Abstract
Since its introduction in 1982, MACROMETRYsm technology has consistently delivered the best available accuracy in GPS-based positioning on land. In use on six continents, MACROMETER® Interferometric Surveyors have determined more geodetic positions than any other commercial GPS system. Now Aero Service is extending MACROMETRY technology to marine positioning and real-time navigation.
Aero’s new MACROMETER Marine Navigation System uses the full 10-MHz bandwidths of the GPS Precise Positioning Service signals in both the LI and the L2 bands. Therefore it can outperform any C/A-code, L1-only instrument. The already substantial dual-band advantage will increase greatly within the next few years as we enter the up side of the solar cycle.
Like the dual-band MACROMETER IITM System, Aero’s Marine Navigation System operates independently of the GPS P- and Y-codes. Code secrecy and access limitations will have no effect on the performance of Aero’s systems. Moreover, since Aero has an independent satellite tracking and orbit determination capability, system performance will be unaffected by degradation of the accuracy of the broadcast orbital data.
Aero’s Marine Navigation System will be capable of operating in both standalone and real-time differential modes. Differential operation will be needed if immunity to satellite clock and oscillator dither is required. In differential mode, Aero’s system will operate as far as 1000 kilometers away from a reference station without degradation of accuracy above the 1-meter level. Because of this ability, it is not necessary for the user always to establish a nearby shore station. This is clearly an economic advantage. Improved reliability and operational flexibility are also gained if marine operations are not dependent on nearby shore stations.
