GPS L1 1575.42MHz Active Adhesive Antenna, Certification : CE Certified, ISI Certified, ISO 9001:2008

It sounds like you're referring to a specific type of GPS antenna. Here's a breakdown of what each part of the description means:

• GPS L1: This refers to the primary frequency used by the Global Positioning System (GPS) for civilian navigation. The L1 frequency is 1575.42 MHz.

• 1575.42 MHz: This is the exact frequency of the L1 signal. It's used for receiving GPS signals from satellites.

• Active: This indicates that the antenna has an integrated amplifier to boost the signal strength. Active antennas are often used in applications where the signal might be weak or where greater precision is needed.

• Adhesive: This suggests that the antenna can be attached to surfaces using an adhesive backing. This is useful for mounting the antenna in places where drilling or permanent mounting might not be practical.

• Antenna: This is the device used to receive GPS signals.

An active adhesive GPS antenna with these specifications would be suitable for various applications where you need a reliable GPS signal and where you can easily attach the antenna to a surface. It's often used in automotive GPS systems, navigation devices, and other applications requiring accurate location data.
