PARIS โ€” Lockheed Martin Space Systems has won an arbitration dispute with satellite fleet operator SES of Luxembourg over a Lockheed-built commercial telecommunications satellite with a slight antenna anomaly, SES said Sept. 22.

The dispute arose when SES discovered that one of its Lockheed-built A2100 satellites in orbit could not receive uplinks at the edge of one of the satelliteโ€™s beams. SES had said the defect prevented the satellite from meeting contracted performance specifications, and that it would withhold a portion of orbital incentive payments to Lockheed as a result.

According to SES, Sunnyvale, Calif.-based Lockheed countered that SES never intended to use the beamโ€™s uplink capability in this way, and so the performance incentive should be paid in full.

โ€œWe lost in binding arbitration and we have settled the matter,โ€ SES said. โ€œIt is now closed.โ€

Satellite builders and owners often include in their contracts that in the event of a dispute, both sides will submit to the judgment of an arbitration panel and agree that the panelโ€™s decision will not be appealed.

SES declined to disclose the size of the orbital incentive payment, but one industry official said it was around $10 million.
