All in all, you found a point on the graph with known coordinates. Then start the GPS at hand, manually enter the coordinates of that point, and define a waypoint. Then start the GPS navigation fu...
1. You should conduct sufficient research on the area to be entered in advance. Now, the network is so developed that it is possible to study the target area using the electronic vector maps and s...
The GPS module generally supports two modes: cold start and hot start (Note: warm start warm-start is not discussed) Generally, the cold start time is much longer than the hot start time. Taking ...
About the track. Track is a track composed of discrete waypoints automatically recorded by GPS at regular intervals. GPS will intelligently record the points in the track to save space: when movin...

GPS receivers can receive time information accurate to nanoseconds that can be used for timing; forecast ephemeris used to predict the approximate position of satellites in the next few months; br...
In the late 1950s, the former Soviet Union launched the first man-made earth satellite. American scientists discovered the Doppler frequency shift phenomenon in their tracking research, and used t...
Mainly for positioning and navigation of moving objects such as ships, cars, and airplanes. E.g: 1. Ships ocean-going navigation and port diversion 2. Aircraft route guidance and approach and la...
First of all, the GPS system is a passive system for our users, that is, the user's receiver is only responsible for receiving, decoding, and computing, and will not return data, so as long as...
