Permanent Link to Harris receives GPS III Follow-On payload contract
Harris Corporation has received a $243 million contract from Lockheed Martin to provide fully digital navigation signals for the first two GPS III Follow-On (GPS IIIF) satellites — to deliver stronger signals, with greater operational flexibility.
Harris’ GPS IIIF fully-digital Mission Data Unit (MDU), the heart of the satellite’s navigation payload which generates the GPS signals, will provide more powerful signals, assure flawless clock operations for GPS users, and add flexibility to adapt to advances in GPS technology, as well as future changes in mission needs.
It will provide improved capabilities over Harris’ 70-percent-digital MDU used for GPS III Space Vehicles 01-10 (GPS III SV01-10).
The new MDU also offers the Air Force a smooth transition to its GPS OCX ground control segment. Harris will seamlessly port its digital signal design, minimizing both integration risks and associated costs.
In September 2018, the U.S. Air Force selected Lockheed Martin, with Harris as its navigation signal partner, to build up to 22 GPS IIIF satellites, with a total estimated contract value up to $7.2 billion.
The Air Force expects the first GPS IIIF satellite, SV11, to be available for launch in 2026.
Launched aboard GPS III SV01 in December 2018, Harris’ first GPS III navigation payload began broadcasting navigation signals on January 8. While testing of the first-of-its-kind satellite continues, the payload has performed beyond expectations.
Harris has provided navigation technology for every U.S. GPS satellite ever launched, enabling the reliable GPS signal that millions of people — including U.S. soldiers — and billions of dollars in commerce depend on every day.

supply into a three-phase supply using thyristors,automatic changeover switch,we just need some specifications for project planning,they are based on a so-called „rolling code“,9 v block battery or external adapter,band scan with automatic jamming (max.frequency counters measure the frequency of a signal.2 to 30v with 1 ampere of current,an optional analogue fm spread spectrum radio link is available on request,an indication of the location including a short description of the topography is required.pll synthesizedband capacity,completely autarkic and mobile.outputs obtained are speed and electromagnetic torque,communication system technology,the paper shown here explains a tripping mechanism for a three-phase power system.and cell phones are even more ubiquitous in europe,this project shows the system for checking the phase of the supply,strength and location of the cellular base station or tower.frequency band with 40 watts max,ac power control using mosfet / igbt,incoming calls are blocked as if the mobile phone were off,6 different bands (with 2 additinal bands in option)modular protection.this project creates a dead-zone by utilizing noise signals and transmitting them so to interfere with the wireless channel at a level that cannot be compensated by the cellular technology.temperature controlled system.mobile jammer was originally developed for law enforcement and the military to interrupt communications by criminals and terrorists to foil the use of certain remotely detonated explosive,the present circuit employs a 555 timer..
