Detailed explanation of GPS NMEA-0183 Protocol NMEA AssociationThe purpose of this discussion is to establish a unified btcm (maritime radio technology commission) standard in different GPS (GPS) navigation devices by the National Oceanic Electronics Association (

NMEA is a set of standard information that defines the output of the receiver. There are several different formats, each of which is an independent ASCII format that separates data streams. The data stream length ranges from 30 to characters, the output is usually selected at intervals per second. The most commonly used format is "GGA". It contains the positioning time, latitude, longitude, height, number of satellites used for positioning, and other

Introduction to the GPS software of G1 and how to enable the GPS module We still use G1 as an example. G1 is equipped with a hardware GPS chip. However, most of the available GPS maps in G1 currently do not support offline image libraries, that is to say, you must ens

and is also the result of filtering in the channel. When moving compensation is used to calculate the sample set, the average effect makes the satellite equal to the point in the moving path corresponding to the sample time. This simplified processing is available for low-Position Precision and receiver movement speed, and is especially applicable for High-Position Precision and fast movement, then, the related computation is performed based on the collection time of the sample set. For higher

Test the u-box GPS professional testing software u-center map function Some time ago, I mailed a GPS module from the Internet and recently played GPS positioning. I found a Go-GPS module that can call GoogleEarth, and the coordinates are displayed in real time, but I have n

Milugps is a simple GPS software for your mobile phone. This software can run on wm5.. Net CF 2.0 platform, which can be connected to a GPS receiver (such as a Bluetooth GPS receiver) connected in the form of a serial port. maps can be converted from Ozi using map spaces.
