SiRFstartIII is not Glonass IRC, http://www.sirf.com/Downloads/Collateral/GSC3(f)_6.20.05.pdf Besides GPS+GLO(+GAL) are going to 72 channels... "GeNiuSS$(C"b(B consists of 72 channels of GPS (L1-CA, L1-P, L2-CA, L2-P, L2C), GLONASS (L1-CA, L1-P, L2-CA, L2-P) and all Galileo signals (L1, E5, E6). The implemented Galileo code generators are very versatile such that we believe they will be able to cover a wide range of codes and modifications to Galileo signal structure when they are finalized. JNS is currently offering the GeNiuSS$(C"b(B chip for certain research purposes until Galileo is deployed. Please contact us for further information. Products based on this chip will be released in the fourth quarter of 2005. " -- Bj.ANvrn
