Trimble ThunderBolt Timing GPS Receiver GPSDO 10MHz 1PPS GPS Disciplined Clock

Description

Trimble ThunderBolt Timing GPS Receiver GPSDO
Trimble has been making GPS receivers since the system has been in existence.   They made the Trimpack which was one of the first GPS units used in Desert Storm.  The U.S. then used the PLGR GPS receiver and now (2008) the DAGR.  But these GPS receivers were intended for use mainly as navigation tools and only supported timing in the sense of frequency hopping radios like SINCGARS.  The Motorola GPS receivers have had a precision time capability and the M12T+ is very good at that (Motorola has sold the GPS receiver operation and it's now part of i-LOTUS and is sold by Synergy.
There are two first generation Trimble Thunderbolt GPS receiver versions.
p/n 48050-61 for the metal cage 24 Volt
p/n 48051-61 for the board only that needs +5, +12 & -12 Volts
The board only in a metal box that needs +5, +12 & -12 Volts may have been a custom part.
The first generation ThunderBolt receivers went out of production in mid 2006 because of Rohas lead free EU rules.
The Thunderbolt is what's called a GPS Disciplined Oscillator (GPSDO).  The internal 10 MHz oscillator has it's tuning voltage controlled by the GPS time.  The 10 MHz is divided down to provide a 1 Pulse Per Second (!PPS) output.  If the GPS signal is lost it goes into holdover mode.
This is huge improvement over the old lab crystal oscillators that needed to be manually tweaked (calibrated) every 6 to 12 months to account for crystal aging.  With the GPSDO the corrections are applied automatically in real time as long as you have GPS reception.   A GPSDO is an excellent way to have a lab frequency standard to drive test equipment that accepts external 10 MHz references signals like counters, spectrum analyzers etc.  The 1PPS signal is a good way to make precision time interval measurements.
