Coursework covers the essentials required to perform an iDirect or Galileo satellite installation, including activation of a system for full use.

Ground Control has a world-wide network of certified VSAT installers capable of simple or complex, fixed and mobile installations. Here's what you can expect when you work with Ground Control for your satellite dish installation. Leasing may include installation costs, and in some cases annual service costs.

Our leasing may also include equipment from other sources not directly sold by us, which is often helpful to organizations purchasing for a larger project. If you have an existing Ku-Band satellite system using iDirect equipment, switching may be as easy as calling us.

In some cases we may need to repoint your dish or upgrade the transmitter using a local technician. Then move it fractionally up or down to get the best link margin value. Wait until the parameters have stabilised. Repeat these steps several times. Then tighten the screws.

Sometimes tightening the screws will de-point the dish again. You may have to try several times. If you suspect such a case, then you can use the transponder parameters on the Astra satellite shown in table 4 below.

When a satellite dish is facing towards a satellite at due south, the plane of the LNB will be vertical straight down. As the dish is moved around either East or West to receive other Satellites the LNB will need to be tilted rotated , clockwise for West and counter clockwise for East as viewed from the rear of the dish.

The best way to adjust the LNB skew is to set it at zero degree and then to rotate it in very small steps both ways while keeping an eye on the link margin. Adjust for optimal link margin. Note: If the user satellite dish is within the specification the measured clear sky link margin should be more than 4 dB for Ku band and more than 2.

This section describes the installation and pointing of a dual feed system, in order to be ready for reception from the EUMETCast backup transponders on HB A curved rail is recommended, such that all LNBs point to the centre of the dish. In Figure 11 the standard 40mm LNB mounts are used. After this procedure the E10A performance should close to the original performance, and in addition reception from HB13 should be possible.

This section describes the impact of pointing errors on the link margin. The requirements for mobile reception systems are exactly the same as for fixed antenna systems. An implicit requirement is of course that the pointing accuracy must be maintained good enough to prevent a significant degradation in the link margin.

See antenna size plots in Antenna size recommendations for more details. From this the pointing accuracy for a 2. Table 5: gain loss versus pointing error.

The LNB is a crucial analogue component for reception of the weak satellite signals in Ku band and for delivering the down-converted L-band signal to the DVB receiver. The LNB should also match the antenna geometry. The noise figure of the LNB is a measurement of how much noise the LNB will add to the signal you may be intending to receive.
