High Performance Modulations for Telemetry (HYPERMOD)

New airborne data systems, such as the Common Airborne Instrumentation System (CAIS), can generate instrumentation data at rates up to 50 Mbps - this far exceeds the transmission capacities of current telemetry equipment. In effect, there is more information available than can be relayed to the ground. The asing the transmission bandwidth of the telemetry system, is no solution at all - the spectrum is already fully utilized. It is therefore imperative that more efficient transmission techniques be employed.There are several areas in which new technologies can be applied to increase telemetry system throughput. Data compression, forward error correction, high-order modulations, and dynamic multiple access techniques can make better use of the available spectrum. The proposed program, High performance Modulations for Telemetry (HYPERMOD), focuses on more efficient modulation techniques, and the hardware and software which implement the modulation. The HYPERMOD program meets the challenge of increasing telemetry data throughput by providing a system-level data throughput of at least 2 bps/Hz, accounting for multiple channels operating in a densely packed spectrum -Nova's design will result in detailed waveform specfications; subsequently,the system will be fully simulated to validate the proposed performance improvements.
