Introduction

Since I built my new website I've seen a lot of 404s for my old GATSO Hunter page. I've also had emails asking if the software is still available.

Because of this unexpected interest I have recreated the GATSO Hunter content as an article.

Requirements

1. Microsoft Windows. XP SP2 is known to work, Windows 2000 will probably work, Windows 98 might work. The executable is very simple so the chances are good.
2. MSCOMM32.OCX in your system32 folder and registered.
3. An NMEA GPS receiver connected to a working COM port. (Or virtualised with a USB to COM driver).

Installation

1. Extract the ZIP file to a folder of your choice, keeping all the files together.
2. Edit GATSO Hunter.ini and change the COMPORT setting to match your system configuration.
3. Run GATSO Hunter.exe.

Configuration

• CLOSEZONE
  Radius in kilometres, from the current position, that you want to monitor cameras. After moving (CLOSEZONE - 1) kilometres from your current position the program recalculates the close cameras. For that reason don't set it to 1 or below!
• WARNZONE
  You will be warned about any cameras that are closer than this value (in kilometres).
• HEADINGTOLERANCE
  Number of degrees to the right and to the left of your current heading to look for cameras.
• COMPORT
  The com port your GPS is on.
• COMSETTINGS
  Baud rate etc.
• CAMERAFILE
  Name of the CSV file containing the camera positions.
• SPEEDUNIT
  mph or km/h or anything you want really! All this really does is tweak the interface. The speeds in the CSV are just numbers so this helps the program give them meaning. It does not stop the program using km/h for all it's calculations. The WARNZONE and CLOSEZONE units are always km's whatever you set this to.
• WARNATLOWSPEED
True or False (case sensitive). Set this to False if you do not want an audio announcement about approaching speed cameras when your speed is below 5km/h.
• WARNGPSNOTLOCKED
False, Once or Always - Determines how often you get warned about the GPS not having a positional fix. Once will warn you one time, until a fix is re-acquired. If that fix is then lost it will warn you, once, again.
• WARNGPSNOTLOCKEDINTERVAL
  If you are using Always warn (see above) then this lets you set the interval (in seconds) between the warnings.
• WINAMPMUTE
False, Pause, Absolute or Relative. Determine how GATSO Hunter will try and deal with Winamp. False and Pause are obvious. Absolute will turn the volume to around 1/3 of the total scale and after the warning has been spoken will put the volume up to 100%. (Regardless of what you had the volume on before). Relative will move the volume down by a number of units and then back up by a number of units. (See below).
• WINAMPRELATIVE
  0-64. Determine how many units (on a scale of 0 to 64) to shift the Winamp volume by when WINAMPMUTE is set to Relative. (See above).

Camera data file

The speed camera database format is the same as the one used at PocketGPS.

When you download an updated ZIP from PocketGPS you need to look for a file in this format:

Longitude,Latitude,Name
-0.76298,51.98999,"GATSO:5244@30"
-0.24594,52.58497,"GATSO:0890@30"
-2.77217,55.74874,"GATSO:3110@60"
-0.32181,51.33441,"GATSO:4834@40"
-0.39686,52.57074,"GATSO:5951@70"
-0.40146,52.57444......

It should be with the CSV files.

Adding speed cameras

You can only add cameras when you have a fix.

Hit the "Add Camera" button and then press the camera type buttons and the speed buttons to build the information that you will be adding.

You do not have to select a speed to add a camera.

The position info will update while you're on the "Add a speed camera" form. So you can prepare the info you want to add and then hit the "Save" button as you drive past the camera.

The camera info is automatically added to your camera database CSV.

GATSO Hunter also writes information about the camera to a file called GATSOHunter_submission.txt in the same folder as GATSO Hunter.exe. This file can be emailed to PocketGPS and other camera position repositories.

Apologies in advance for the poor quality VB6 source code. It does the job, but it sure is ugly!
