At the panel there is "v" for velocity and "a" for altitude. Does anyone know what "s" means? Probably something French?

Don't know what it stands for, but it is the inclination.

"S" is for "Site".

Don't know what it stands for, but it is the inclination.

"S" is for "Site".

Is that the difference between expected and real inclination? Because the're normally flying into 5° or 2° incl. orbits.

And what does "Site = 0 deg" mean?

Another successful Arianespace launch: HOT BIRD™ 9 and W2M in orbit
Kourou, December 20, 2008

http://www.arianespace.com/news-press-release/2008/20-12-08-HOTBIRD9-W2M-launch-success.asp

On Saturday evening, December 20, Arianespace orbited two communications satellites for the European operator Eutelsat: HOT BIRD™ 9 and W2M.

42nd Ariane 5 launch, 28th success in a row, 6th launch in 2008
The latest successful launch of an Ariane 5, the sixth in 2008, confirms that Arianespace’s launch Service & Solutions continue to set the global standard for the major space communications operators and manufacturers.

Ariane 5 is the only commercial heavy launcher in service today capable of simultaneously launching two payloads.

This was the 42nd launch of an Ariane 5 and the 28th successful launch in a row.

Two satellites for one prestigious customer


Arianespace offers the best choice of launch solutions to meet the specific requirements of today’s leading operators.

Arianespace and Eutelsat have teamed up very successfully for over 25 years, with the Ariane launcher lofting more than half of Eutelsat’s fleet. HOT BIRD™ 9 and W2M are the 22nd and 23rd Eutelsat satellites launched by Arianespace.

Following the successful launch of HOT BIRD™ 7A in 2006, Arianespace is proud of its role in bolstering Eutelsat’s flagship orbital position at 13 degrees East. Arianespace is scheduled to launch on February 12, 2009 another Eutelsat satellite, HOT BIRD™ 10.

HOT BIRD™ 9/W2M mission at a glance


The mission was carried out by an Ariane 5 ECA launcher from Europe's Spaceport in Kourou, French Guiana. Liftoff was on Saturday, December 20, 2008 at 7:35 pm local time in Kourou (5:35 pm in Washington, D.C., 22:35 UT, 11:35 pm in Paris, and on Sunday, December 21, at 1:35 am in Moscow, and at 7:35 am in Tokyo).

 HOT BIRD™ 9 was built by Astrium as prime contractor, and weighed 4,880 kg at launch.

Designed to transmit television programs to cable and satellite households in Europe, the Middle East and North Africa, HOT BIRDTM 9 is fitted with 64 high-power Ku-band transponders, increasing the company’s operational redundancy at its flagship orbital position of 13 degrees East. HOT BIRDTM 9 is the second in a series of three identical satellites intended for this orbital position; the third satellite, HOT BIRDTM 10, will be launched by Arianespace in 2009.

The W2M satellite was built by a consortium comprising Astrium and the Indian Space Research Organization (ISRO).

Weighing 3,463 kg at launch, W2M will operate up to 30 transponders. It offers a design life of 15 years.

W2M will allow Eutelsat to offer a wide range of services, including TV broadcasting, data network feeds and broadband access. In addition to fixed-beam coverage of Europe, North Africa and the Middle East, it will include a steerable beam for coverage of islands in the Indian Ocean.

Two Eutelsat satellites are orbited by Arianespace on Ariane 5's 28th consecutive successful mission
December 20, 2008

http://www.arianespace.com/news-mission-update/2008/554.asp

Arianespace today completed its ninth year of Ariane 5 operations with another successful dual-payload mission of the workhorse commercial vehicle, orbiting two telecommunications satellites for Europe’s Eutelsat telecommunications operator.

The heavy-lift Ariane 5 ECA lifted off from Europe’s Spaceport in French Guiana and deployed its HOT BIRD™ 9 and W2M passengers during a 32-minute flight.


Payload lift performance for tonight’s launch was approximately 8,340 kg. for the combined weight of the two satellites. 

It brings the total payload mass lofted by Ariane 5’s six missions in 2008 to more than 56,700 kg. – including the 10 civilian and defense telecommunications spacecraft carried to geostationary transfer orbit, as well as the large Jules Verne Automated Transfer Vehicle (ATV), which was placed in a 260-km. circular orbit to service the International Space Station.

This flight was Ariane 5’s 28th consecutive successful mission, demonstrating that “launcher performance, reliability and availability can go hand-in-hand,” said Jean-Yves Le Gall, Arianespace’s Chairman & CEO during post-launch comments at the Spaceport.

“Tonight’s success also underscores the quality of relationship that unites us with Eutelsat, which entrusted us with the simultaneous launch of two of its satellites – and I want to very warmly thank Giuliano Berretta [the CEO of Eutelsat Communications], for his trust,” he added.  “In 2008, we marked the 25th anniversary of our cooperation this year – with HOT BIRD 9 and W2M being the 22nd and 23rd satellites launched by Arianespace for Eutelsat."

Berretta, who was speaking from Paris, congratulated Arianespace for this double success in support of his company’s telecommunications satellite fleet.  “I hope everyone admired this absolutely beautiful liftoff of Ariane and the separation of our two spacecraft.  I would really like to thank Mr. Yves Le Gall for the great successes of the Ariane launcher.”

A smooth climb-out and on-target deployment sequence

During tonight’s mission, ground tracking cameras followed the Ariane 5’s initial trajectory as the launch was broadcast live on www.arianespace.com.  The good visibility over French Guiana provided a view of Ariane 5’s ascent through scattered clouds, followed by the separation of its two solid boosters – which occurred 2 min. 20 sec. into the flight at an altitude of approximately 64 kilometers.

HOT BIRD 9 was installed in the upper position of Ariane 5’s dual payload “stack,” and it was deployed first during the mission sequence at approximately 27 minutes into the mission.  The spacecraft was produced by EADS Astrium and carries 64 Ku-band transponders for the broadcast of digital and new high-definition TV channels, as well as interactive services.   It will be located at Eutelsat’s premium video neighborhood orbital slot of 13 deg. East, providing a coverage area extending throughout Europe, as well as to North Africa and the Middle East. 

The W2M satellite, which was carried in Ariane 5’s lower passenger slot, was built by a European-Indian joint effort involving EADS Astrium and ANTRIX (the commercial arm of the Indian Space Research Organisation).  This relay platform was separated from the launcher at just over 32 minutes into the flight.  W2M will be positioned at an orbital slot of 16 deg. East, and is to provide both television and radio broadcasting services for Eutelsat.

This evening’s mission was the 42nd for Ariane 5, which made its first liftoff in 1996.  Arianespace began commercial operations with the launcher on December 10, 1999.

Following the successful launch, Le Gall confirmed that Arianespace is continuing to maintain its market leadership, announcing the signature of two additional Service & Solutions orders: one with U.S. manufacturer Lockheed Martin Commercial Space Systems for the launch of Japan’s BSAT-3c/JCSAT-110R; and the other with EADS Astrium to orbit the SSOT (Sistema Satelital para Observación de la Tierra) Earth observation satellite for the government of Chile.

 “Thanks to the work of each and every member of the Ariane team, Arianespace remained the preferred launch company in 2008,” Le Gall said.  “This year is finishing very well, with our six Ariane 5 missions launching half of all the commercial satellites orbited worldwide in 2008; and Arianespace winning 12 of the total 16 contracts signed this year.”

Arianespace will continue its sustained launch pace in 2008, with the first flight in the New Year planned for February 12.  This will use another heavy-lift Ariane 5 ECA version, and is to carry Eutelsat’s HOT BIRD™ 10 along with the NSS-9 satellite for SES.  In addition, the upcoming launch will orbit two Spirale auxiliary payloads – which are demonstrators for a space-based defense optical early warning system.

And what does "Site = 0 deg" mean?

Just checking up on their archived videos, one of them said it was the angle between the vehicle antenna and the tracking station.
