Introduction

The design and development of spacecraft requires the use of a variety of tools and technologies, many of which are based on telemetry, remote control information models and exchange formats defined as the basis: During the spacecraft research and development cycle, multiple units and multiple ground systems often work together, and it is necessary to perform operations between these systems:

Data exchange of telemetry and remote control models and formats: If there is no standard for data exchange, telemetry and remote control information need to be processed during each interaction process:

Custom input, format conversion and verification of information are not only heavy workload, but also time-consuming and error-prone:

A typical example is the collaboration between the spacecraft development department and the spacecraft operation and control department: Telemetry and remote control as defined by the spacecraft development department the data format is quite different from that used by ground systems: This resulted in the translation and transcription of the data and the addition of custom software testing quantity, and also increases the probability of error: Standardization of telemetry and telecontrol data definition formats will simplify this process and make it easier to use between different systems:

Enables direct data exchange without the need to develop task-specific database import/export tools: Ideally, for those who follow the same A ground system with standardized telemetry and remote control data, spacecraft operators can very efficiently migrate spacecraft missions from a ground system to another ground system:

Based on the above background, this document standardizes spacecraft telemetry and remote control models and formats to reduce the development, Integration and testing time is reduced, and implementation costs are reduced:
