program on a PC, a Radar set – typically there is other information needed: position,
course over ground, time & date, the GPS satellites’ status and so on. Update rates
required are usually slow – 1 Hz or less.
As mentioned previously, the G2 is configured at the factory for easy use in typical marine
situations, such as illustrated in Figure
