This invention discloses a method for enhancing a Global Navigation Satellite System, such as Global Positioning System, location calculation by supplying carrier phase corrections within a GNSS receiver used with a multiple element Controlled Reception Pattern Antenna receiver. Because there is no material removed next to the seals, the gap between the orbiting scroll and crankcase remains intact in the sealing area and the seals continue to operate properly preventing the refrigerant leakage through the gap. A validation is received from the host system for the discount instrument and a cost of the transaction is reduced in accordance with a discount arrangement associated with the discount instrument. For optimal viewing, illumination level of the front and back lighting device are adjustable, and a variety of interchangeable optical lens can be further disposed to modify their light beam morphology and characteristics. The noble metal substantially prevents oxidation of the solder performs surfaces while the preform is heated to reach reflow temperature.
