Preferred term

GA-EMS OTB-2  

Definition

  • In September 2018 NASA awarded the contract for hosting the MAIA instrument to General Atomics Electromagnetic Systems (GA-EMS). The instrument will fly on the GA-EMS Orbital Test Bed (OTB)-2 satellite. GA-EMS will install the MAIA instrument on their OTB-2 satellite, perform pre-launch testing to prepare the integrated system for operation in space, and operate the satellite once it is launched into Earth orbit. Launch is currently planned for 2022. The OTB-2 is a larger version of GA-EMS’ OTB-1 spacecraft, which will carry JPL’s Deep Space Atomic Clock into Earth orbit. The larger size and enhanced capabilities of OTB-2 are needed to accommodate the MAIA instrument and its high speed data link. Three deployable solar panels and two additional solar panels attached to the spacecraft body will provide electrical power. (en)
