The Difference Between Iridium and GPS Antenna

Time of issue:

2025-11-12

The application of Iridium antennas and GPS antennas is crucial in outdoor communication, navigation, aviation, and the Internet of Things.In simple terms, they are two types of antennas with completely different functions, distinct working principles, and entirely separate design goals.Comparing them to "Pipes" and "Water Meters" might not be the most appropriate, but it can be understood as the difference between "Walkie-Talkies" and "Radios".

 

Characteristic

Iridium Antenna

GPS Antenna

Main Function

Bidirectional reception

(Sending and receiving signals)

Unidirectional reception

(Only receives signals)

Design

Requirements

It is necessary to strike a balance between transmission and reception performance, and be able to withstand high power during transmission.

Focused on optimizing signal reception quality, with no requirements for transmission performance.

Type

Passive

Active

Technical Core

High efficiency, high power tolerance, low elevation angle performance

High sensitivity, resistance to multipath interference

Frequency Range

Broadband

(Reception: 1616-1626.5MHz;

Transmission:1616-1626.5MHz)

Single frequency point or narrow band

(For example: L1: 1575.42MHz)

System

Iridiu System composed of 66 low orbit satellites)

GPS(USA)、Bedou(China)、GLONASS(Russia)、Galileo(European Union) etc.

Core Requirements

High gain, low loss,

capable of effective transmission and reception

High sensitivity, relative stability,

Resistance to multipath interference

Polarization

Linear polarization usually

Right-handed circular polarization(RHCP) usually

Application

Maritime satellite phone, field exploration emergency communication, aviation data link, military communication

Asian Creation's small-sized 5G omnidirectional antenna successfully completed on-site wireless networking testing

The miniaturized 5G omnidirectional fiberglass antenna developed by Asian Creation Company for complex scenarios has recently successfully completed on-site wireless networking testing, breaking through industry pain points in a "short and concise" form and injecting new momentum into the landing of 5G applications. This antenna breaks through traditional volume limitations and uses fiberglass material to create a streamlined appearance, ensuring signal transmission stability while also considering aesthetics and portability. Through integrated structural design, it can seamlessly integrate with customer equipment modules, greatly reducing deployment complexity - whether it is a small data center, mobile emergency vehicles, or space sensitive industrial scenarios, it can be easily adapted. The "ready to use" feature makes 5G coverage more flexible. In field testing, the antenna has accurately overcome industry challenges such as "signal attenuation in narrow spaces" and "interference in special environments" while maintaining the core advantages of 5G high speed and low latency Aiming at "signal blind spots" such as indoor dense partitions and underground pipe galleries, the omnidirectional radiation characteristics achieve 360 ° coverage without blind spots, and the signal strength is increased by more than 30%; Faced with special working conditions such as high temperature, high humidity, and strong electromagnetic interference, the weather resistance and anti-interference ability of the fiberglass shell ensure stable links, and the packet loss rate is controlled within 0.1%. In the future, this antenna will be widely used in fields such as smart factories, emergency rescue, and vehicle communication. With a more compact form and reliable performance, it will promote the advancement of 5G from "wide coverage" to "deep coverage", allowing high-speed networks to truly penetrate every segmented scenario.
