International Telemetering Conference Proceedings / October 17-20, 1994 / Town & Country Hotel and Conference Center, San Diego, California / The design of a telemetry tracking system is generally centered around its desired RF
performance which is typically specified in terms of beamwidth, gain and/or G/T.
These parameters determine the size of the reflector used in a given application and
consequently dictate the required size and performance of the associated pedestal.
Any subsequent improvement in the RF performance of such a system is primarily
achieved by increasing the size of its reflector. The magnitude of the improvement
realized is therefore limited by the load handling capability of the pedestal. In most
instances, the substitution of a larger reflector with its increased inertia and wind
loading causes a significant degradation in the dynamic performance of the tracking
system.
This paper describes how the figure of merit (G/T) of a specific dual axis telemetry
tracking system can be improved by a minimum of 7.3 dB/K° without impacting its
dynamic performance or increasing its weight.
These impressive results are made feasible by the innovative pairing of a unique
design planar reflector with a novel implementation of the conical scanner technology.
The FLAPS™ reflector incorporates a newly developed concept which features
lightweight construction and very low wind load coefficients [1, 2]. The conical
scanner is a lightweight version of the DECS tracking feed system described in the
referenced technical paper [3].
