The nature of the GPS signal, explored below, means that GPS cable lengths should be kept as low loss as possible. The type of cable used as a GPS cable is critical to the performance of the cable assembly with specific types of coax that is manufactured to be low loss being preferable. They may also be required for connection of a Low Noise Amplifier (LNA) as explained below. Cables may be used to connect an external GPS antenna to a GPS device or an internal GPS antenna within a device.
This satellite navigation device has the software capabilities and drivers to extract the data from the satellite system and display it in an accessible format.Ī GPS cable is terminated with a class of radio frequency connector that is compatible with the antenna connector and capable of making a competent mechanical and electrical connection. Data received by the GPS antenna is transmitted down the cable to a GPS receiver.
The cable is, therefore, necessary for satellite communication between Space and User segments of GPS.
It is a critical component for utilizing the proprietary satellite radio navigation system that is created and owned by the United States Government and can be used to access the locating, navigation, and time functions of the system. Global Positioning System or GPS antenna cables are lengths of coaxial cable that are specifically used to conduct GPS signals from a GPS antenna to a downstream GPS radio receiver with minimal loss or change. Many GPS antennas have SMA-male connectors or antenna cables to SMA-male connectors:
