Time and Frequency Measurements Using the Global Positioning System
GPS, well known as a versatile, global tool for positioning, has also become the primary system for distributing time and frequency. GPS receivers are fixtures in telecommunication networks, and calibration and testing laboratories. They make it possible to synchronize clocks and calibrate and control oscillators in any facility that can place an antenna outdoors for lineof-sight reception of t...
متن کاملReal-Time Navigation Using the Global Positioning System
For more than a decade, TRW has been involved in aerospace applications of the Global Positioning System (GPS). TRW Ballistic Missiles Division first began working with GPS on a Minuteman missile test flight program in 1980. Since then, TRW has applied GPS to programs such as the Peacekeeper missile, the F-22 fighter aircraft, the Orbital Maneuvering Vehicle, Brilliant Pebbles, and classified s...
متن کاملAutomated time study of skidders using global positioning system data
Time study is an important research tool used in comparing productivity of forest harvesting systems across varying conditions. Unfortunately, it has been an expensive tool to apply, involving travel and fieldwork by a crew of technicians plus time in the office to reduce raw data to usable information. In the interests of safety and cost reduction, it would be preferable to have a means of per...
متن کاملAttitude Determination Using Global Positioning System Signals
In this paper, a novel technique for finding a pointby-point (deterministic) attitude solution of a vehicle using Global Positioning System phase difference measurements is presented. This technique transforms a general cost function into a more numerically efficient form by determining three-dimensional vectors in either the body or reference coordinate system. Covariance relationships for the...
متن کاملCompensation of Doppler Effect in Direct Acquisition of Global Positioning System using Segmented Zero Padding
Because of the very high chip rate of global positioning system (GPS), P-code acquisition at GPS receiver will be challenging. A variety of methods for increasing the probability of detection and reducing the average time of acquisition have been provided, among which the method of Zero Padding (ZP) is the most essential and the most widely used. The method using the Fast Fourier Transform (FFT...
