GPS just got better, easier to sell
Article Abstract:
Global positioning system (GPS) users can expect the accuracy of their instruments to have increased by ten-fold as of May 2, 2000. This is when the US military turned off its 'selective ability' GPS signal-distorting degradation satellite clock. Marine electronics retailers have been broadcasting this development to buyers, resulting in a dramatic increase in GPS sales. Even manufacturers of differential beacon receivers, which radically improve the accuracies of fixed-mount GPS, expect sales to improve as their products will continue to provide GPS users with a number of other benefits.

Rollover woes plague GPS makers
Article Abstract:
Global Positioning Systems (GPS) equipment manufacturers encountered several unexpected problems as the 1024 week rollover occurred on Aug 22, 1999. Some GPS receivers had trouble performing their functions properly unless the rollover situation had been programmed into the unit's software. Garmin, one of the most respected makers of GPS equipment, was one of those that were caught off guard as its sets stumbled on satellite lock-in after the rollover. It quickly posted easy dealer and user reset instructions to get equipment back on the air at no cost to the customers.

Still in testing stages, WAAS has a bright future
Article Abstract:
The Federal Aviation Administration's Wide Area Augmentation System (WAAS) will likely be widely demanded in the near future. WAAS enables standalone, fixed or portable global positioning systems with no external differential beacon black-box receivers to decode one additional correction satellite signal. These signals are transmitted on the L1 frequency band for civilian receivers. WAAS is the basis of a new Raytheon Marine Co system that has proven to deliver extreme accuracy in sea trials in Newport Harbor, CA.
