Today, an Ariane5 launched the biggest communication satellite ever
built (6.5 tons). According to http://www.arianespace.com, here are the
technical data (achieved, targetted, and tolerance):
Perigee: 574.8 km for a target of 575 km (�3 km)
Apogee: 35,875 km for a target of 35,894 km (�160 km)
Inclination: 6.98 degrees for a target of 7.00 degrees (�0.06�)
(For those who are new to this subgroup: the guidance software of
Ariane5 is entirely in Ada).
