When writing out RINEX3 content in RINEX2 format, the input loss of lock indicator (LLI) should be added decimal 4 before outputting it, in case the observation type is a precise code. For example, this is the case when mapping R3 GL1W to R2 L1; in contrast, R3 GL1C to R2 L1 should leave LLI unchanged.

Background (from RINEX 3 specs): "AS-infected observations have been flagged in RINEX Version 2 using bit number 2 of the Loss of Lock Indicators (i.e. their current values are increased by [decimal] 4). In Version 3 there are special attributes for the observation type to more precisely characterize the observable (codeless, semi-codeless, Z-tracking or similar techniques when AS on, L2C, P-code when AS off, Y-code tracking), making the AS flag obsolete."

Thank you for bringing this to our attention. We have verified that what you have stated is correct, and will be updating the code once we have mapped the RINEX Obs - LLI relations between RINEX v2 and v3.
