The PicoDopp DF is an economical but very sophisticated Doppler DF "kit" with a GPS input, RS232 and IrDA ( infrared ) outputs. "Local" display boards are optional, see OPTIONS page for details.

Free display programs ( see below ) are provided for IBM PCs and for ( cordless/handheld ) PalmOS PDA displays. A very sophisticated "moving map" display program is also available from GPSS Sunninghill, in the UK. ( free demo version, US$ ? for full features )

PicoDopp Includes six assembled / tested PC boards : MAIN board, ANTENNA board and four TERMINATION boards. ( one for each of four antennas ) Completion work is required by the user, to finish the DF. Guidelines for the completion work are provided. ( see link below picture )

The user must provide an FM reciever, enclosures, an antenna platform, a display computer, ( IBM or PDA ) and interconnecting cables. The SunningHill display program further requires a GPS reciever with NMEA 4800 baud output.

The WinDopp IBM PC / Windows display program is a Windows display program for the PicoDopp DF. It has a simulation mode that allows it to be used without a DF input... you can download it and run it now. If a GPS reciever is provided, the WinDopp program uses the GPS heading to stabilize the azimuth display, which fully enables the signal integration features of the program.

WinDopp uses an RS232 COM port 1 - 8 ( or USB port with user-provided adapter ) and selectable baud rates, 1200 to 9600. Standard Agrello DF message allows use with other DF units. User defined color scheme and COM settings are saved on exit, selectable GPS or manual heading inputs. Includes 3 quasi-DSP features to enhance the display and assist identification of signal direction.

The GoogleHunt display program is a Windows display program for the PicoDopp DF that uses a GoogleEarth screen to display mutiple PicoDopp DF bearing lines, previously recorded during a vehicle hunt.

GoogleHunt uses an RS232 COM port 1 - 8, or USB port with user-provided adapter. Standard Agrello DF message allows use with other DF units. User defined color scheme and COM settings are saved on exit, selectable GPS or manual heading inputs and manual or Agrello DF bearing inputs.

The DoppSite DF remote display program allows remote, realtime viewing of a DoppSite base station DF, using a GoogleEarth display and an internet link to the DF site. DoppSite can drive multiple displays simultaneously, with updates as fast as once per second. This makes Doppsite an excellent tool for creating DF networks that allow a signal to be localized to 1 or 2 square miles, in a matter of seconds. Any PC with internet access and GoogleEarth installed can display one or more DoppSite DF stations,and their DF bearing lines, instantly.

The DoppSite program is installed on a PC running at the DF site. It accepts an RS232 input from a PicoDopp DF, and generates a NETWORK output ( from an HTTP server ) that "serves" KML ( plotting ) files to one or more GoogleEarth displays, through the internet. GoogleEarth can be given IP adddress and port information, ( in a NETWORK LINK ) to find the DoppSite program via the internet, and fetch the DF datafor display.
