Abstract
This paper presents a rocket recovery system logger program. The equipment mainly used in the recycling system of the missile-borne solid state memory. As the signal transmitter, the Beacon is set under the memory of the rocket, sending GPS information real-time when the memory falls down to the ground. For the ground recovery system, we can dispose the specific location of each node based on the topography by calculating the landing area of the beacon. A beacon transponder is placed on each node and each beacon transponder of the node can better receive signal and transmit it to the control center correctly. Every beacon transponder has only one corresponding MAC address, so the control center can distinguish which one is sending signal. This paper designs the framework of the network nodes and the transmission of the physical model, it also analysis the signal transmission system problems such as the high dynamic Doppler effect, the theoretical analysis and experimental verification. The experiment demonstrates that the network node is a particular promising approach in wireless transmission technologies.
