AMC- to SES- Satellite Transition Scheduled for June 7, 05

As you know, Microspace Communications Corporation provides satellite services for your network in North America via the satellite known as AMC-1. AMC-1 is owned and operated by SES World Skies (SES). While AMC-1 continues to operate properly, it is approaching its end-of-life due to fuel requirements. SES successfully launched the replacement satellite in July, 2011. That replacement satellite is named SES-3 and a firm date for the transition to SES-3 is June 7, 2015.

No Frequency Reassignment:

Often times in such a satellite transition there are frequencies (customer channels) that need to be reassigned. For your network there will NOT be any frequency changes when the SES-3 satellite is deployed.

Polarization Change:

There is a 26 degree polarization difference between the two satellites. Microspace has been recommending that when your company installs new locations and/or is performing maintenance at the downlink antenna locations, you can minimize the impact of this polarization change by setting the LNB polarization 13 degrees away from optimum. This LNB offset adjustment will prevent any adjustments from having to be made following the transition date. Microspace has created a video about the polarization change, and you can view it anytime on the Microspace website at: http://microspace.com/satellite-transition/

Activities at the Actual Time of the Transition:

Simply stated, you and your customer sites will NOT have to perform any actions, assuming the polarization adjustments recommended by Microspace were followed.

So you know, the current Microspace uplink transmission will be transferred to our in-place backup antenna, which will have been calibrated, including the polarization change, for the new satellite. After recalibrating our primary uplink antenna and transmission systems, we will transition all traffic onto that primary uplink antenna.

These described transitions will occur in milliseconds, therefore we are not anticipating any downtime during this transition.

Benefits of the New Satellite SES-3:

From a daily operational standpoint, you should expect a highly reliable and available signal from SES-3 at your downlink locations in North America. The satellite's higher power levels will provide additional rain-fade margin, presuming properly aligned antennas.

The new SES-3 satellite is expected to have improved adjacent satellite performance and it has a larger footprint than its predecessor.

Additionally, since SES-3's operational life is expected to exceed 15 years, you and your customers are on a very stable, long-term delivery platform.
