Satellite TV reception, general information, footprints

Satellite orbitsAll TV-satellites move in so called geostationary orbit 36.000 km above theEarth's equator. At this specific altitude their angular velocity matches theEarth's exactly and make them appear motionless in the sky.When viewed from the northern hemisphere the satellites appear along an archwith the satellite due south at the top.The necessary separation between satellites depends on the frequency and thesize of the antennas and is usually 3°. A large number of satellites can be co-located in the same position as long asthey transmit on different frequencies.Co-located satellites are allowed todeviate 0,1 degrees within their position,which equals to a cube with a side of 73km. At position 19.2 deg East (Astra 1) forinstance, there are actually 5 satelliteswithin the same position.The satellites get their signals from anuplink station. The satellite thatreceives the signal shifts thefrequency down to about 10-12 GHz, amplifies it andtransmits it back towardsearth by what is calledtransponders. The satelliteselectrical power comes from solarpanels, and the satellite is kept inposition by small jet-motors masteredby ground-control. The actual life-spanof a satellite mainly depends on fuelleft for positioning jets.

Chapter 1: General information

Antenna and LNB

TranspondersTV-satellites that can be viewed with Satellite antennas transmit in the Ku frequencyband on frequencies between 10.700 and 12.750 MHz. Each satellite typically hasseveral transmitters or transponders that carry a number of digital TV and/or radiochannels.

Antenna and LNBWhen the signals reach the antenna they are focused by the dish and radiated intothe feedhorn and passed along to the LNB (Low Noise Block converter). The LNBamplifies the signals and transforms them to a lower frequency within the so-calledsatellite 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 necessaryto divide the incoming signals into a high band and a low band with separate outputson the LNB. Low-band IF-signals are shifted 9750 MHz down and high-band IF-signals 10600 MHz down.

3

PolarisationIn order to increase the number of channels in each satellite slot the signals aretransmitted with different polarisation. Two kinds of polarisation are used in TVtransmissions: linear and circular.

Linearly polarised signals propagate with their wavefronts aligned either horizontallyor vertically. The receiving LNB can then separate the two polarisations if it is alignedproperly.

Circularly polarised signals propagate with their wavefronts rotating either clockwiseor counter-clockwise

The main advantage with linear polarisation over circular is that the isolation betweenthe two modes is better. The main advantage with circular polarisation is that thefeedhorn doesn't need to be aligned.

FootprintsThe 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 practicalmodel you can use when you graphically view the radiated area.Every satellite has it's own footprint, and by consulting the footprints and theconversion table you can estimate the antenna size needed.One satellite can transmit several beams, where every beam has it's ownfootprint 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.

Functional descriptionDescription of operation

After power-up, the antenna performs a self-test and calibration lasting up to fiveminutes. It then enters search mode and starts searching for a satellite. The antennaautomatically calculates the elevation of the selected satellite using a built-in GPS-receiver to determine the current position1.After locking on a satellite, the ID-receiver attempts to identify it and repositions theantenna if necessary. Polarisation is adjusted automatically when a satellite isidentified.For a more detailed explanation a satellite identification see sections satellite ID andsatellite ID menu

CalibrationPolarotor turns to counter clockwise mechanical end stop (seen from behind)Elevation goes down to mechanical end stopAzimuth turns to counter clockwise mechanical end stopElevation 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 sweepAntenna makes a counter clockwise noise sample sweep

After this it goes into search mode, trying to locate a satellite

Satellite searchTwo search patterns are used. The large pattern is used when no information is knownabout the satellite positions. The antenna then moves in full circles at differentelevation angles. The small pattern is used to reacquire a satellite after loss oftracking.If the default tracking mode (Auto) is set in the SatID-menu then the search is madewith a signal detector that receives signals from a selectable part of the satellite IF-band.

1 If the antenna has been switched off for a long time, the GPS-receiver may takeup to 20 minutes to initiate. It may then be necessary to enter the ship's positionmanually in the service menu.

In some circumstances it can be useful to carry out thesearch using the tuner - the Tuner Tracking Mode.The antenna will then only lock on a satellitetransmitting a DVB-S signal on the preset frequencywith a certain symbol rate and FEC. These settings areavailable from the PC-program only.

TrackingWhen the signal level exceeds the threshold level during a search, tracking isinitiated. The antenna then uses a combination of gyroscopes and dish scan to keepit pointed at the satellite.

The dish scan continuously rotates the antenna in a small angle around its aimingpoint to correct for gyroscope drift. The signal is monitored either with a tuner set toa specific frequency or with a signal detector via a bandpass filter. See sectionTracking mode

Signals from two of the four LNB outputs are tapped off and one fed to the tuner andthe other to the detector. Vertical low is the default LNB output for the detector andhorizontal high for the SatID.

Satellite identificationAfter locking on a satellite the ID-receiver attempts to identify it by matching thetransponder's network identifier code or NID with the antenna's internal list.If the identified satellite is another one than selected, the correct position iscalculated and the antenna automatically repositioned. When a correct match ismade, "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 anothersatellite.

Chapter 2: Functional description

Satellite identification

8 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 longitudeassuming a 0° angle in locations on the same longitude. Compensation forship´s movements is also performed continuously.As some satellite’s polarisation is offset, a provision is made to fine-tune it in the SatIDmenu of the PC-program.

9

Polarisation controlDuring initial NID-scanning, polarisation is set to 0°. If no identification is made, scansare executed on -15° and 15° as well.

If the satellite remains unidentified, the antenna tries to acquire another satellite.

Installation

Antenna locationChoose a location that has an unhindered view of the satellite at the point of lowestelevation. Ideally, a location should be chosen as close to the vessel's centre aspossible while keeping cable lengths to a minimum.If the antenna is placed on a pedestal, care must be taken that it does not flexor vibrate.

The satellite TV antenna's LNB is equipped with a radar filter but to avoid damageto 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.

Radar

It is difficult to give exact guidelines for the minimum distance between a radar andthe antenna because radar power, radiation pattern, frequency and pulse length/shape vary from radar to radar. Further, the antenna is typically placed in the nearfield of the radar antenna and reflections from masts, decks and other items in thevicinity 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 andvertical beam width of up to +/- 15o, the worst interference can be avoid by mountingthe satellite TV antenna at a different level - meaning that the antenna is installedminimum 20o above or below the radar antenna. Due to near field effects the benefitof this vertical separation could be reduced at short distance (below approx. 10 m)between radar antenna and satellite TV antenna. Therefore it is recommended toensure as much vertical separation as possible when the satellite TV antenna hasto be placed close to a radar antenna.

SAILOR®

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

12 Installation

MountingRigid mounting is essential for proper function and parts of the vessel subject to heavyresonant vibrations are unsuitable for satellite TV antenna installation.If pedestals higher than 1 m are used utmost care must be taken to ensure rigidity andthat 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 permanentstrength thread-locking fluid applied.

The minimum acceptable seperation (d min.) between a radar and the satellite TVantenna is determined by the radar wavelength/frequency and the power emitted bythe radar. The tables below show some “rule of thumb” minimum separationdistances as a function of radar power at X and S band. If the d min. separation listedbelow is applied, antenna damage is normaly avoided. “d min.” is defined as theshortest distance between the radar antenna (in any position) and the surface of thesatellite TV antenna.

Tracking modesEach satellite can be assigned a single letter code for tracking mode.

Filter Mode (F)If the selected satellite is marked F in the NID-table, signal detection is made witha level detector sensitive for signals in the low/mid/high part of the IF-band. Defaultis mid-band but the setting can be changed in the tracking section of the service menu.This mode should only be used in special circumstances e.g. if a particular satellitedoes not have any transponders in the frequency band connected to the tuner input.

Tuner Mode (T)In mode T, the built-in satellite tuner is used for level detection. The tuner only lockson to signals with the correct frequency, symbol rate and FEC and is suitable if theNID table contains only one or very few satellites.

Auto Mode (A)In mode A, the Filter Mode is used during satellite searches and Tuner Mode fortracking. Provided that the NID-list contains most of the trackable satellites, this isthe preferred mode.

NID-tablesThe network identifier or NID-code is a number between 1 and 65535 embedded inthe digital data stream. Each transponder has an NID assigned to the networkprovider.The satellite TV antenna uses the NID in combination with symbol rate, frequency andFEC (Forward Error Correction) to identify satellites.

Ideally all satellites in the antenna's range should be identifiable to keep search timesto a minimum.

Keeping a database of all the world's satellites is possible but unpractical as scanningtimes would be very long. It is therefore useful to limit the number of satellites to thosethat are within range, either by using satellite lists specific to a geographical areaor by selecting appropriate satellites in the SatID menu i.e. check marking "In View".

As many satellites have beams directed at different areas, it is possible to enterseveral codes and frequencies per satellite. Using a large number increases the

probability of a correct identification under difficult reception conditions but prolongsthe scanning time as well. It is recommended to limit the number of frequencies/NID'sto 5 per satellite.

Scanning a satellite for NID-codesAltering the satellite list can be done either by loading a new file or editing the existingin the SatID menu.

If the ID receiver is connected to a low-band LNB-output, set LNB frequency to 9750MHz. If it is connected to a high-band output, set LNB frequency to 10600 MHz.

Enter a new satellite by typing name and longitude in the fields below the satellitelist. Check "In view", "Usable" and select tracking mode "A", click "New".Select the satellite by clicking on its name and enter frequencies, symbol rates andNID's in the same manner. If no NID's are known, the satellite can be scanned asfollows:


NID-tables

39

1. Disable the SatID function in the SatID menu.2. Select the satellite in the satellite menu and lock on it manually.3. Return to the SatID menu and click "Scan Sat".4. When scan is completed, select frequencies to be used and click "Add".5. Enable SatID again.

To assist in frequency selection the BER or bit error rate is displayed in the list. A lowervalue indicates a better signal. A BER of 1E-2 (0.01) or higher is poor and a BER of1E-3 (0.001) or lower is very good.

In most cases it is best to limit the satellite search to transponders with a symbol rategreater than 15 Msymb/s. A rate setting down to 3 Msymb/s is possible but scans willbecome slower with decreasing rates.

Satellite list editingAdditions and deletions in the satellite- and transponder list can be madedirectly in the SatID-menu. To facilitate editing of larger files an editing tool canbe accessed from the "Edit Satfile" button.

Scan-all functionA search of the entire sky for satellites can be made using the "Scan All" function.A provision for its use is that the satellite TV antenna can track one satellite usingfilter mode and that it can be identified. The ship also has to be at standstill duringthe scan.Upon activation the satellite TV antenna first scans the original satellite for NID's andthen automatically proceeds to search for other satellites. When the scan is completedthe resulting file can be saved and edited using the editing function.
