For example, the preoperational broadcast of L2C signals from the IIR-M satellites did not include any NAV orCNAV data as required by IS-GPS-200. Pre-operational use of any new signal or group ofsignals is at the users own risk.6.4Operational Protocols.6.4.1 Lower PRN Numbers Versus Upper PRN Numbers.Many existing user receivers are only compatible with prior versions of this IS where the PRNnumbers and corresponding PRN code sequences were limited to the lower range of 1 - 32. Tomaintain backwards compatibility with these receivers (and promote backwards utility), the CSwill endeavor to operate as robust a constellation as practical using just the lower range of PRNnumbers. The upper range of PRN numbers (33 - 63) is intended as an enhancement for63IS-GPS-200H24 Sep 2013modernized receivers which are compatible with both the lower PRN numbers and the upperPRN numbers.
