be used for detecting and catching criminals, smugglers of people, drugs, contraband or
weapons and for monitoring the ever present threat of terrorism.
There has been an increasing requirement to use the rugged transmission capabilities of
COFDM to carry general purpose Video, audio and data traffic.
01-10-02 Solution
Cobham Receivers use MPEG and COFDM technologies to provide robust and agile video RF
links that can cope with difficult environments where direct line-of-sight is not always
possible.
The Receivers feature high-quality, low latency decoding technology. All versions feature
outputs for composite video signals.
You can choose from several receiver types and several t rans mi tters to build up the perfect
solution for your operation.

01-10-03 Product Description - What is it?
The Cobham SOLO4 (and SOLO2) product range enables the user to build wireless digital
microwave video systems. Cobham SOLO4 products have been designed to provide rugged
point-to-point links for high quality full frame rate video and audio, even in non line of sight
and urban environments.
Existing analogue systems suffer from impairments such as video noise, loss of colour
information and poor image quality when line of sight cannot be maintained, and solutions
based on wireless internet standards and PC platforms deliver poor quality video.
The Cobham SOLO4 system is a digital system that uses the COFDM modulation technique,
which effectively eliminates the problems caused by multi-path and reflections.
The Cobham NanoVue Bodyworn Receiver is a fully portable digital diversity receiver.
NanoVue incorporates a high resolution daylight viewable video touch screen with a digital
diversity receiver, antennas and clip on battery pack into a robust and compact lightweight
housing. It is ideal for use as a confidence or monitoring receiver for tactical use, or for
surveillance on the move, perimeter security and fire control.
The product can be used with an external rechargeable clip on battery pack, providing
between four and five hours battery life. The unit can also run from an external DC supply.
The user has the option to record r ece i ved video to the internal SD card , for later
downloading via the Ethernet po r t. Ethernet is also used for streaming and unit
configuration.
The touch screen allows the user to switch channels and perform basic configuration without
the need for connection to a PC, making it ideal for tactical mobile situations.
The NanoVue has comprehensive On Screen Display diagnostic capability to show link
quality. Security of transmission is ensured by the use of optional AES128 / 256 bit
encryption algorithms.
01-20 The Unique Technology - How Does It Work?
The NanoVue incorporates a powerful receiver with its own display but can also be
connected to an external monitor if required. The SOLO product range has been designed to
make use of many common connectors, user interfaces and mounting patterns found on
your analogue products helping you to minimise your investment in transitioning to Cobham
digital.

The RF signal is first demodulated to prepare it for further processing. COFDM utilises
significant redundancy, producing excellent results in high multipath environments. T he data
is duplicated many times during the interleaving process. Because of the interleaving and
redundancy the information is presented in different carriers.
If one carrier is corrupted, it has little impact on video quality, as the data is repeated on
another carrier. This provides the robustness in the system.
Digital Signal Processing on the receive side is able to re co m bine all this data into a single
video stream.
The system supports wideband transmission at 6, 7 or 8MHz per channel using about 2000
carriers and narrow and ultra-narrow band transmission at 2.5, 1.25 MHz and 625 kHz using
about four hundred carriers.
01-20-03 Decryption Block
In cryptography, encryption is the process of transforming information (referred to as
plaintext) using an algorithm (called a cipher) to make it unreadable to anyone except those
possessing special knowledge, usually referred to as a key.
The result of the process is encrypted information (in cryptography, referred to as cipher
text). In many contexts, the word encryption also implicitly refers to the reverse pr ocess,
decryption (e.g. “software for encryption” can typically also perform decryption), to make
the encrypted information readable again (i.e. to make it unencrypted).
Encryption has long been used by militaries and governments to facilitate secret
communication. Encryption is now commonly used in protecting information within many
kinds of civilian systems.
Cobham offers ABS encryption as standard and AES-128 or AES-256 as licensed controlled
option.
01-20-04 Decoder B loc k
The next step is to decode the digital data stream. Cobham has chosen to use the MPEG-2
and MPEG-4 standards which are mature and well-defined.
01-20-05 Digital to Analogue Convertor Block
An analog-to-digital converter (abbreviated ADC, A/D or A to D) is a device which
converts continuous signals to discrete digital number s . The reverse operation is performed
by a digital-to-analog converter (DAC).

07-Planning
07-00 General
Radio operations always benefit from careful planning. This can help you avoid loss of signal
due to frequency clashes or other forms of interference. Issues like the provision of power to
the units can be carefully planned prior to the operation of the set.
07-10 Frequency Planning
There are not enough radio frequencies available for all radio operators to have their own
channel. You may discover that your planned radio frequency is being used by other people.
Microwave frequencies often have to be reused within the same operation by more than one
unit. The frequency management authority will try to make certain that users of the same
frequency are as far away as possible from each other, but some units (out of area units in
particular) could join at some stage in the operation.
There is one final source of frequency interference: the use of unauthorised frequencies.
This practice is illegal and has the potential to disrupt a carefully engineered frequency plan,
introduce interference to ot her fr eq uencies and cir cuits, and prevent other units from
fulfilling their mission. Radio operators should never use unauthorized frequencies.
07-20 Interference Planning
Radio frequency interference is always present in the environment. It may come from a
single source or a combination of many sources including natural or manmade frequency
interference, poor equipment condition, improper equipment usage, frequency interfer en ce,
use of unauthorized frequencies, and frequency reuse.
07-20-01 Natural Interference
Natural radio noise has two principal sources: thunderstorms (atmospheric noise) and stars
(galactic noise). It is especially noticeable at night when the lower frequencies propagate
farther than in the daytime.
The only way to reduce this type of interference is to use a directional antenna to prevent
receiving the interference from all directions. However, this will not eliminate the noise
coming from the direction of the received signal. Use of a higher frequency will also help,
although if a sky wave circuit is used, care must be exercised not to pick the highes t
frequency at which the signal will be refracted to Earth by the ionosphere (i.e., the critical
frequency).
07-20-02 Manmade Interference
Most manmade interference comes from electrical sources such as power generators, alarm
systems, power lines, auto ignition, fluorescent lighting, faulty electrical relay contact s , and
electrified railroad s . Manmade interference also includ es enemy jammers (see chapter 7).
The key to combating this form of interference is to isolate communications equipment from

DS000042 Commercial in Confidence
manmade interference. The interference from known sources such as generators can be
greatly reduced if an antenna is positioned so that an obstacle (e.g., a hill) is between it and
the source. This must be done so that the same obstacle will not block the intended radio
path. If the interference is not coming from the same direction as the intended signal, then a
directional antenna should be used.
07-30 Battery Planning
One of the biggest challenges with mobile devices has always been battery life. Many fact o r s
affect power consumption in an individual device.
Even if never taken out of the original package, disposable b atteries can lose 8 to 20 percent
of their original charge every year at a temperature of about 20-30 degrees Celsius.
This is known as the self discharge rate and is due to non-current-producing side chemical
reactions, which occur within the cell even if no load is applied to it.
High or low temperatures may reduce battery performance. Temperature has severe affects
on battery performance and these affects depend greatly on the battery chemistry used. A
rule of thumb for temperature degradation is that battery performance will decrease by 35%
at either the upper or lower range o f t he specified operating threshold, outside the threshold
the battery may not work at all.
Consider how long you expect the operation will go on and plan your battery capacity around
this.
07-40 Storage Planning
Equipment should be stored in tough, rugged and weatherproof cases with a suitable
packing material such as cubed multilayer foam.

08-Antennas
08-00 General
Of all the variables affecting single-channel radio communications, the one factor that an
operator has the most control over is the antenna. With the right antenna, an operator can
change a marginal net into a reliable net.
08-10 Antenna System
Each NanoVue Receiver unit requires two antennas. Both antennas must be fi tted to
achieve best performance.
08-10-01 Assembling the Antenna System
NanoVue Receiver units normally use simple Omni-antennas and do not require any rigging.
Naturally, it is possible to use a variety of antenna types for specialist applications. Discuss
this with your Cobham contact.
08-10-02 Attaching the Antennas
You’ll need a NanoVue receiver and two antennas. The ANT2-200250, 2dBi wide band
rugged SMA mount antenna 2.00 - 2.50GHz would be a typical example for an S-Band
receiver.
1. Connect the antennas to the SMA connectors on the top panel of the NanoVue units.
2. Do not over tighten the antenna – hand tight only!
CAUTION: Antennas should be connected directly to the NanoVue unit. If you have to use
cables between the antennas and the NanoVue (in a mobile application for example), keep
them short and use very high quality cable.
Note: There are many types of antenna that can be fitted to the NanoVue Receiver unit.
Your antennas may look different from those in this guide. For more advice on antenna types
call your Cobham representative.
08-20 Downconverter System
All our receiver units use downconverters to lower the frequency from microwave (L, S
and C-Band) to an Intermediate Frequency (IF) between 51 and 858MHz that the onboard
tuners in the receivers can us e .
The NanoVue has the downconverters built into the unit. This means you must choose the
band you want to operate in when you order your NanoVue and you will be given the correct
variant.

away from the NanoVue (say, in an aircraft or vehicle) then keep the cable run short. Always
use the best possible RF cable to avoid losses.
08-50 Antenna Polarization System
COFDM links are very robust and are tolerant to changes in antenna position, however, it is
advantageous to try and keep the antennas in the same plane if possible.

For increased portability, the unit can be powered by the custom NanoVue clip-on
rechargeable battery pack, which provides between 4 and 5 hours continuous battery life.
09-30 Power Consumption
Here are the figures for power loading on the NanoVue Receiver.
DC Input 6 to 16V Reverse Polarity Protected.
Power Consumption is typically 9W depending on mode.
As an example, current at 12V and 9W is 0.75A.
09-30-01 Battery Calculations
You’ll need to know how long the unit will operate with batteries. Here’s how you work it
out.
An approximate measurement of a battery’s ability to provide energy is its rating in amp
hours (Ah). A 100Ah battery will produce 100 amps for 1 hour.
A 100Ah battery could produce 1 amp for 100 hours or 50 amps for 2 hours, 4 amps for 25
hours or 25 amps for 4 hours etc.
The formula you need is:
Time (H) = Battery capacity (Ah) / Current drawn (I)
Where:
H is the time the battery will last.
Ah is the amp hours of the battery you’re planning to use
I is the current drawn by the unit you want to power
Let’s take a NanoVue Receiver as an example. If we look at the Power section of the
Data Sheet, we see these numbers:
Power
DC Input 6 to 16V Reverse Polarity Pro tected
Power Consumption
9W depending on mode
So, we have a range of voltages, no current shown, but they do tell us typical power
consumptions in Watts!
First thing to do is choose a voltage. This is normally is 12VDC when we are working off
the batteries we normally supply.
Now, we work out the current drawn by the unit at 12VDC.
The formula you need is:

Current drawn (I) = Power (W) / Voltage of Battery (V)
Where:
I is the current drawn by the unit in amps
W is the power used by the unit in watts
V is the voltage used by the unit in volts
Let’s select a power consumption of 10 W (the worst case) and run the current calculation.
I=W/V, so I=9/12 = 0.75 amps
Let’s use a 12V, 4.2Ah battery with our transmitter. Now, we can run the time calculation.
H=Ah/I, so t=4.2/0.75 = 5.6 hrs.
09-40 Back Up Battery System
There are no backup batteries in this unit.
09-50 Overload Protection System
It is important to protect all el e ctrical devices from overlo a d conditions or reverse voltag es.
There are a number of devices that do this task for us.
¢ Fuses
¢ Circuit Breakers
¢ Sacrificial Components
09-51 Fuse System
In electronics and electri cal engineering a fuse is a type of s a cr ificial over current protection
device. Its essential component is a metal wire or strip that melts when too much current
flows, which interrupts the circuit in which it is connected. Shor t circuit, overload or device
failure is often the reason for excessive current.
There are no fuses inside the unit.
09-52 Circuit Breaker System
A circuit breaker is an automatically-operated electrical s witch designed to protect an
electrical circuit from damage caused by overload or short circuit. Its basic function is to
detect a fault condition and, by interrupting continuity, to immediately discontinue electrical
flow.
Unlike a fuse, which operates once and then has to be replaced, a circuit breaker can be
reset (either manually or automatically) to resume normal operation.
There are no Circuit Breakers inside the unit.

11-31 Global Positioning System
Global positioning system (GPS) is a system that radio operators may be required to operate.
Global positioning system is a space-based navigation system designed to provide 24-hour
continuous worldwide, all-weather precise position, and time measurement.
The GPS consists of a space segment (satellite), control segment (monitors stations on
Earth), and user segment (GPS receivers).
The system operates by satellites sending out two signals on non-changing frequencies. The
GPS receiver receives the s ignals transmitted by the sat e l l ites and computes the user’s
position.
GPS (by being an all-weather, jam-resistant, continuous system) gives users highly accurate
navigation; worldwide, three-dimensional position or location velocity; and time infor mation.
As a passive, receive-only system, GPS can be employed at the individual level in such
nondescript terrain as jungles, mountain ranges, or deserts.
11-40 Internet Protocol (IP) Payload System
The NanoVue has an Ethernet connection which is used to configur e t he unit from your PC
using your browser software and the units control pages. This connection can also be use to

that are manually managed
(or do not feature a DHCP
server), users may prefer to
assign an IP address
manually.
IP Address
Example:
192.168.2.120
If the NanoVue is not
automatically acquiring its
IP address via a DHCP
server then a fixed IP
address needs to be
assigned to the unit
Enter an IP address for
this NanoVue in the IP
address text box. It can be
any class of network you

13-Encryption
13-00 General
The target is focused on intercepting your radio signal. T o do this, all that they need is a
radio receiver that operates in the same mode and on the same frequency you are using to
transmit. The mere fact that you are operating gives them valuable information. It tells them
that you are in the area and by the number of stations operating on the same frequency
they can estimate the size of the operation against them. If your radio net is operating in the
clear, the target specialists can see or hear exactly what is being transmitted for even more
information. When analysing the traffic patterns, the target can work out which station is the
net control station and identify the headquarters.
13-10 Encryption System
If the AES scrambling option has been purchased for the SOLO system in use, then it is
possible to encrypt the link. Both AES128 and AES256 are licence-controlled feat u r es. You’ll
need to encrypt the traffic leaving the transmitter and set up th e r ece i ver for decrypt.
Note: The word Encryption applies to the whole process of encryption and decryption.
We’ll just use the word encryption for this receiver manual even though what is actually
going on here is a decryption proce s s.

Means…
AC
Alternating Current. Current that is continually changing in
magnitude and periodically in direction from a zero reference
level.
AES
In cryptography, the Advanced Encryption Standard (AES)
is an encryption standard adopted by the U.S. government. The
standard comprises three block ciphers, AES-128, AES-192 and
AES-256, adopted from a larger collection originally published as
Rijndael. Each AES cipher has a 128-bit block size, with key
sizes of 128, 192 and 256 bits, respectively.
Amplification The process of increasing th e s trength (current, voltage or
power) of a signal.
Amplitude The level of an audio or other signal in voltage or current. The
magnitude of variation in a changing quantity from its zero
value.
Amplitude
Modulation
Modulation in which the amplitude of the carrier wave is varied
above and below its normal value in accordance with the
intelligence of the signal being transmitted. Also called AM.
Analogue
Analog transmission is a transmission method of conveying
voice, data, image, signal or video information using a
continuous signal which varies in amplitude, phase, or some
other property in proportion to that of a variable.
Antenna An
antenna
(or
aerial
) is a transducer designed to radiate or
receiver electromagnet i c ene r gy (generally RF).
Antenna Bandwidth The frequency range over which a given antenna will accept
signals.
Antenna Gain The effectiveness of a directional antenna as compared to a
standard non-directional antenna. It is usually expressed as the
ratio in decibels of standard antenna input power to directional
antenna input power that will produce the same field strength in
the desired direction. For a receiving antenna, the ratio of signal

power values produced at the r eceiver input terminals is used.
The more directional an antenna is, the higher is its gain.
Attenuation Power loss resulting fr om conductor resistance and dielectric
loss within the insulating material used to separate the
conductors.
ASI
Asynchronous Serial Interface. A streaming data interface
which often carries an MPEG Transport Stream.
An ASI signal can carry one or multiple SD, HD or audio
programs that are already compressed, not like an
uncompressed SD-SDI (270Mbs) or HD-SDI (1.45Gbs). An ASI
signal can carry varying amounts of data but is always padded
to run at a fixed line rate of 270 Mb/s.
B
Means…
BNC
Bayonet Neill-Concelman – A very common type of RF
connector used for terminating coaxial cable.
Bandwidth
The width of a band of frequencies used for a particular
purpose.
C
Means…
COFDM Coded Orthogonal Frequency Division Multiplexing is a
frequency-division multiplexing (FDM) scheme utilized as a
digital multi-carrier modulation method. A large number of
closely-spaced orthogonal sub-carriers are used to carry data.
D
Means…
Digital
A digital signal is a discontinuous signal that changes from
one state to another in discrete s teps.

Electromagnetic fiel d
The field of force that an electrical current produces around the
conductor through which it flows.
Electromagnetic
Waves
A wave propagating as a periodic disturbance of the electric and
magnetic fields and having frequency in the electromagnetic
spectrum; the means by which energy is transmitted from one
place to another.
F
Means…
FEC
Forward Error Correction is a system of error control for data
transmission, whereby the sender adds redundant data to its
messages, also known as an error-correction code. This
allows the receiver to detect and correct errors (within som e
bound) without the need to ask the sender for additional data.
The advantage of forward error correction is that a backchannel is not required, or that retransmission of data can often
be avoided, at the cost of higher bandwidth requirements on
average. FEC is therefore applied in situations where
retransmissions are relatively costly or impossible.
FOV
Field of View - The field of view (also field of vision) is the
angular extent of the observable world that is seen at any given
moment.
fading A perio dic decrease in received signal strength
Frequency The rate at which a process repeats itself. In radio
communications, frequency is expressed in cycles per seco nd.
Signals also have a property call ed wavelength, which is
inversely proportional to the frequency.
Frequency
Modulation
The process of varying the frequency of a carrier wave, usually
with an audio frequency, in order to convey intelligence. Also
called FM.
G
Means…
GHz
Gigahertz - One gigahertz is equal to 1,000 megahertz (MHz)
or 1,000,000,000 Hz.
Gain
The increase in signal strength that is produced by an amplifier.

the less obtrusive the background noise is.
Signal In electronics, a signal is an electric current or electromagnetic
field used to convey data from one place to another. The
simplest form of signal is a direct current (DC) that is switched
