PCM Telemetry Encoder: Telemetry Solutions, Airborne Telemetry Solutions


Pulse Code Modulation (PCM) Telemetry Encoder, designed by Mistral, is used to encode the data in a serial digital format and transmit it on a carrier to another location for decoding and analysis. PCM systems are less susceptible to noise than analog systems. The digital data in a PCM Telemetry Encoder is easier to transmit, record, and analyze.

Mistral’s PCM Telemetry Encoder is an FPGA-based system with Data Acquisition, Conversion, Frame processing, and PCM output section. The system is ideal for analyzing flight parameters in airborne applications. This system has been subjected to an environmental test and has been qualified for an airborne application.

Telemetry is a remote sensing technique wherein parameters such as velocity, altitude, temperature, etc., are measured, and the results are transmitted to a distant station where they are displayed, recorded and analyzed. The transmission media may be air, space, copper wire or fibre cable; depending on the application.
