Installation Location of Car Navigation GPS Antenna?

Car navigation GPS antenna is installed under the upper cover panel of the center console. Below are detailed explanations about car navigation GPS: 1. GPS consists of three independent parts. Space segment: 21 operational satellites, 3 backup satellites. Ground support system: 1 master control station, 3 injection stations, 5 monitoring stations. User equipment segment: Receives signals transmitted by GPS satellites to obtain necessary navigation and positioning information, which is then processed to complete navigation and positioning tasks. 2. GPS receiver hardware is generally composed of a host, antenna, and power supply.
When installing a GPS antenna on my car, I found that the location really matters because the signal directly affects navigation accuracy. I usually choose the center of the roof, where there's less metal, providing the strongest signal. Once, I placed the antenna on the dashboard, but after applying heat-insulating film on the sunroof, the signal deteriorated, causing my navigation to freeze for a long time. Later, I moved it to a slightly elevated spot behind the rearview mirror, which worked well without obstructing the view. I recommend testing different locations before final installation: avoid all metal structures, such as A-pillars and roof rails. Additionally, metalized window films are hidden signal killers, so try to keep the antenna near the window. For regular car owners like me, it's good to periodically check if the antenna has shifted to avoid sudden malfunctions while driving, which can be frustrating. Remember, simple adjustments can significantly enhance your navigation experience.
I fell in love with DIY when I installed a GPS antenna on my car myself. Location is key—I chose the upper part of the front windshield near the window, where it's high enough and unobstructed, unlike placing it behind the glove box where signals easily drop. Installation is simple: the antenna has a magnet or adhesive on the back, just stick it on; but make sure it's not hidden under the roof beam, or satellite signal reception will be poor. Once, I placed it incorrectly near metal trim, causing constant navigation drift that made me go in circles; after adjusting to the right spot, accuracy improved dramatically. Pro tip: find an open area inside the car, like near the top of the dashboard, to easily avoid signal dead zones. DIYers like me can save on repair costs, but remember to clear any obstructions first.
