Abstract
To simplify the complexity of the deep space probe and solve the problem of the balance design between the downlink telemetry and ranging signal under the constraint of the limited power and band-width,a novel telemetry signal ranging method is proposed in this paper based on the regenerative pseudo noise( PN) ranging technique. The PN code is replaced by telemetry data symbol,and the downlink range measurement is realized by tracking telemetry signal at the ground tracking loops to save an independent ranging signal. The results of the analysis and simulation show that the proposed method can simplify the downlink signal and reduce the complexity of the system,and the stochastic ranging error is better than that of traditional method when the telemetry rate exceeds 100 kbit/s. With the higher telemetry rate,the better ranging accuracy can be achieved.关键词
