800 Mbps TELEMETRY PROCESSING SYSTEMSatellites are becoming more capable and complex, as such their downlink requirements are increasing. In addition, future satellite systems will be operating at Ka-band that provides ample bandwidth to support the increase in downlink rates up to 800 Mbps. This paper describes a new generation commercial solution that can support 800 Mbps telemetry processing for data reception, frame synchronization, time tagging, Reed-Solomon forward error correction, data routing, data storage, data playback for testing, networking, and Bit Error Rate (BER) Testing.
ADAPS TELEMETRY PROCESSOR MID-LIFE IMPROVEMENT PROGRAMThis paper will provide details on planned upgrades to the Advanced Data Acquisition and Processing System (ADAPS) Real-Time / Post Flight Processing (RT/PFP) telemetry processor. The ADAPS RT/PFP is used to process real-time telemetry at the Air Force Flight Test Center (AFFTC). The ADAPS telemetry processor is based on the L3 Communications O/S90 telemetry pre-processing system. New modifications to the ADAPS telemetry processor will provide increased processing capability, increased data throughput, and higher reliability.
LINUX POWERED TELEMETRY PROCESSINGSince its debut, the Linux operating system has garnered much attention in the software development community. This paper discusses the open source operating system, Linux, and it’s application as the operating system powering a commercial off-the-shelf telemetry processing system. The paper begins by discussing what are the real-time requirements of the operating system in a telemetry processing system. A discussion to the Linux system is then presented. Soft real-time features of Linux are discussed which allow it to meet the telemetry processing requirements. Linux is compared with the more traditional operating system products and points are made as to why open source software is just as capable, if not preferable, of handling mission critical applications. The paper also presents the authors’ view of future of Linux and open source software in the telemetry marketplace. The paper concludes with a summary of products available for Linux that support telemetry processing and the data acquisition environment.
