The satellite is based on the SSTL-100 bus. The satellite weighs {{convert|103|kg}} and carries an earth imaging payload with {{convert|12|m|ft|adj=on}} panchromatic imager and {{convert|24|m|ft|adj=on}} multispectral cameras.[4][2] ConstructionThe satellite had high participation from ASAL, with eighteen engineers that worked on assembly, integration, and test. Additionally, at the University of Surrey, 18 students used the satellite as a part of their graduate degree research.[2] LaunchThe satellite was launched on 26 September 2016 into a {{convert|670|km|mi|adj=on}} altitude polar orbit by ISRO using the PSLV-C35 rocket.[5] It was launched with several other satellites. The primary payload was SCATSAT 1, which was launched into a Polar Sun Synchronous Orbit. This was the first time PSLV launched satellites into different orbits. Algeria had three satellites that it will operate launch in that group, which were AlSat-1B, AlSat 2B, and AlSat-Nano. AlSat-2B also had imaging capabilities, but they are higher resolution than AlSat-1B. Of the eight satellites launched by PSLV, five of them were foreign. The remaining satellites were BlackSky Pathfinder 1, Pratham, PISat, and CanX 7.[3][4] Alsat-1B uses three body mounted solar panels for power generation, and a 15 Amp-hour Li-Ion battery for power storage. It uses warm gas, butane powered resistojets for propulsion.[3] The attitude control system uses sun sensors and magnetometers.[6] References1. ^1 {{cite web|url=https://www.sstl.co.uk/Missions/Alsat-1B-Launched-2016|title=Mission|website=Surrey Satellite Technology Limited|access-date=2016-10-30}} {{Portal|Spaceflight}}{{ASAL}}{{Orbital launches in 2016}}2. ^1 2 {{cite web|url=https://www.sstl.co.uk/Missions/Alsat-1B/Alsat-1B/Alsat-1B--The-Mission |title=Alsat-1B satellite mission |website=Surrey Satellite Technology Limited |date=2014-07-10 |accessdate=2016-09-27}} 3. ^1 2 {{cite web|url=http://space.skyrocket.de/doc_sdat/alsat-1b.htm |title=AlSat 1B |publisher=Gunter's Space Page |date=2014-07-10 |accessdate=2016-09-27}} 4. ^1 {{cite web|first1=William|last1=Graham |url=https://www.nasaspaceflight.com/2016/09/isro-pslv-scatsat-1-launch/ |title=ISRO PSLV conducts SCATSAT-1 launch |publisher=NASASpaceFlight.com |date= |accessdate=2016-09-27}} 5. ^{{cite web|url=http://indianexpress.com/article/opinion/web-edits/pslv-c35-launch-double-orbit-satellite-deployment-boosts-isros-commercial-prospects-3050686/ |title=PSLV-C35 launch: Double orbit satellite deployment boosts ISRO’s commercial prospects |publisher=The Indian Express |date=1976-09-27 |accessdate=2016-09-27}} 6. ^{{cite web|url=http://spaceflight101.com/pslv-c35/alsat-1b/|title=AlSat-1B|access-date=2016-10-30|website=Spaceflight101.com}} Related articlesAlgeria national space programs 4 : Spacecraft launched in 2016|Earth observation satellites|Satellites of Algeria|Spacecraft launched by PSLV rockets |
