How to Clean GPS Antenna. we can remove GPS Antenna Oxidation to improve GPS signal. for example if we install an permanent mounted GPS antenna on boat, the male connector from the antenna oxidizes over time and the connection to the unit, sometimes, does not conduct the antenna info. so a can of brake and electrical contact cleaner will work wonders. you can pick one up for about 6 bucks at your local auto parts store. spray it on and let it sit for a couple minutes then …

New GPS Receiver Initialization. When your GPS unit is turned on for the first time, it does not know where it is, the date or the time. To initialize a GPS unit is to basically tell the receiver where it is, what the date is, and what the time is. This allows it to know which satellites should be overhead, so it can start searching for them to lock onto them. When a new GPS receiver is first powered-up, even if it is not initialized, it can still determine its …

GPS no signal or it take GPS time to find a signal, these are two major problems when we use GPS device. Many factors will affect GPS receivers to receive satellite signals. some barriers or parking deck will interrupt GPS to start receiving a signal. like:
Method (code) to identify each satellite.
The location of the satellite or some information on how to determine it.
Information regarding the amount of time elapsed since the signal left the satellite.
Details on the satellite clock status, etc.
Most GPS receivers allow you to set up a margin …

how to save waypoints in GPS receiver memory. A waypoint is a position you wish to save and return to later. GPS receivers typically offer two methods to store waypoints in memory: 1. The Quick Save method, which uses the coordinates from either your present position, or those from the cursor position in the plotter mode. In this method, the waypoint is automatically identified with the next available waypoint number in the list; 2. The View & Save method, which lets you pick the specific waypoint number under which you …

GPS chipset comparison:the GPS receivers accuracy mostly depend on GPS chips. it determine how to receive satellite singals. the GPS chips just like compter CPU. the most popular GPS CHIP is Sirf III (the third-generation chip, With 20 satellite channel. the sirf II with 12 satellite channels). There are other chips like sony CHIP and Switzerland RFMD chip. But the SIRF chips work better.
