Consultative Committee for Space Data Systems. Report Concerning Space Data System Standards. Telemetry Summary of Concept and Rationale.
Abstract
The purpose of a telemetry system is to reliably and transparently convey measurement information from a remotely located data generating source to users located in space or on Earth. Typically, data generators are scientific sensors, science housekeeping sensors, engineering sensors and other subsystems on board a spacecraft. The advent of capable microprocessor based hardware will result in data systems with demands for greater throughput and a requirement for corresponding increases in spacecraft autonomy and mission complexity. These facts, along with the current technical and fiscal environments, create a need for greater telemetering capability and efficiency with reduced costs. Traditionally, most of the telemetry resources used by a science mission have been wholly contained within a cognizant Project office and, with the exception of the tracking network, are completely dedicated to that mission. The lack of effective standardization among various missions forces the 'multi-mission' tracking network to implement the lowest level of telemetry transport service, i.e., bit transport. Higher level data delivery services, oriented more toward computer-to-computer transfers and typical of modern day commercial and military networks, must be custom designed and implemented on a mission-to-mission basis.
