When installing a GNSS antenna, components such as the coaxial cables and amplifiers should be selected to satisfy the antenna specifications of the GNSS receiver. It is also necessary to consider the propagation delay between the antenna and the receiver.
In this document, we explain how to calculate the required specification values with concrete examples from the viewpoint of a GNSS receiver manufacturers.
&#;Total gain
&#;Total NF
&#;Propagation delay in coaxial cables
It is especially useful for those who are new to GNSS receivers.
We have prepared an Excel tool for calculating "Total Gain" and "Total NF" due to their complex formulas.

GNSS and GPS modules are either transmitters that have antennas or receivers that do not, and they are both all-in-one modules that can be integrated into wireless devices with minimal effort. GNSS and GPS modules that come with an antenna use a LNA (low noise amplifier) and a SAW (surface acoustic wave) filter to help boost performance.
You will get efficient and thoughtful service from mide.
GNSS and GPS modules contain all the components, RF circuitry and antennas needed to connect to GPS and GNSS satellites. Modules receive timestamp data to ascertain the location of a device&#;all in an easy-to-integrate, compact format.
GNSS (Global Navigation Satellite System) describes the various satellite constellations used around the world such as GPS, GLONASS and Galileo. GNSS receivers use signals from multiple satellites in any of these constellations and use trilateration for pinpoint accuracy. GPS (Global Positioning System) refers to a specific type of GNSS which was developed in the s as the world&#;s first satellite constellation for navigation. GPS receivers use satellites that are from that specific constellation rather than others like with GNSS.
GNSS and GPS modules are used in navigation, positioning and timing applications such as personal navigation and asset tracking due to their precise locational properties. Through transmissions received from multiple satellites GNSS/GPS offers reliable reception in locations all over the world. Understanding how GNSS/GPS modules are integrated and perform is paramount to choosing the right module for specific applications.
