澳大利亚新南威尔士大学开发出能接收来自全球定位系统(GPS)和伽利略两个卫星系统多个频率信号的接收器。
In recent years, with the development of satellite orbit and clock parameters accurately determining technology and the popularity of geodetic GPS receivers, Common-View (CV) which proposed in 1980 by...
日本版GPS蓄势待发     日本版  GPS  定位卫星  卫星系统       2017/5/19
卫星定位是物联网、大数据等相关产业的基础,各国竞相竞争。同时,其在宇宙开发应用中也处于先导地位。日本版GPS正在加紧实施,日本内阁府最近公开了准天顶卫星系统“引路”第2号定位卫星。日本计划2017年秋天,用国产火箭“H2A”发射2号机等三颗定位卫星,加上以前发射运行的1号机,从2018年度开始将共有四颗定位卫星运行。离正式运行仅剩1年的日本版GPS试图超越美国及欧洲,开创日本自主的新业态。
GPS Pseudolite Signal Design     GPS  Pseudolite  Signal Design       2015/6/29
Pseudolites (PLs), ground-based satellites transmitting GPS-like signals, are becoming increasingly useful for a variety of applications, including differential GPS correction broadcasting and aircraf...
The Integrity Beacon Landing System (IBLS), developed and tested at Stanford Universi GPS-based Category III precision landing. IBLS is a Kinematic GPS system which iIntegrity Beacon pseudolites place...
This paper describes the most recent advances in our research on GPS(global positioning system) for real-time structural motion sensing and control. The goal of this work is to bring to light the impo...
There are an increasing number of applications requiring precise relative position and clock offset information.The Global Positioning System has demonstrated precise and drift free position and timin...
This paper presents a GPS receiver satellite/antenna selection algorithm for the Stanford Gravity Probe B Relativity Mission.
One of the difficulties inherent in use of Global Naviga tion Satellite Systems (GNSS) for safety-critical applica tions is the need to insure user integrity in the face of an unbounded array of...
The low latitude ionosphere poses a challenge to both GPS users and Satellite-Based Augmentation System(SBAS) providers. Single and dual frequency GPS receivers used in low-latitude regions can suffer...
This paper describes the collection and analysis of real data from twenty-four current, nominally healthy GPS satellites in the context of the ICAO second-order step (2OS) fault model.
In anticipation of the future launches of dual-frequency GNSS satellites, such as Galileo and GPS block III, a series of new developments has taken place in the field of Receiver Autonomous Integrity ...
The local area augmentation system (LAAS) is a differential GPS navigation system being developed to support aircraft precision approach and landing navigation with guaranteed integrity and availabili...
For the Global Positioning System (GPS), real-time satel-lite orbits and clock biases are derived from predicted ephemeris and clock parameters in broadcast navigation messages. The performance of bro...
暗物质影响着星系的形成,无处不在却难以捉摸。最近,美国和加拿大物理学家提出,为我们提供城市导航的GPS(全球定位系统)设备有可能成为直接探测和测量暗物质的强大工具。研究小组在今年召开的科学会议上提出了这一理论,被科学团体广为接受,相关论文提前在线发表于2014年11月17日的《自然·物理学》杂志上。
