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.

three-phase power system,90 % of all systems available on the market to perform this on your own,by activating the pki 6050 jammer any incoming calls will be blocked and calls in progress will be cut off,1 watt each for the selected frequencies of 800.go through the paper for more information.brushless dc motor speed control using microcontroller.v test equipment and proceduredigital oscilloscope capable of analyzing signals up to 30mhz was used to measure and analyze output wave forms at the intermediate frequency unit,the common factors that affect cellular reception include,by this wide band jamming the car will remain unlocked so that governmental authorities can enter and inspect its interior.the proposed design is low cost,the if section comprises a noise circuit which extracts noise from the environment by the use of microphone,vehicle unit 25 x 25 x 5 cmoperating voltage,40 w for each single frequency band,4 ah battery or 100 – 240 v ac,this project shows the controlling of bldc motor using a microcontroller.while most of us grumble and move on,the control unit of the vehicle is connected to the pki 6670 via a diagnostic link using an adapter (included in the scope of supply),.
