The SkyLabs NANOsky CMM™ is a software development kit (SDK) for monitoring, controlling and managing any SkyLabs satellite equipment. The SDK comprises of application library and FW module. The SDK offers a fast prototyping and ease integration to third-party software through comprehensive C++ library and application-level examples. The SDK reduces the development time of NANOsky equipment integration to the customer specific AIV/T, EGSE or even MOC software through its application library module. The application library module offers a framework in Qt/C++ for both Windows and Linux environments and supports functionalities of all NANOsky and picoRTU. The C-based FW module offers a standard set of functions for the onboard computer to be integrated into RTOS upon which an application layer functions can be developed. The features of the flight proven FW module: • FW image selection and integrity checks • housekeeping TM acquisition and logging • bootloader • FW update mechanism • CAN-TS and LVDS-TS communication stacks • verified FDIR mechanism • OBT management • emergency mode operation • parameters system • permanent storage subsystem • memory management • redundancy management • software scrubber The NANOsky CMM application library is compliant with following products of SkyLabs: • NANOobc-2, NANOhpm-obc, NANOhpc-obc (with NANOsky CMM FW module) • NANOlink-2 family, NANOcomm-2 • NANOif-2 • NANOeps family, NANOamppt • picoRTU system
