A spaceborne cryocooler produces undesirable micro-vibration disturbances during its on-orbit operation, which is one of the main sources of degradation of the image quality of high-resolution observation satellites.
This paper describes the on-orbit operation and performance of the Micro LabSat ACS.
Finally, its reinstallation on the launch tower and the preliminary result of its on-orbit operation are introduced.
Before the assembly of the Tracker subsystem of the Large Area Telescope (LAT) science instrument of GLAST, every component (tray) and module (tower) has been subjected to extensive ground testing required to ensure successful launch and on-orbit operation.
In this paper, we provide a brief description of both Terra and Aqua MODIS on-orbit operation and calibration activities and present results of on-orbit radiometric, spatial, and spectral characterization.
This chapter provides an overview of optical sensor design requirements and key performance parameters that need to be fully characterized during prelaunch testing and frequently monitored throughout its on-orbit operation.
This paper examines the MODIS performance during more than three years of on-orbit operation together with data from fifteen years of pre-launch development and testing for possible improvements in design choices, practices and procedures that may prove useful in the development of future space-borne multi-spectral radiometers.
In this study, the primary design objective is to develop a passive isolator that can guarantee structural safety of the cooler assembly in a launch vibration environment without a launch locking mechanism, while effectively isolating the cooler-induced micro-jitter during the on-orbit operation of the cooler.
For ISSpresso each requirement was fully met as documented by the verifications submitted to NASA, including those required by the Payload Safety Review Panel (PSRP) to demonstrate compliance with ISS safety requirements for transportation, on-orbit operation, and return or disposal NASA Certification was obtained at the end of 2014.
As a novel and potential supporting technology for on-orbit operation missions, spacecraft electromagnetic docking has not only distinct visible advantages, but also several intrinsic unconspicuous capabilities, such as the self-docking capability which could be exploited to alleviate the burden of the docking controller.
