| Abstract: | A third civil frequency at 1176.45 MHz will be added to the Global Positioning System (GPS). This new frequency will bring
a number of benefits. The aviation user will be one of the prime beneficiaries because the new frequency is in a protected
aviation band. Thus, the system will be more robust against interference and jamming.
The carrier-phase differential user will also be a prime beneficiary as long as his application has a reasonably short baseline.
It is this high accuracy use that is explored in some depth. The process of forming linear combinations of both the code and
carrier-phase measurements is studied, and the benefits and problems are explained. ? 2000 John Wiley & Sons, Inc. |
