Portable monopulse tracking receiver

Telemetry, Tracking and Command system is one of the most important subsystems in a launch vehicle. Without TTC system there can be no communication link between Launch vehicle and Ground Station. Usage of available digital radio components, signal processing hardware, digital interface technologies, techniques such as direct intermediate frequency sampling, direct digital down conversion and reconfigurable logic enables us to replace traditional rack and stack Ground Stations with more flexible and compact portable configurations. Main functions such as carrier locking, symbol tracking, data demodulation, beam tracking, AGC processing and filtering can be carried out in digital domain. The general design philosophy for Portable Telemetry Ground Station (PTGS) is to take advantage of these possibilities, thereby reducing analog hardware requirements. The advantages of realizing a Portable Telemetry Ground Station (PTGS) for accessing telemetry data from launch vehicles, using such an approach are as follows; Portability, Programmability, Modularity, Low- cost, Flexibility, Easy manufacturability.
