GPS Basics
Generally a GPS receiver gives out a precise 1 PPS pulse (1 pulse per second) to mark exact second intervals (1 s). This signal is used for precise timing and synchronization
GPS Tutorial
GPS is a complex technology but understanding it can be quite easy if you take it one step at a time. This tutorial is designed to give you a good basic understanding of the principles behind GPS without loading you down with too much technical detail.

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.

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.
