Autonomous formation flyer technology developed by jpl is used three receiving antennas and one transmitting antenna are installed on each satellite each of satellites can transmit analog gps signal but more accuracy. the multiple receiving antennas on the every satellite are capable of acquiring precise pesudorange and carrier phase signals transmitted by other satellite and compose of a kind of onboard augment gps system
在文中，利用jpl提出的自主編隊飛行技術aff ，在每個編隊衛星上安裝一個發射天線和三個接收天線，每一個發射天線可以發射類似於gps的高精度偽距和載波信號，與其它衛星上的多個接收天線構成星載擴展gps系統。 -
Economic globalization is the most basic character of current worldwide economic development and it greatly changes the economy, politics ， culture and social lifestyle in every country after china ' s entry into wto ， it will take more active part in the process of the economic globalization both in wider fields and in deeper degree to the ideological and political education ， economic globalization is a sword with both sharp sides ， that is ， on one hand ， it provides great opportunities for the development of the current ideological and political education ， and on the other hand ， it also brings austere challenges therefore ， on the basic of the era features and the changes in our thoughts we must ke 印 pace with the times and build up new creative education system ， suitable for the economic globalization ， for the ideological and political education in order to propel powerfully the full development of our country and human beings there are three main parts in this essay the first part mainly discusses the meaning and characters of economic globalization to deepen people ' s knowledge about economic globalization and the second illustrates the opportunities and challenges confronted by the ideological and political education caused by the economic globalization ， so that the great importance and necessity of enforcement and improvement in the ideological and political education can be realized the last part states the innovation of ideological and political education under the background of economic globalization ， focused on the analysis of five points ： notion innovation ， content innovation ， m ~ hod innovation ， carrier innovation and mechanism innovation
經濟全球化對於思想政治教育來說，是一柄兩刃劍，既給新時期的思想政治教育提供了發展的機遇，同時又帶來了嚴峻的挑戰。因此，我們必須根據時代的特點和人們的思想變化，與時俱進，建立與經濟全球化相適應的思想政治教育創新體系，使思想政治教育更加有力地推動社會發展和人的全面發展。本文主要包括三個部分內容：第一部分介紹了經濟全球化的基本情況，加深人們對經濟全球化的認識；第二部分闡述了經濟全球化給我國思想政治教育帶來的機遇和挑戰，使人們認識到加強和改進思想政治教育的必要性和重要性；第三部分論述了經濟全球化背景下的思想政治教育的創新，著重從觀念創新、內容創新、方法創新、載體創新、機制創新五個方面進行分析。 -
The system can generate three - phase spwm pulses and has following characters : the range of modulation frequency is from 0 khz to 4 khz. and can be divided to 7 classes to control. the carrier frequency may be selected up to 24 khz, and can be divided to 8 classes to control ; rotational frequency is defined to 16 bits
該系統能產生三相六路正弦脈寬調制（ spwm ）波形;調制頻率范圍為0 4khz ，分7級控制; 16位的速度控制解析度;載波頻率分8級控制，最高可達24khz ;系統介面兼容intel系列和motorola系列單片機;該系統控制簡單、精確，易修改，可現場編程;同時具有脈沖延時小、最小脈沖刪除、過壓和過流保護功能等特點，可應用於pwm變頻調速系統的全數字化控制。
