MQ-9 Reaper Space Optical Link: US defence and nuclear giant General Atomics Electromagnetic Systems (GA-EMS) Wednesday said that it has been awarded a contract by the Space Development Agency to demonstrate space-to-air optical communication using GA-EMS’ Laser Interconnect and Networking Communication System (LINCS) and a MQ-9 Reaper drone manufactured by General Atomics Aeronautical Systems (GA-ASI).
The company said the contract was in conjunction with an upcoming experiment where GA-EMS and SDA would partner to launch the LINCS system and conduct a series of experiments demonstrating space-based optical communication starting later this summer.
“This space-to-air experiment is one of the first steps to validate the use of optical communication to provide low latency, secure data directly to weapons and warfighters operating in theatre, a key enabler for Joint All-Domain Command and Control,” Scott Forney, President of GA-EMS, said in a statement sent to Defence Star.
Forney said the award demonstrated the efficacy of GA-EMS’ optical communication technology to support the full requirements of the National Defense Space Architecture.
For the experiment, GA-EMS will use the company’s internally developed LINCS spacecraft – two 12U cubesats each hosting a C-band dual-wavelength full duplex Optical Communication Terminal (OCT) and an Infrared (IR) payload – to communicate with a GA-EMS OCT integrated on an airborne GA-ASI MQ-9 unmanned aircraft.
The spacecraft will operate in low earth orbit and will communicate with the MQ-9 flying at approximately 25,000 feet.
“Optical communication to an air, ground, or maritime asset proposes a different set of challenges than space-to-space communication, because you have to account for distortions to the optical beam caused by atmospheric elements like weather, clouds, dust, and even wind,” explained Nick Bucci, Vice President of Missile Defense and Space Systems at GA-EMS.
“GA-EMS has invested significantly in enabling technologies, including adaptive optics that compensate for such distortions, to allow our OCTs to provide two-way, low latency, high-bandwidth, secure communication to warfighters in whatever domain they operate,” Bussi said.
