Frequently Asked Question
Do you have any question?
While the terms are often used interchangeably, GNSS (Global Navigation Satellite System) is the broader category. GPS is the specific system operated by the United States. A modern GPS antenna is almost always a GNSS antenna, meaning it can receive signals from multiple constellations like GPS, Beidou, GLONASS, and Galileo for improved accuracy and reliability.
An external GPS antenna is necessary when the main device or receiver is located inside a metal enclosure, a vehicle cabin, or a building where it cannot get a clear view of the sky. An external antenna can be mounted in a location with optimal signal reception (like a vehicle's roof) and feed the clean signal to the receiver via a cable.
An active GPS antenna has a built-in low-noise amplifier (LNA) that boosts the satellite signal before sending it down the cable to the receiver. This is crucial for overcoming signal loss in long cable runs and is the standard for almost all modern vehicle and telematics applications. A passive antenna has no internal amplification.
The mounting location is critical. For the best performance, a GPS antenna must have a clear, 360-degree view of the sky. It should be mounted as far as possible from other antennas and sources of electronic noise to prevent interference and signal blockage, ensuring it can track the maximum number of satellites.
These refer to the different frequencies on which GPS satellites transmit. A standard consumer GPS antenna typically only receives the L1 band. A high-precision, multi-band antenna can receive L1, L2, and L5 signals, which allows the receiver to correct for atmospheric errors and achieve centimeter-level accuracy for applications like surveying and autonomous driving.
Not necessarily. You must ensure compatibility. The most important factors are the voltage requirement for an active GPS antenna (typically 3V or 5V) and the connector type (e.g., SMA, FAKRA). Using an antenna with the wrong voltage or connector can lead to poor performance or even damage the components.
