Abstract: This technical memorandum provides the results of a compatibility assessment between terrestrial GPS L1 coarse/acquisition (C/A) code receivers operating in the 1559-1610 MHz RNSS band and terrestrial operations in the 1526-1536 MHz, 1627.5 1637.5 MHz, and 1646.5-1656.5 MHz bands. The Interdepartment Radio Advisory Committee (IRAC) Technical Focus Group (TFG) assessed compatibility between different categories of GPS L1 C/A code receivers and the proposed terrestrial deployment by examining the degradation in carrier-to-noise density ratio (C/N0), loss-of-lock, position error, and increase in acquisition/reacquisition time for GPS receivers.
