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).{{Cite web|url=https://www.n2yo.com/satellite/?s=40147|title=Technical details for satellite MEASAT 3B|website=N2YO.com - Real Time Satellite Tracking and Predictions|access-date=2017-10-03}} 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.{{Cite web|url=http://www.aerospace-technology.com/projects/measat-3b-communication-satellite/|title=MEASAT-3b Communication Satellite|website=Aerospace Technology|access-date=2017-10-03}} 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.{{Cite web|url=http://spaceflight101.com/spacecraft/measat-3b-jabiru-2/|title=Measat-3b (Jabiru 2) – Spacecraft & Satellites|website=spaceflight101.com|language=en-US|access-date=2017-10-03}}{{Cite news|url=http://danielmarin.naukas.com/2014/09/13/lanzamiento-de-la-mision-va218-del-ariane-5-measat-3b-y-optus-10/|title=Lanzamiento de la misión VA218 del Ariane 5 (Measat-3b y OPTUS 10) {{!}} Astronáutica {{!}} Eureka|work=Eureka|access-date=2017-10-03|language=es-ES}} 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.{{Cite web|url=http://space.skyrocket.de/doc_sdat/measat-3b.htm|title=MEASAT 3b (Jabiru 2)|website=space.skyrocket.de|access-date=2017-10-03}} 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.
