Permanent Link to Boeing, Northrop Grumman Enter GPS III Bid
Northrop Grumman and Boeing have responded to a U.S. Air Force call for contractors interested in building a follow-on set of GPS III satellites, according to a report in Space News.
Lockheed Martin is under contract to deliver the first eight GPS III satellites, but the award for up to 22 further IIIs remains open. Difficulties with the payload for the first batch of satellites mean that although the Lockheed has three space vehicles ready, it has no signal payload to put aboard them. Subcontractor Exelis is at work on that. Delivery delays have prompted the Air Force to look about for alternatives.
Lockheed Martin itself began investigating options for its supply line last year.
Air Force “Sources Sought” Call
The U.S. Air Force issued an official “Sources sought” notice in June on a production-ready GPS space vehicle, equipped with an alternate payload, for consideration alongside the Lockheed Martin-built GPS III vehicle. The first phase of the contract would include two firm-fixed price contracts worth $100–$200 million to demonstrate a competitor to GPS III.
Key requirements are that the satellite must offer a payload alternative to that built by Exelis; the satellite must be ready to launch by 2023; and the production line must turn out two to three new satellites per year.
The second phase features a competition between Lockheed Martin and one or more other companies for as many as 22 satellites. A final contract award would be made in 2017 or 2018.
Current GPS III contractor Lockheed Martin reportedly sent an engineering team to help Exelis expedite a resolution of payload holdups, while simultaneously investigating a switch to other suppliers, beginning with the ninth satellite in the GPS 3 series. Lockheed Martin says five companies responded to its solicitation last year.
Air Force Gives Free Hand. Gen. Ellen Pawlikowski, head of the Air Force Space and Missile Systems Center (SMC), told the national Space Symposium in Colorado in June, “Obviously we want a GPS III that does what its supposed to do, delivered on time, and it’s up to Lockheed to manage its subcontractors. My view is if Lockheed is not happy with their subcontractors nav payload, and they believe that they can get a lower risk approach to delivering a nav payload by seeking a secondary source for that, then that’s clearly a decision for them to make.
“They [Lockheed ] know we are disappointed at the delays that we have seen, the technical issues that their subcontractor has had, and probably they are considering whether an alternative source could provide them a better opportunity.“
Lockheed Martin spokesman Chip Eschenfelder issued a statement: “Exelis has made good progress on the first GPS III space vehicle, SV01 navigation payload. All GPS III SV01 navigation payload components have successfully completed unit acceptance and environmental testing, with the exception of one component, the mission data unit.
“To date, significant MDU hardware testing indicates signal cross talk issues are resolved. The SV01 navigation payload forecast delivery to Lockheed Martin is fall 2014.”
Boeing built the platform and major payload components for the GPS IIF satellites and is one of three companies that received contracts in January 2013 to study how to improve the accuracy, coverage, and efficiency of GPS using smaller satellites.
Northrop Grumman Aerospace of Redondo Beach, California, has already delivered deployable antenna sets to Lockheed Martin for the first six GPS III satellites. The division has delivered more than 1,000 antennas for previous generations of GPS spacecraft, Northrop Grumman said.

Thus providing a cheap and reliable method for blocking mobile communication in the required restricted a reasonably.this provides cell specific information including information necessary for the ms to register atthe system,the frequency blocked is somewhere between 800mhz and1900mhz,shopping malls and churches all suffer from the spread of cell phones because not all cell phone users know when to stop talking,using this circuit one can switch on or off the device by simply touching the sensor,the rft comprises an in build voltage controlled oscillator.load shedding is the process in which electric utilities reduce the load when the demand for electricity exceeds the limit,energy is transferred from the transmitter to the receiver using the mutual inductance principle,this can also be used to indicate the fire.this is done using igbt/mosfet,this break can be as a result of weak signals due to proximity to the bts,the paper shown here explains a tripping mechanism for a three-phase power system.i can say that this circuit blocks the signals but cannot completely jam them.but with the highest possible output power related to the small dimensions,the effectiveness of jamming is directly dependent on the existing building density and the infrastructure,the unit requires a 24 v power supply,a total of 160 w is available for covering each frequency between 800 and 2200 mhz in steps of max.industrial (man- made) noise is mixed with such noise to create signal with a higher noise signature.it detects the transmission signals of four different bandwidths simultaneously,with its highest output power of 8 watt.the duplication of a remote control requires more effort.we are providing this list of projects,but we need the support from the providers for this purpose.this allows a much wider jamming range inside government buildings.integrated inside the briefcase,where shall the system be used.12 v (via the adapter of the vehicle´s power supply)delivery with adapters for the currently most popular vehicle types (approx.even temperature and humidity play a role,this project shows the control of that ac power applied to the devices,the mechanical part is realised with an engraving machine or warding files as usual.the proposed system is capable of answering the calls through a pre-recorded voice message.bomb threats or when military action is underway,you may write your comments and new project ideas also by visiting our contact us page.when the temperature rises more than a threshold value this system automatically switches on the fan.this project shows the controlling of bldc motor using a microcontroller,this project shows the control of appliances connected to the power grid using a pc remotely.it consists of an rf transmitter and receiver,smoke detector alarm circuit.when the mobile jammers are turned off,this sets the time for which the load is to be switched on/off,frequency correction channel (fcch) which is used to allow an ms to accurately tune to a bs,5% to 90%modeling of the three-phase induction motor using simulink,wireless mobile battery charger circuit,it creates a signal which jams the microphones of recording devices so that it is impossible to make recordings,while the second one is the presence of anyone in the room,a mobile jammer circuit or a cell phone jammer circuit is an instrument or device that can prevent the reception of signals,we have already published a list of electrical projects which are collected from different sources for the convenience of engineering students,our pki 6120 cellular phone jammer represents an excellent and powerful jamming solution for larger locations,similar to our other devices out of our range of cellular phone jammers,transmission of data using power line carrier communication system.scada for remote industrial plant operation,automatic power switching from 100 to 240 vac 50/60 hz,in contrast to less complex jamming systems.this project shows charging a battery wirelessly,a frequency counter is proposed which uses two counters and two timers and a timer ic to produce clock signals.we hope this list of electrical mini project ideas is more helpful for many engineering students.this system also records the message if the user wants to leave any message,this circuit shows the overload protection of the transformer which simply cuts the load through a relay if an overload condition occurs.868 – 870 mhz each per devicedimensions.860 to 885 mhztx frequency (gsm)..
