7/20/2015 - ROBINS AIR FORCE BASE, Ga. -- For
the last 20 years, the world has experienced the unique capabilities of
a satellite precision navigation and timing system that has enhanced
the quality of our everyday lives. The technology's fast-tracking,
real-time capabilities, used by civilians as well as the military as
part of national and global security efforts.
This month we celebrate the 20th anniversary of the GPS, or global
positioning system -- July 17, 1995, when Air Force Space Command
declared full operational capability of the system.
During this time, a shop in the 567th Electronics Maintenance Squadron
here has been responsible for repairing and testing receivers used on
various weapon systems supported by the Air Force and Navy.
Bathed under bright lights and a maze of wires and work stations,
there's a shop in the 567th EMXS responsible for repairing and testing
several types of receivers used to communicate with GPS satellites.
John Fullington, a 402nd Electronics Maintenance Group electronics
technician, has been at Robins since 1989. He said he remembers the shop
getting its first assets in 1990, starting with prototypes.
"We've been going pretty strong ever since," he said.
He remembers the shop busily repairing receivers after the Sept.
11, 2001, terrorist attacks, and the workload is still active today. In
2014, nearly 500 units came through the shop.
Technicians use one of several test stations to test individual circuit
cards located inside a receiver. Among several receivers tested by one
of the shop's seven technicians is the 12-channel 3A SAASM receiver,
which has been modified over the years to use less circuit card space,
making it lighter and more efficient.
There's also JPADS, or the Joint Precision Airdrop System, which is used
to direct equipment to the ground once it's deployed from an aircraft.
According to AFSPC, today's Airmen conduct resupply missions with
battlefield precision airdrops to combat forces with GPS-guided
parachute-delivered equipment pallets; and during Operations Enduring
Freedom and Iraqi Freedom, significant contributions were made,
including the delivery of 5,500 GPS-guided Joint Direct Attack Munitions
with pinpoint precision.
Glenn Collins, an electronics mechanic at Robins for 33 years, has
worked in the shop since its inception. He operates a 'hot mock-up'
station where satellite signals are searched in real-time to make sure
receivers are working properly.
"We can now see which satellites are available," he said. "I've enjoyed
many years getting things out back to the warfighter. I'm proud to have
been a part of this."
The station's configuration was fabricated in the shop years ago and is
still used today. Within about 15 minutes, Collins can get a quick fix
on which satellites are in view at the moment, giving him a good read on
whether information that's been downloaded on a receiver works or not.
Whether GPS guides stormtrackers to accurately forecast the next big
storm or successfully leads troops out of harm's way, there's little
doubt its benefits have impacted the world and will continue for many
