Hi All,
I was doing a Google search for the phone number for the Napa teleport so that I could contact an old friend, and I came across this old thread. If this thread is still active, I'll give some answers.
The Napa satellite earth station teleport is owned by Intelsat. It was originally built by PanAmSat in order to service their satellites in the Pacific Ocean Region (POR). PanAmSat was sold and then merged and merged again until today the teleport is owned by Intelsat.
In the photos shown previously in this thread, the antennas looking straight up (zenith position), are in that configuration for maintenance, and are out of service. The teleport can view satellites in the POR, the U.S. domestic arc and a couple of satellites in the AOR (Atlantic Ocean Region). This teleport services many satellites, including Intelsat 8, which is located at 166°E (on the other side of the International Dateline), with a look angle of 5.7° above the horizon.
The Richmond satellite earth station teleport is owned by ABS-CBN International. ABS-CBNi is a U.S. corporation that is a wholly owned subsidiary of ABS-CBN Broadcasting of the Philippines. ABS-CBN Broadcasting is the largest television network and media conglomerate in the Philippines. The TV network is on par with ABC, CBS & NBC in size and production capability.
The Richmond teleport was originally constructed with one 11 meter antenna by Argo Communications in 1984. In 1989 the teleport's assets were sold to Spectrum Satellite, Inc., a small independent startup company. Spectrum Satellite over the years expanded the teleport property and number of antennas until being sold in 1998 to Loral Skynet, who at that time was the owner of the Telstar fleet of satellites. Not much happened over the next 8 years until Loral declared bankruptcy and sold most of the Telstar fleet to Intelsat. In March of 2006 Loral sold the Richmond teleport to its then largest customer, ABS-CBNi.
At the Richmond facility, the trains don't bother the services on the antennas. Even though it doesn't look like it, the antennas with the lowest look angles are set back from the railroad tracks so as to be able to shoot over the trains.
Those of you in Northern California who might be interested in touring the Richmond facility, I might be able to arrange it, as I still have close contacts there.
