## **1. Introduction** 

The GGSFTP.50.7.A.08 is a 50*50mm terrablast GPS/GLONASS/GALILEO with GPS L2 low profile, embedded stacked passive patch antenna with 7mm thickness. The antenna has been tuned and tested on a 70*70mm ground plane, working at GPS 1575.42MHz, 1227.6MHz and GLONASS 1602MHz, with 4.3dBi gain, 2.6dBi gain and 4.6dBi gain, respectively. 

The low-profile patch design also utilizes the Taoglas Terrablast material which provides a lightweight and robust solution for applications which require high impact resistance such as drones, ATVs and vehicles and is the ideal embedded solution for applications such as: 

 Precision Transportation 

- Tracking and Inventory Management 

Defense 

Marine 

Aviation 

 Agriculture 

 UAV Navigation 

 Surveying 

- Improved Weather forecasting 

The GGSFTP.50.7.A.08 builds on the success of the groundbreaking series of high precision antennas by Taoglas and is an addition to the ongoing product roadmap. This antenna works well without modifications in most environment but can be tuned and further optimized to different ground planes and enclosures if this is required. Custom antenna modifications are subject to possible NRE and minimum order quantity. 

Terrablast antennas are not suitable for SMD reflow. The correct method is manual soldering at a soldering temperature of 380°C +/- 20°C for a duration of 3 to 5 seconds. All Terrablast antennas undergo rigorous temperature, vibration and impact
