专利汇可以提供Telemetory transmission system for artificial satellite专利检索,专利查询,专利分析的服务。并且PURPOSE:To improve the overall transmission efficiency, by selecting a plurality of physical quantities at the inside of an artificial satellite with a command from an earth station in advance and transmtting either one of the physical quantities in response to the command from the earth station. CONSTITUTION:A main frame 1 of digital telemetory is constituted in 64 words and the designation of word is sequentially to the frame 1 with the 1st, 2nd 3rd words 2, 3, and 4. Words 6-10 are taken as the items of data of transmission device at the step of steady state. Terminals 12-19 of a rotary switch 11, as a sampling mechanism of the telemetory, are connected for a prescribed time to sample an input signal. The terminal 12 is connected with a normal analog signal, the terminal 13 is with sampling points 15 and 16 of the telemetory, and the terminals 18 and 19 are connected with exciting terminals of a relay. The sampled signal is digitized at an A/D converter 20, a telemetory output 23 is outputted from a digital synthesis circuit 21, and any physical quantity is outputted in response to the command from the earth station.,下面是Telemetory transmission system for artificial satellite专利的具体信息内容。
