Detailed Description

The GPS beacon structure.

This defines the structure of the GPS beacon.

The GPS beacon consists of sixteen members: identifying information for the beacon (type and deci), position data (latitude, longitude, speed, angle, and altitude), GPS qualtiy data (satellites, fix, and fixquality), and date/time data (year, month, day, hour, minute, second, and millisecond).A diagram of the struct is included below.
