PRN 17, the first IIR-M satellite launched in September 2005, began broadcasting the second GPS civil signal, L2C, in December 2005. PRN 17 is the first in the new generation of GPS satellites with a new feature called flex power. According to the U.S. Air Force, flex power adds the capability for the Department of Defense to increase power on both P- and M-code (both military) signals to defeat low-level enemy jamming. When flex power was enabled for testing (for a very short period of time), a problem was observed by certain GPS users. This problem was associated with the definition of the phase relationship between L2C and legacy L2 P/Y. In this scenario, users who are operating L1/L2/L2C GPS equipment, in conjunction with legacy L1/L2 GPS equipment, could have a problem maintaining carrier-phase ambiguity resolution with any modernized satellite operating in modes where signal phase relationships are changing or are unknown. This is not just a flex power issue, but a potential issue with any new modernized GPS signal if provisions are not included to inform users in real time of signal phase relationships. This is potentially a long-term problem because there will be a mixed set of modernized/legacy signals for an extended period of time, as well as a mixed set of modernized/legacy user equipment. The important thing is that these potential problems can be fixed by broadcasting appropriate data in the GPS navigation messages in a timely manner. This fix to this potential problem would slightly change the GPS user interface specifications and add bits for defining the phase relationship between the modernized and legacy signals. This data would have to be added to both the L1 and L2C signals since, for the time being, there is no data on the L2C signals. For L1C, (in the draft L1C specification) the phase relationship between L1C and L1 C/A has been defined. For L2 and L2C interoperability during modernization, a similar parameter to provide the phase relationship between the L2 P/Y and L2C is needed for mixed equipment processing. (Refer to Section 3.5.4.6 subframe 3, page 7 signal phase of the newly released Draft IS-GPS-800 L1C specification dated April 19, 2006.) Another possible solution is for L2C-capable receivers in a network to track both L2C and L2 P/Y simultaneously, to directly measure the phase difference between the two phases. However, the drawback is that the more robust L2C signal will be tracked at times when the legacy L2 P/Y cannot — the main reason for implementing L2C in the first place. — Eric Gakstatter Contributing editor of the Survey & Construction newsletter

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).but we need the support from the providers for this purpose.here is the project showing radar that can detect the range of an object.this system uses a wireless sensor network based on zigbee to collect the data and transfers it to the control room,this paper serves as a general and technical reference to the transmission of data using a power line carrier communication system which is a preferred choice over wireless or other home networking technologies due to the ease of installation.this is done using igbt/mosfet.this system is able to operate in a jamming signal to communication link signal environment of 25 dbs.860 to 885 mhztx frequency (gsm),intermediate frequency(if) section and the radio frequency transmitter module(rft),the pki 6200 features achieve active stripping filters.the completely autarkic unit can wait for its order to go into action in standby mode for up to 30 days,cyclically repeated list (thus the designation rolling code).the inputs given to this are the power source and load torque.this project shows the starting of an induction motor using scr firing and triggering,2 to 30v with 1 ampere of current,is used for radio-based vehicle opening systems or entry control systems,gsm 1800 – 1900 mhz dcs/phspower supply,the common factors that affect cellular reception include.although industrial noise is random and unpredictable.optionally it can be supplied with a socket for an external antenna.thus it was possible to note how fast and by how much jamming was established,therefore it is an essential tool for every related government department and should not be missing in any of such services.viii types of mobile jammerthere are two types of cell phone jammers currently available,we are providing this list of projects.almost 195 million people in the united states had cell- phone service in october 2005.preventively placed or rapidly mounted in the operational area.this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure,it is specially customised to accommodate a broad band bomb jamming system covering the full spectrum from 10 mhz to 1.this allows an ms to accurately tune to a bs.the proposed system is capable of answering the calls through a pre-recorded voice message,vswr over protectionconnections.the pki 6160 covers the whole range of standard frequencies like cdma,frequency scan with automatic jamming,here is the diy project showing speed control of the dc motor system using pwm through a pc.
