    This paper describes the development of a low-cost and small size integrated Global Positioning System (GPS)/inertial measurement unit (IMU). The developed strapdown Attitude and Heading Reference System (AHRS) is capable of providing attitude and heading accuracy at ±0.2 and ±0.4 degrees, respectively. The prototype of low-cost integrated GPS/IMU can give positioning accuracy of 10 ... View full abstract»

    The FAA's Flight 2000 project is an innovative initiative to implement and validate selected operational improvements leading to Free Flight. It integrates new avionics, new ground systems, new procedures, avionics certification, and operational approval. Approximately 2000 aircraft operating in Alaska, Hawaii, and Oceanic airspace will be equipped with new capabilities enabling benefits such as i... View full abstract»

    Multipath interference limits the speed and accuracy of determining position by “differential” GPS techniques. A geodetic surveyor, for example, requires multipath interference rejection of about 36+20 log10 sin ε dB, where ε is the elevation angle of the satellite being observed. Signal processing in a GPS receiver cannot satisfy this requirement. A receiving ante... View full abstract»

    In this paper, the design plan of the tracking system of the telemetering antenna in a type of pilotless aircraft is introduced. The discussion centres on the controls. Then the format of control words and an algorithm, which are effectively used to control the stepping motor are given. This algorithm has a function of parallel control and has already been used in our research. The design of the a... View full abstract»

  • Relative navigation for multi-spacecraft system with GPS

    Publication Year: 1998, Page(s):25 - 28
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (260 KB)

    A type of multi-spacecraft system with kinematical restraint but no structural restraint and force action is considered. Both the absolute and relative navigation information is required for this multi-spacecraft system, but the relative information is more critical and the accuracy requirements for relative information will be much higher than those for the absolute information. In this paper, th... View full abstract»

    For proficiently operating an unmanned aircraft, the aircrew must be thoroughly trained. However, using practical equipment to train the aircrew is work of high cost and risk. In this paper, a system of simulation training for unmanned aircraft is introduced. Its function and composition are explained in detail. In practice, the system not only decreases training cost and risk, but also strengthen... View full abstract»

    A wide variety of applications can benefit from integrated Inertial Navigation System/Global Positioning System (INS/GPS) technology. However, in many situations, the end user has a preference for a specific GPS receiver. Additionally, in most cases, the user does not desire to expend the time and money necessary to perform a custom INS/GPS integration, but instead wants a low-cost off-the-shelf s...
