    How to fix GPS data using SirF IV

    Hi all, In our Vehicle Tracking System device, once the device starts up, the device didn't able to capture its current position, i.e actually where it is standing and showing some other location. NB: The device connected in the ignition of the vehicle and the device's power cuts off after 30...

    GPS/GPRS/GSM Combo Module

    Hello all, Can anyone suggest right product of GPS/GPRS/GSM combo module?? Similar to SIMCOM's SIM 908. Also any module is available to switch over one network to another network in case of network failure?? This would be highly useful for GPS/GPRS based Vehicle Tracking Systems?? Pl suggest.

    How to reduce Off-time delay in switch over condition using P-channel MOSFET

    Thanks Barry. Main DC supply passes thru the circuit thru 10K. Vbat is the battery supply to which the circuit to be switch over when the main DC supply gets cut-off. The Load is connected to Drain.

    How to reduce Off-time delay in switch over condition using P-channel MOSFET

    Hi, We are using a P-channel MOSFET (FDC642P) as a switch from main DC supply to battery supply. There is a time delay about 1sec, in which he in-built S-RAM looses its content. Any suggestion to reduce the time delay?? Your help is highly appreciated. Circuit attached.

    How to convert 4V20mA to 4v 500ma??

    Hello all, We have an circuit which produces 4V/20mA as output thru PIC 18F46K22. This O/p to be given as I/p to a Analog Fuel Gauge meter which needs 4V/500mA. Help us to step up the same.

    How to control Fuel Sloshing

    Hi all, Here is my issue. We have a GPS vehicle tracker system, with which vehicle's fuel sensors connected to check the fuel level. When the vehicle in running condition, FUEL SLOSHING causes wrong reading. Any solution is appreciated to arrest the fuel sloshing. We are using both resistive as...
