GPLocator FAQs

• Supported web based systems

  There are a two supported formats, both of which are listed here. Minimally, any format must contain a vehicle ID, time of position and position in practically any coordinate system (although WGS84 geographic coordinates are most common). Dynamic Survey Solution will support additional protocols at no charge.

  UDP PACKETS

  This is a GPGGA message that GPLocator would receive over an ethernet connection in the form of UDP packets. The origin IP address would uniquely identify the vehicle.

  (FMS) WEB REQUESTS

  GPLocator presently supports Fleet Management Solutions (FMS), a company that provides its client with vehicle tracking packages consisting of a GPS receiver and a phone (cell or satellitte). Their system relays the position of each vehicle to their website where the data is available to anyone with the correct user name and password. GPLocator can be configured to make periodic request for vehicle position data from their website.

  The Raveon data has the sender's ID as the second comma delimited string.

• Supported flat files

  GPLocator supports the following data files. These are produced by 'black box' instruments that are placed on vehicles and record positions, but don't work with a radio link. When a vehicle returns to base, the contents are downloaded to a PC as an ASCII file. GPLocator can quickly create log files from these file which in turn can be played back or analyzed.
