Abstract

The invention discloses a cooperative localization-based terminal-to-terminal orientation method. The cooperative localization-based terminal-to-terminal orientation method is characterized in that wireless ranging and pseudo range double difference orientation methods are used in combination. The cooperative localization-based terminal-to-terminal orientation method comprises the following steps that: a terminal acquires satellite observation data of a global navigation system so as to obtain satellite pseudo range information; a pseudo range difference model is established through utilizing satellite observation values of the global navigation system and navigation satellite observation values of adjacent terminals; terminal-to-terminal distances which are measured through the pseudo range double difference and wireless ranging methods are combined together, so that a terminal-to-terminal orientation equation is established; and orientation results can be obtained through adopting different orientation methods under the situation that common visible satellites are different in quantity, and terminal-to-terminal orientation can be realized when common visible satellites are fewer than four. The invention also discloses a terminal-to-terminal orientation device. With the cooperative localization-based terminal-to-terminal orientation method and the device adopted, terminal-to-terminal orientation when common visible satellites are fewer than four can be realized, and therefore, the cooperative localization-based terminal-to-terminal orientation method and device of the invention have high practical values.
