LNB Dish Satellite
Here’s some consideration for people who have installed satellite dishes for their internet or cable TV needs. I suddenly had this thought that perhaps a little geekery is in order. Locally, this applies to Dream Satellite subscribers and to all other satellite dish users as well.
One of the more common question is about LNB. Dish satellite users have often wondered how they would go about and make LNB adjustments to their satellite dish. I did a quick research and here’s one of the more user friendly answer I got is from www.tech-faq.com.
LNB stands for Low Noise Block and it is the receiving end of a satellite dish. The LNB must be pointing directly to the satellite overhead in orbit to receive the strongest and clearest signal. There are many types of satellite dishes available, some of them are installed in a fixed position, others are installed so that they can move on regular basis usually determined by the type of satellite that you would like to receive signals from. As with a normal TV antenna, it may be required for you to adjust the LNB in order to receive the highest quality (strongest and clearest) satellite signals available.
Most satellite TV dishes today use a stationary position to receive all of their television programming. They are called Direct Broadcast Satellite (DBS) or sometimes referred to as direct to TV. These satellite dishes are usually part of a paid service. Two popular services in the United States are DirecTV and Echo Star’s Dish Network.
DBS satellites are installed to be stationary, they point in one direction to receive signals from the satellite which is in geostationary orbit in space. Geostationary orbit means that it is always in the same position in the space due to the same speed of the satellite and earth’s rotation.
Most people only adjust their DBS satellite dishes once, usually when they first install it. However, if the signal is not clear or if the satellite dish has unexpectedly moved or needs to be removed and placed someplace new, you will need to adjust the LNB.

Satellite Internet: What’s Hot & What’s Not!
Hot
Plans are afoot to build several medium-earth orbit (MEO) satellites to serve the other 3 billion people in Latin America, the Middle East, Africa, and Asia who have little or no internet access. The satellite company undertaking this venture is O3B, a reference to the ‘other 3 billion’, who recently linked up with Google and other investors ‘to bring cheaper, high-speed wireless Internet access to areas unlikely to see investments in fiber infrastructure.
MEO what? As its name suggests medium-earth orbit satellites orbit the earth at an altitude of around 5,000 miles compared to its Geosatellite counterparts that do so at around 22,500 miles. As it’s much closer to earth, latency (signal looping time between earth and satellite) is also shorter– around 120 milliseconds.
The plan is for O3B to launch 16 MEO satellite and have these activated by late 2010.

There’s no specifics yet as to which part of Asia will be included in the coverage but I should think that it would no longer cover Southeast Asia as they project it to be covered by the Kizuna satellite.
Not
And speaking of the Kizuna satellite, July & August has come and gone and yet the promise of Kizuna going live by July 2008 has remained just that– a promise. The latest word on the Kizuna is that it is being tested for commercial operations. But that was an eternity ago.
If not for this news about O3B, interest on the Kizuna would have waned completely. It’s somewhat weird that the Kizuna satellite boys are not providing enough regular updates on what’s going on. Is there a problem? What timeline are we looking at now?
Paging JAXA, throw us a little bone over here please?
Kizuna (Winds) Satellite Internet Update
Looks like the Kizuna Satellite Internet project is moving along as planned. According to Jaxa, they have moved the Kizuna to a regular operation phase. A little more longer and this will become a reality for the entire Southeast Asia. Not sure about the Philippines though.
KIZUNA moved to regular operation phase
JAXA has been carrying out the initial functional verification of the onboard equipment of the “KIZUNA” in cooperation with the National Institute of Information and Communications Technology for about three and half months since the KIZUNA was injected into its scheduled geostationary orbit (East longitude of about 143 degrees) on March 14, 2008. After we confirmed that all functions were normal, we completed the checks on all the equipment on June 27. On June 30, a review was held to determine if we should move onto the regular operation phase, and we decided to shift from the initial phase to the regular operation phase.
