Memory for GPS-based golf distancing system
DCFirst Claim
1. A GPS-based golf distancing system, comprising:
- a GPS receiver for receiving GPS signals and for determining a current location of the system on a golf course;
a digital memory for storing a digital map representation of the golf course, the digital map representation defining at least one location;
a data processor for correlating the current location to the one location to determine distance between the current location and the one location; and
means for updating the digital memory with a new digital map representation, to compensate for physical movement of the one location, the physical movement being detectable through GPS location accuracy, in the determination of distance.

Abstract
A portable distance tracking system for use by a player on a playing field wherein the playing field includes at least a first landmark and wherein the system comprises at least one mobile interface unit. The mobile interface unit includes a memory element, position interface electronics, a data processor, and a player interface. The memory element stores digitized map representations of playing fields. The position interface electronics receive position indicative signals from and external source, wherein the position indicative signals are representative of a geographical location of the mobile interface unit. The data processor couples to the memory element and to the position interface electronics and correlates the geographical location to a field location of said mobile interface unit on said playing field. The processor also determines the distance from the mobile interface unit to the first landmark. The player interface is coupled to the data process and communicates the distance between the mobile interface unit and the first landmark to the player. According to a preferred embodiment, the playing field is a golf course and the first landmark is a flag location at a select hole on the golf course.
