This book presents a novel satellite timekeeping
system which does not require on-board atomic clocks
as used by existing navigation satellite systems such
as GPS, GLONASS or the GALILEO system. This
concept is differentiated by the employment of a
synchronization framework combined with lightweight
steerable on-board clocks which act as transponders
re-broadcasting the precise time remotely provided by
the time synchronization network located on the
ground. This allows the system to operate optimally
when satellites are in direct contact with the ground
station, making it suitable for a...

KiCad is an open source software suite for electronic design automation (EDA). It facilitates the design of schematics for electronic circuits and their conversion to PCBs (printed circuit board) design. KiCad was orginally developed by Jean-Pierre Charras, and features an integrated environment for schematic capture and PCB layout design. This is a general Getting Started Guide. There are other books in this series for tools like cvpcb, pcbnew, gerbview and more.
