What does DMC 3 stand for in space?
DMC-3 stands for Disaster Monitoring Constellation 3 and represents three high-resolution optical Earth imaging spacecraft owned and operated by DMCii (DMC International Imaging), headquartered in Guildford, UK.
When was the first DMC satellite launched into space?
The first DMC mission was launched in 2002 based on the SSTL-100 satellite bus and operated by Algeria. Other participating nations in the DMC project include Turkey, Nigeria, Spain and the UK, all using SSTL-built satellites.
What kind of satellite is the DMC3 satellite?
The three DMC-3 satellites are based on the SSTL-300 S1 spacecraft platform that builds on the smaller SSTL platforms such as the SSTL-100 and –150 using a number of heritage components in a larger, more-capable platform that can host imaging payloads achieving sub-meter resolution.
Who was the first customer of DMCii satellites?
The first customer to sign with DMCii was 21AT, the Twenty First Century Aerospace Technology Company Ltd. in Beijing, China. Signed in 2011, the contract includes the lease of the entire capacity of the first three DMC satellites with a contract time of seven-years.
How big is the DMC3 satellite in kilograms?
Weighing in at around 350 Kilograms, each DMC-3 spacecraft consists of two major components – a platform assembly hosting the various satellite subsystems and a 150-Kilogram payload assembly that facilitates the optical imaging system and the imager barrel.
What kind of data transmission does DMC3 do?
DMC-3 handles all command uplinks and spacecraft telemetry data downlink via S-Band, hosting a 4-Watt RF Power S-Band Transmitter and a dedicated receiver. The S-Band transmitter can deliver data at rates from 9.6kbps to 8.0Mbps using BPSK or QPSK modulation, accepting data via LVDS.
How many SerDes are in a DMC3 system?
Using HSDR heritage, the system can support 20 LVDS inputs/outputs at a data rate of 150Mbps, 5 SerDes inputs at up to 2Gbps and 16 LVDS outputs at 150Mbps. DMC-3 handles all command uplinks and spacecraft telemetry data downlink via S-Band, hosting a 4-Watt RF Power S-Band Transmitter and a dedicated receiver.
