The invention provides a spacecraft emergency measurement and control device and method based on Beidou No.3 GSMC/RSMC. The spacecraft emergency measurement and control device comprises a short message antenna, a navigation antenna, a pre-amplifier module, a base-band processing module and a power amplifier module; the short message antenna transmits and receives an RDSS signal; the navigation antenna receives an RNSS signal and a B2b signal of the Beidou No.3; the base-band processing module captures, tracks and measures the amplified RNSS signal, extracts a frame time mark signal according to an S frequency point signal and a B2b signal of the RDSS, demodulates the remote control information sent to a short message terminal by a ground command center according to the frame time mark signal, receives the external telemetering data and generates a transmitting signal; and the power amplifier module amplifies the transmitting signal into an L frequency point signal of the RDSS and outputs the L frequency point
