The Assumption of the TT&C and Management for SIN Based on TDRS SMA System.

In recent year, the transmission of spatial information present the characteristic of amount users, broad coverage area, multiple service, and convenient access, which make research focus for SIN (spatial information network) users in the area of intelligent TT&C (telemetry, tracking and command) and management. Based on the deep analysis of TDRSS (Tracking and Data Relay Satellite System) application modes, an assumption of TT&C and management for SIN based on the TDRS SMA (S-band Multiple Access) system is proposed. Analysis is mainly focused on the panoramic beam, system composition and user access, also the protocol architecture, communication workflow, and TDRS terminal are original designed. Compared to traditional operational mode, the proposed assumption could realize ubiquitous perception, random access, on-line management, and satellite-ground cooperation for users' application. Relevant result could be referenced in the study of TT&C and management for SIN.
