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). 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. 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. 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. 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.
