The invention discloses an embedded atmospheric data sensing system. The system comprises a number of pressure measuring structures, pressure sensors, a solution circuit unit, a power supply, a control serial port and a telemetry serial port, wherein the number of the pressure sensors is equal to the number of the pressure measuring structures. Each pressure measuring structure is connected with the corresponding pressure sensor through an air duct. The solution circuit unit is connected with a number of pressure sensors. The power supply is connected with the solution circuit unit. The control serial port and the telemetry serial port are connected with the solution circuit unit respectively. According to the invention, airflow signals and temperature signals of the aircraft surface can be measured in real time, and flight atmospheric data are solved in real time; the measurement is accurate; and information is timely fed back.
