Abstract
With the development of the technique of di髓rential GPS,it develop a new domain for the using of GPS that attitude dete硼ination used by GPS carrier phase attitude detennination receivers have applied in many domains,such as land and can real
time navigation and attitude detemination this re鹬on,it off己r huge potential for
space application in reduce me cost of and some developed countries of
W色stem Europe were developing the incorpor“on of attitude determination、orbit detemination
and spacecraR independence navigation that usin2(; order to adapt the domestic demand
of attitude detennination,this paper does some work in attitude detemination by using GPS.
First,it introduced me development and application of GPS attitude detennination inside and outside of ,it introduced the basic theory of anitude detennination by use of carrier phase,established the models of attinlde paper discuss the main
error of attitude determination base on the attitude dete咖ination models,proposes a series of
technique a11d method to Danicular discuss the metllod of cycle slip detect and integer啪biguity resolution, proposes a new method f-or cycle slip detect and ambiguity resolution each base on panicular advantages t11at the length of baSeline is kno、Ⅵ1 nrSt and very
last,the method and the models that proposed before are verined by experimental data
and paper analysis the result 0f experimentations and discuss the reason of it.
Key words:GPS、a“itude determination、carrier phase measurement、cyclc slip、integer

第一章绪论
§ 引言
姿态测量是航空、航天、航海以及陆地导航系统的关键技术之一。目前传统的姿态测量系统主要有:光学和红外姿态测量或方位标定系统、惯性元件、航天上常用的各类星敏感器、太阳敏感器、地球敏感器等。
光学和红外仪器主要用于低动态和静态平台的监测,精度较高,但易受天气、。因此,对于动态测量而言,这两种手段没有什么意义。动态载体以往主要依赖于惯性导航系统(inertial navigation system, ins)和平台罗经等复杂的测量系统来提供载体的姿态信息。惯性导航系统
