Background. The object of research is the efficiency of onboard telemetry launch vehicle control systems. The subject of research are methods of improving the efficiency of on-board telemetry system (BRTS). The purpose of research is to conduct a comparative assessment of proposed advanced methods of increasing the efficiency of onboard telemetry systems with existing ones.
Results. To evaluate the proposed methods introduce the concept of efficiency BRTS, which is understood to increase the accuracy adopted in the world of telemetry information (TMI) and reducing consumption of both frequency and power the radio resources. The article compared the characteristics of the existing telemetry systems with system created on the basis of application of these methods. As a result, it shows the feasibility of the second radio communication systems for the organization Launch-Earth.
Сonclusions. The proposed Article methods allow: to increase the accuracy of the adopted TMI and reduce the value of the bit energy-to noise power spectral density through the use of multi-point encoding; to narrow the width of the Nyquist bandwidth through the use of quadrature amplitude modulation.
