About GPS
GPS (Global Positioning System) is a system of navigational satellites. Commercially available GPS receivers can calculate and report their geographical position and other navigational data (called a fix) based on signals transmitted by these satellites.
NOTE: The GPS feature is not supported in the 64-bit version of Omnipeek.
Omnipeek can display data provided by a separately purchased GPS receiver. For each packet, optional columns in the Packets view can show the GPS Time, Latitude, Longitude, Altitude, and Speed currently reported by the connected GPS receiver. This is especially useful if you needed to identify where you were when you received a set of packets.
NOTE: The GPS receiver requires clear access to the GPS satellites in order to display data in Omnipeek.
For example, if you worked on a large military base, you might need to identify the reach of your wireless network. Using Omnipeek and the GPS receiver, you could drive around the base capturing wireless packets with the GPS device providing you with coordinates. The resulting captures would provide a set of packets with their signal strengths from your network and a set of coordinates for your location.
Omnipeek uses a separate utility, the LiveAction GPS Daemon, as the interface between itself and your GPS receiver. The daemon supports GPS receivers that follow the NMEA (National Marine Equipment Association) 0183 standard which provides data in recognized GPS sentences (comma-separated ASCII data strings) in the GPRMC and GPGGA formats.
Refer to the manufacturer’s instructions for your particular GPS receiver for information on how to use features of your GPS receiver.
