NaviSpotter is vessel tracking software for shipping companies. It facilitates logistics operations in many areas including Chartering, Crewing, Purchasing. Apart of similar services NaviSpotter does not use AIS signal which is limited by VHF range, our services coverage is world wide and limited by coverage of your internet provider only. Nowadays 90% of Earth and 100% of main shipping routes covered by major satellite internet service providers.

The main difference is that you track your vessel over it's real planned route, which is imported from vessel's ECDIS

GPS data is fetched by our client apllication and then encoded data is being sent to Navispotter server over secure HTTPS connection for further processing & displaying to the end user. The data being collected could be accessed by the vessel's owner / operator only or by users who were expressively granted such access by the vessel's owner / operator. Navispotter does not share the data to third parties including anonymised statistical data.

One of advantages of our service is the abscence of necesity to install any additional hardware / equipment. All that you need is already existing on board. The only thing remained to do is to connect a bridge computer with internet connection to GPS or GPS splitter with serial cable.

N.B. : Use shielded cable in order to prevent an interference from radar's waveducts and/or other emitting equipment which may cause NMEA signal corruption.

    Check which port number is assigned to your GPS connection, for that open the Device Manager find "Ports" as shown on picture:

    Normally it has to be "COM1".

    Start NaviSpotter.exe...

    Select "GPS" tab

    Select COM port by dropdown list [1]

    Choose baud rate by control [2] Standard for NMEA 0183 is 4800

    1. Port: COM1 (Set to port figured out in the previous block)
    2. Baud Rate: 4800
    For R4 Navigation System please check real baudrate for a connected output port. Setting could be found in GPS "I/O Config" menu. Please refer to picture below.

    For R4 Navigation System in order to estimate and setup NMEA output press "MODE" button, then select "I/O Config" button. The goto Port Output Configuration and make sure that following NMEA sentence are enabled:

    1. $GPGGA
    2. $GPGLL
    3. $GPGSA
    4. $GPGSV
    5. $GPRMC
    6. $GPZDA

    Click button [3] to apply settings and open COM port.

    In case all setting were made right COM [3] LED will start blinking and correct GPS data will be displayed on the program's screen.

    Correct settings will be automatically saved.
    Client Side

    Select "Account" tab

    Copy the request code and send to your service administrator

    Server Side

    Administrator having the request code will generate an activation code by clicking activation pictogram of previously registered vessel as shown on the picture above.

    Paste the obtained request code into the prompt window and click "OK"

    Server will reply with activation code which in a turn has to be sent to the vessel to finish the activation procedure

    Client Side

    Software is activated and fully functional


    The info window could be called by clicking a vessel's symbol on the map. First screen displays general info including:

    1. Present Speed
    2. Course over ground
    3. Port of origin
    4. Port of destination
    5. Distance to destination
    6. Estimated time of arrival
    7. Latest update received time

    Second screen (scroll down to view) displays vessel's speed over last 24 hours. To se the speed value hover mouse pointer over the graph.

    Third screen displays short Master's notes if any.

    N.B. In case there are no notes available third screen will not appear.

    Navispotter provides data for over 3600 sea ports world wide. The data presentation provided in convenient form covering most points of interest.

    Sea ports information

    Right click on a vessel activates range measuring circle. To measure a distance to an object drag a white handle on the circle. In case last received speed is above the zero in addition to a measured distance the ETA will be shown. To close the measuring tool right click it.

    Speed vector is showing the distance the vessel will make with the present speed. Vector length could be set in range between 1 & 96 hours. Information could be useful in case of propulsion failures in order to estimate vessel's estimated position or for rough estimations of ETA to a certain points. Vector is being built from the last received position

    In order to use the distance/bearing ruler click ruler pictogram [1], place measuring pins [2] between objects to measure, read measured data in the field [3]. To deactivate the ruler click it again.

    By pressing the secret combination of keys covert security alert will be risen and appropriate message will be dispatched. The alert feature works even if the Navispotter window is not in focused or resides in system's tray.

    Important! The security alert feature does NOT substitute conventional SSAS security buttons and is additional mean to alert the Company only.

    The SpeedSense™ is innovating speed control feature based on machine learning. Self learning algorithm uses history data and location of a vessel to estimate whether slowing down is planned or not and alerts in case unexpected slowing down is occurred. No any inputs from user are necessary.

    Nowadays most on-board mail systems still work by store and forward model, therefore delivery of messages depends on frequency of e-mail exchanges performed by a Master. Navispotter messaging service works in different way, ship's client checks for new messages every 60 seconds and pop them up immediately with very low traffic consumed.

    Visual presentation of Sulfur Emission Control Areas allows to monitor voyages & plan bunkering using together charted SECAs, route presentation & immediate vessel's position.

    Known Issues

    Rambling mouse pointer movement behavior is caused by the GPS being mis-identified as a modem or serial trackball or serial mouse. The mis-identification is done in the module serenum.sys, a plug-and-play device enumerator that is invoked by default by most serial drivers, including the Windows default serial drivers. Among other things, this module detects incoming data to try to identify various legacy serial devices using identification techniques that were devised in 1995 for pre-existing modems and pointer devices.

    There are several possible solvations

    1. Use Navispotter MouseTrap tool

    2. Download

    3. Manually edit registry

    4. [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\sermouse] "Start"=dword:00000004

    In case of recrudescence which may happen after of installation of any HID device and/or drivers of such simply repeat a chosen procedure.
    Upon migration from v.2 to v.3 depending on the Navispotter build installed on your computer it may be required to deinstall old version prior installing the update. Use windows Add or Remove programs for that. In case update has been downloaded already it could be located in:

    1. Windows 7 and newer

    2. C:\Users\[YOUR USERNAME]\AppData\Roaming\NaviSpotter

    3. Windows XP

    4. C:\Documents and Settings\[YOUR USERNAME]\Application Data\Roaming\NaviSpotter

    5. All Versions shortcut

    6. %appdata%\NaviSpotter
      Simply copy the shortcut above into the Explorer's address bar.

    Run setup.exe
    COM Port resets are being initiated by Navispotter application in order to withstand the framing errors. Framing errors normally occur when:

    1. baud rate mismatches
    2. Solution: Set Navispotter COM Port settings to the settings of GPS Unit
    3. the serial line is very long
    4. Solution: Try to set baud to lower rates [ only if no other navigation equipment is connected to the same GPS unit!!! ]
    5. there is a lot of electrical noise on the serial cable
    6. Solution:
      1. Ensure that there is proper cable connection on both sides of cable. E.g. cable plug is duly bolted into the COM Port on computer side, and wire soldered or properly jointed with a wire clip on GPS side.
      2. Use shielded wire
    Framing errors can also occur if there is no serial ground connection between the two connected serial devices, or if the connection is intermittent or has a high impedance, e.g. because one or both ends are not well connected. This can cause noise on the serial line, resulting in framing errors.
    Make sure your serial cables are not excessively long, especially in electrically noisy environments which a wheelhouse actually is. In general a serial cable should not be longer than 15 mtrs for communication at 9600bps. Faster speeds require shorter cables, slower speeds allow longer cables. In general, the shorter the cable and the slower the serial speed the more reliable the connection will be.
