The current work is devoted to this problem, i.e., the autonomous orbit determination (AOD) between satellites locating around the DSs which are circling around the TLPs. Studies show that in order to obtain good AOD results, the data length should not be too short, and the satellite ...
The satellites in orbit of the BDS satellite navigation system are divided into three categories according to their orbit types. In this paper, the clock bias data of one satellite is taken as the test data for each type of satellite, and the satellite numbers are C01 (GEO Rb), C07 (IGSO...
3. Computing networks:Today’s networks provide content services like video and IoT and typically require 100-ms latency and a 30-fps frame rate, with most of the data downstream. In the world of the metaverse and digital twin, networks will mainly support applications like machine vision and ...

on November 19,2018 可知,本句要用一般过去时;send"发送"与句 子主语 Two new satellites of the BeiDou Navigation(导航) Satellite System(BDS)是被动关系,要用一般过去时的被动语态;且主语中 心词是复数名词 satellites,故谓语动词用复数形式。 2.safelyentered, safely"安全地"。 注意:safe变副词时直接加-...
The chip will be officially delivered by the end of this year and put into mass production in the first half of 2021, that can realize high-precision positioning in such fields as autonomous driving, drones and robots. Serving as the "brain" of a navigation device, the ...
