General information
Satellite TV reception, general information, footprints
Satellite orbits
All TV-satellites move in so called geostationary orbit 36.000 km above the
Earth's equator. At this specific altitude their angular velocity matches the
Earth's exactly and make them appear motionless in the sky.
When viewed from the northern hemisphere the satellites appear along an arch
with the satellite due south at the top.
The necessary separation between satellites depends on the frequency and the
size of the antennas and is usually 3°. A large number of satellites can be colocated in the same position as long as
they transmit on different frequencies.
Co-located satellites are allowed to
deviate 0,1 degrees within their position,
which equals to a cube with a side of 73
km. At position 19.2 deg East (Astra 1) for
instance, there are actually 5 satellites
within the same position.
The satellites get their signals from an
uplink station. The satellite that
receives the signal shifts the
frequency down to about 1012 GHz, amplifies it and
transmits it back towards
earth by what is called
transponders. The satellites
electrical power comes from solar
panels, and the satellite is kept in
position by small jet-motors mastered
by ground-control. The actual life-span
of a satellite mainly depends on fuel
left for positioning jets.

Chapter 1: General information
Antenna and LNB
Transponders
TV-satellites that can be viewed with Satellite antennas transmit in the Ku frequency
band on frequencies between 10.700 and 12.750 MHz. Each satellite typically has
several transmitters or transponders that carry a number of digital TV and/or radio
channels.
Antenna and LNB
When the signals reach the antenna they are focused by the dish and radiated into
the feedhorn and passed along to the LNB (Low Noise Block converter). The LNB
amplifies the signals and transforms them to a lower frequency within the so-called
satellite IF-band. Satellite receivers use the IF band which covers 950-2150 MHz
(2300 MHz in some areas).
Since the Ku-band covers 2050 MHz and the IF-band only 1200 MHz, it is necessary
to divide the incoming signals into a high band and a low band with separate outputs
on the LNB. Low-band IF-signals are shifted 9750 MHz down and high-band IFsignals 10600 MHz down.
3
Polarisation
In order to increase the number of channels in each satellite slot the signals are
transmitted with different polarisation. Two kinds of polarisation are used in TV
transmissions: linear and circular.
Linearly polarised signals propagate with their wavefronts aligned either horizontally
or vertically. The receiving LNB can then separate the two polarisations if it is aligned
properly.
Circularly polarised signals propagate with their wavefronts rotating either clockwise
or counter-clockwise
The main advantage with linear polarisation over circular is that the isolation between
the two modes is better. The main advantage with circular polarisation is that the
feedhorn doesn't need to be aligned.

Footprints
The satellite footprint is a map showing a satellite’s fieldstrength or EIRP
(Effective Isotopic Radiated Power). It's not a real unit, but more a practical
model you can use when you graphically view the radiated area.
Every satellite has it's own footprint, and by consulting the footprints and the
conversion table you can estimate the antenna size needed.
One satellite can transmit several beams, where every beam has it's own
footprint and content regarding channels and service providers.
For updated information regarding footprints, frequencies, service providers etc.
we recommend you to consult websites such as www.lyngsat.com,
www.satbeam.com or www.kingofsat.net.
Below you can see a few typical footprints Anik F1R (W107,3), Astra 1H (E28,2)
and NSS6 (E95,0)

Functional description
Description of operation
After power-up, the antenna performs a self-test and calibration lasting up to five
minutes. It then enters search mode and starts searching for a satellite. The antenna
automatically calculates the elevation of the selected satellite using a built-in GPSreceiver to determine the current position1.
After locking on a satellite, the ID-receiver attempts to identify it and repositions the
antenna if necessary. Polarisation is adjusted automatically when a satellite is
identified.
For a more detailed explanation a satellite identification see sections satellite ID and
satellite ID menu
Calibration
Polarotor turns to counter clockwise mechanical end stop (seen from behind)
Elevation goes down to mechanical end stop
Azimuth turns to counter clockwise mechanical end stop
Elevation goes up then down (test of elevation gyro)
Azimuth goes clockwise-counter clockwise (test of azimuth gyro)
Elevation goes up to 90 degrees (test of inclinometer)
Antenna makes a 45 degree clockwise sweep
Antenna makes a counter clockwise noise sample sweep
After this it goes into search mode, trying to locate a satellite
Satellite search
Two search patterns are used. The large pattern is used when no information is known
about the satellite positions. The antenna then moves in full circles at different
elevation angles. The small pattern is used to reacquire a satellite after loss of
tracking.
If the default tracking mode (Auto) is set in the SatID-menu then the search is made
with a signal detector that receives signals from a selectable part of the satellite IFband.

If the antenna has been switched off for a long time, the GPS-receiver may take
up to 20 minutes to initiate. It may then be necessary to enter the ship's position
manually in the service menu.
7
In some circumstances it can be useful to carry out the
search using the tuner - the Tuner Tracking Mode.
The antenna will then only lock on a satellite
transmitting a DVB-S signal on the preset frequency
with a certain symbol rate and FEC. These settings are
available from the PC-program only.
Tracking
When the signal level exceeds the threshold level during a search, tracking is
initiated. The antenna then uses a combination of gyroscopes and dish scan to keep
it pointed at the satellite.
The dish scan continuously rotates the antenna in a small angle around its aiming
point to correct for gyroscope drift. The signal is monitored either with a tuner set to
a specific frequency or with a signal detector via a bandpass filter. See section
Tracking mode
Signals from two of the four LNB outputs are tapped off and one fed to the tuner and
the other to the detector. Vertical low is the default LNB output for the detector and
horizontal high for the SatID.
Satellite identification
After locking on a satellite the ID-receiver attempts to identify it by matching the
transponder's network identifier code or NID with the antenna's internal list.
If the identified satellite is another one than selected, the correct position is
calculated and the antenna automatically repositioned. When a correct match is
made, "Confirmed" is written after the satellite name in the display.
Please see section Network IDs.
If the satellite remains unidentified, the antenna tries to acquire another
satellite.
Chapter 2: Functional description

Satellite identification
After identification polarisation is adjusted to match the satellite.
The angles are calculated based on the ship's position and the satellite's longitude
assuming a 0° angle in locations on the same longitude. Compensation for
ship´s movements is also performed continuously.
As some satellite’s polarisation is offset, a provision is made to fine-tune it in the SatID
menu of the PC-program.
9
Polarisation control
During initial NID-scanning, polarisation is set to 0°. If no identification is made, scans
are executed on -15° and 15° as well.
If the satellite remains unidentified, the antenna tries to acquire another satellite.

Antenna location
Choose a location that has an unhindered view of the satellite at the point of lowest
elevation. Ideally, a location should be chosen as close to the vessel's centre as
possible while keeping cable lengths to a minimum.
If the antenna is placed on a pedestal, care must be taken that it does not flex
or vibrate.
The satellite TV antenna's LNB is equipped with a radar filter but to avoid damage
to the LNB it is strongly advised that it should not be placed in the path of a radar beam.
It must not be placed in the path of a VSAT antenna.

Installation
Radar
It is difficult to give exact guidelines for the minimum distance between a radar and
the antenna because radar power, radiation pattern, frequency and pulse length/
shape vary from radar to radar. Further, the antenna is typically placed in the near
field of the radar antenna and reflections from masts, decks and other items in the
vicinity of the radar are different from ship to ship.
However, it is possible to give a few guidelines:
Since a radar radiates a fan beam with horizontal beam width of a few degrees and
vertical beam width of up to +/- 15o, the worst interference can be avoid by mounting
the satellite TV antenna at a different level - meaning that the antenna is installed
minimum 20o above or below the radar antenna. Due to near field effects the benefit
of this vertical separation could be reduced at short distance (below approx. 10 m)
between radar antenna and satellite TV antenna. Therefore it is recommended to
ensure as much vertical separation as possible when the satellite TV antenna has
to be placed close to a radar antenna.

The satellite TV antenna must be mounted as far away as possible from ship’s
radar and high power radio transmitters (including Inmarsat based systems),
because they may compromise the antenna performance. RF emission from radars
might actually damage the satellite TV antenna.

Mounting
Rigid mounting is essential for proper function and parts of the vessel subject to heavy
resonant vibrations are unsuitable for satellite TV antenna installation.
If pedestals higher than 1 m are used utmost care must be taken to ensure rigidity and
that the natural frequency of the pedestal/satellite TV antenna is as high as possible.
Mounting bolts should be tightened with a torque of 20 Nm, and medium or permanent
strength thread-locking fluid applied.
The minimum acceptable seperation (d min.) between a radar and the satellite TV
antenna is determined by the radar wavelength/frequency and the power emitted by
the radar. The tables below show some “rule of thumb” minimum separation
distances as a function of radar power at X and S band. If the d min. separation listed
below is applied, antenna damage is normaly avoided. “d min.” is defined as the
shortest distance between the radar antenna (in any position) and the surface of the
satellite TV antenna.
