The invention discloses a low-power-consumption missile-borne recording device suitable for a cross-medium navigation body. The low-power-consumption missile-borne recording device comprises a shell, a sealing cover and a PCB. The shell is used for fixing the PCB and is sealed in a waterproof mode through the sealing cover. A three-axis acceleration sensor, a main control chip, a storage chip, a power supply chip, a resettable fuse and three function keys are arranged on the front surface of the PCB; a slide switch and a battery compartment are arranged on the back; the battery compartment is used for mounting a button battery; the three-axis acceleration sensor, the storage chip and the power supply chip are all connected with the main control chip, the resettable fuse is connected with a Schottky diode and then is connected to the input end of the power supply chip, the resettable fuse is connected with two capacitors in parallel, and the other end of the resettable fuse is connected with the output end of a power supply; the three function keys are respectively connected with two GPIO (General Purpose Input/Output) ports and an NRST external reset port of the main control chip; and two fixed ends of the slide switch are respectively connected with the battery and the pin of the pin header for supplying power so as to switch the power supply. According to the invention, the data recording requirement of the cross-medium navigation body can be met.
