Malaysia’s Measat-3 satellite tumbling in GEO

This text was up to date July 17 with an replace from Measat.

TAMPA, Fla. — Malaysian operator Measat introduced July 17 it has maintained steady telemetry and command management of an growing old satellite tv for pc that ExoAnalytic Options, an area monitoring firm, stated has been drifting westward in geostationary orbit for almost a month.

The ExoAnalytic area monitoring system detected an anomaly for Measat-3 on June 21, after which it began drifting out of its 91.5 East orbital slot. 

Measat-3 seems to have made a number of in-orbit maneuvers after starting to float June 22, however “none since our analysts confirmed on July 1 that it was tumbling,” stated ExoAnalytic Options govt vp of engineering Invoice Therien.

“It’s uncommon to see one come again from this stage,” Therien informed table4 July 17.

Nevertheless, he added it was attainable that Measat remains to be in a position to talk with and get better the Boeing-built satellite tv for pc, which was nearing the top of its operational life after launching in 2006.

Measat stated Boeing is conducting an in-depth investigation to find out the basis reason for an anomaly on Measat-3, which is insured.

The operator introduced June 26 that an anomaly it detected June 21 had been resolved, and its crew had been in full management of Measat-3 for about two days.

However June 27 it stated in an announcement: “In the course of the course of our monitoring of restored satellite tv for pc providers after a latest anomaly incident on MEASAT-3, we have now noticed that the degrees of intermittent service degradation recorded point out that further time shall be required to completely full the advanced satellite tv for pc and sign stabilisation course of.” 

U.S.-based ExoAnalytic Options noticed no particles round Measat-3 when it began drifting and stated there is no such thing as a near-term collision threat with one other object in area.

“As satellites age, drifting from orbit is a pure phenomenon,” stated Stewart Bain, CEO of Canadian firm Northstar, which is planning a satellite tv for pc constellation to trace different satellites. 

“MEASAT-3 is a extra excessive case. As we more and more commercialize area, examples like this spotlight how vitally vital it’s for our financial system to have exact data on resident area objects in actual time in order that different excessive worth area property might take mandatory evasive maneuvers or just keep the place they’re.”

Measat-3 lined Asia, Australia, Southern Europe, Africa and the Center East with C-band and Malaysia, Indonesia and South Asia with Ku-band providers.

The operator stated it was in a position to instantly migrate and restore broadcast providers on different satellites in its fleet after the satellite tv for pc bumped into points.

“All of the MEASAT-3 transponders have been deactivated to forestall interference with different satellites,” it stated July 17. 

“MEASAT has additionally knowledgeable Mixed House Operations Centre (CSpOC) by way of House-Monitor to trace the MEASAT-3 satellite tv for pc and notify different operators of the satellite tv for pc’s orbital location, whereas the total investigation is being carried out by MEASAT and [Boeing Satellite Systems]. A report on the result of the investigation shall be launched in the end.”

Measat stated in Could 2019 that Airbus Defence and House will construct a Measat-3 alternative referred to as Measat-3d in time for a 2021 launch.

Measat-3d can also be because of successfully substitute one other growing old satellite tv for pc referred to as Measat-3a, which launched in 2009.

Together with Measat-3, Measat operates 5 satellites that present broadcast and telecoms providers.
