Summary
MEASAT-3b is a communications satellite which MEASAT Satellite Systems operates in geosynchronous orbit at 91.5 degrees east longitude, co-located with MEASAT-3 and MEASAT-3a, with orbital period of 1436.1 minutes and orbital speed of ~3.08 km/s (~1.914 mi/s).[1] It was built by Astrium (now Airbus Defence and Space), based on the Eurostar spacecraft platform, with an investment of approximately MYR1.25bn ($370m), and the 5th MEASAT satellite in orbit.[2] Its weigh 5,897 kilograms at liftoff and is 6.6 by 2.8 by 2.3 meters in dimensions in its stowed config and spanned across 39.4m in orbit.[3][4] It is three-axis stabilized and has 48 Ku band transponder, more than double the current Ku-band capacity operated by MEASAT, which are used for the expansion of video and data services and enhances support to Asia's premium direct-to-home (DTH) and video distribution neighbourhood across Malaysia, South Asia (India), Indonesia and Australia, serving more than 18 million households. It has been designed to support a fourth market.[5] Australian satellite operator NewSat Ltd. (now part of SpeedCast Australia Pty Limited) announced in February 2012, that an undisclosed number of Ku-band transponders will be leases and marketed as Jabiru 2. Its mission duration lasted more than 15 years. MEASAT-3b technical frequency EIRP test are available in LyngSat website.[6]
