Introduction to the Global Positioning System for GIS and TRAVERSE
The Global Positioning System (GPS) is a location system based on a constellation of about 24 satellites orbiting the earth at altitudes of approximately 11,000 miles. GPS was developed by the United States Department of Defense (DOD), for its tremendous application as a military locating utility. The DOD's investment in GPS is immense. Billions and billions of dollars have been invested in creating this technology for military uses. However, over the past several years, GPS has proven to be a useful tool in non-military mapping applications as well.
GLOBAL POSITIONING SYSTEM STANDARD POSITIONING SERVICE SIGNAL SPECIFICATION (PDF 51P)
The GPS SPS Signal Specification defines the service to be provided by GPS to the civil community.
Introduction, definition of terms, Qamp;As
In the operation of electronic systems and circuits, the basic function of a filter is to selectively pass, by frequency, desired signals and to suppress undesired signals. The amount of insertion loss and phase shift encountered by a signal passing through the filter is a function of the filter design.
Coupler Theoretical Main Line Loss Calculation
The main-line loss of a coupler is defined as the loss between the input and output ports. Theoretical loss is defined as that of a perfect (lossless)coupler, for which the input power is the sum of the (main-line) output power and the power at the coupled port.
Do it yourself couplers reduce cost
Ever expanding applications of RF and Microwaves for Wireless and Cable applications have revived the development efforts of components at these frequencies.
SM Quadrature Couplers have high performance, low cost
A series of high performance 3 dB quadrature couplers has been developed using Blue Cell� technology.
