GALILEO
Galileo will be Europe’s own global satellite navigation system, providing a highly accurate, guaranteed global positioning service under civilian control. It will be inter-operable with GPS and GLONASS, the two other global satellite navigation systems. This means that a user will be able to take a position with the same receiver from any of the satellites in any system
 

Global Positioning System (GPS)
A highly accurate, global satellite navigation system based on a constellation of 24 satellites orbiting the earth at a very high altitude. In addition to navigation, the system also provides very precise time
 

GLONASS
GLONASS (GLObal NAvigation Satellite System) is a satellite based radionavigation system which enables unlimited number of users to make all-weather 3D positioning, velocity measuring and timing anywhere in the world or near-Earth space
 

GMT Greenwich Mean Time
A 24 Hour system based on mean solar time plus 12 hours at Greenwich, England. Greenwich Mean Time can be considered approximately equivalent to Coordinated Universal Time (UTC), which is broadcast from all standard time and frequency radio stations. However, GMT is now obsolete and has been replaced by UTC
 

GPS
Global Positioning System
 

GPS Pcode
This is called the precise code or "protected code" and is a series of pseudorandom, binary byphase modulations on the carrier and has a chip rate of 10.23 MHz. The P code repeats about every 267 days. Each 1 week segment of the code is unique to a particular GPS satellite and is reset each week
 

GPS signals
GPS signals {broadcast signals of GPS and their functions are as follows}:
• L1 - 1575.42 MHz
- C/A and P codes and navigation data
• L2 - 1227.6 MHz
• L3 - 1381.05 MHz

GPS C/A code The standard GPS code known as the coarse/acquisition code or "civilian code." The code is a series of 1023 pseudorandom binary byphase modulations on the carrier and has a chip rate (bit transition time) of 1.023 MHz (often called "Standard Positioning Service
