Embodiment Construction

[0089] The specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0090] An adaptive networking method suitable for small satellite clusters includes the following steps:

[0091] (1) Phase 1: Launch into orbit

[0092] Step 1: Determine the way of launching small satellites into orbit: There are two ways of entering into orbit. The first method is launching satellites into orbit one by one; the second method is launching multiple satellites into orbit with one arrow;

[0093] Step 2: Determine the boot sequence; the method for determining the boot sequence is as follows:

[0094] (A) If the satellite is launched into orbit one by one, when the satellites are turned on after they are in orbit, the network communication components will start to work for networking, which is defined as the networking mode of turning on successively;

[0095] (B) If multiple satellites are launched into orbit with one arrow, w...

Abstract

The invention discloses an adaptive networking method applicable to small satellite clusters. A centralized resource distribution and distributed routing combined mode and a time division multiple access and random competition combined access process are adopted in the adaptive networking method, and specific information frame formats and contents are defined and designed and are matched with the designed adaptive networking method for the small satellite clusters. The adaptive networking method includes stages of 1, performing small satellite launching and orbit injection; 2, performing initial networking in a successive starting-up networking mode and a simultaneous starting-up networking mode; 3, building and maintaining dynamic routes of networks and finally implementing adaptive networking for the small satellite clusters. The adaptive networking method has the advantages that the problem of conflict between quick networking and adaptive and flexible networking for distributed satellite systems can be effectively solved, and the adaptive networking method is high in pertinence and adaptability to special application scenes and characteristics of distributed satellite systems.

Description

Technical field [0001] An adaptive networking method suitable for small satellite clusters of the present invention belongs to satellite network technology, especially the field of satellite formation networking. Background technique [0002] Existing communication satellite constellation systems, such as Iridium and Globalstar systems, satellites are located on different orbital planes to form a fixed constellation configuration, and the inter-satellite communication link is determined; while small satellite formation systems such as Techsat-21, TanDEM-X, GRACE, etc., also use a fixed formation configuration. These systems only establish a fixed inter-satellite communication link, and do not have inter-satellite data exchange and multi-hop transmission capabilities. They are not enough to be called inter-satellite networks, let alone self-organizing. network. The F6 system concept proposed by the United States, the system can operate autonomously, support module entry / exit, and...
