NMEA Parameters

General Parameter Notes

* All endpoint values are included in valid data range, if applicable.
** A positive value compensates for that amount of delay in the signal path.
‡ Only applies to PPS_1, and does not affect the u-blox configuration
◊ Parameters are SET at runtime, thus the use of GSGET or GSSET from/to volatile memory is invalid and will return GSRSP error code, ‘UNSUPPORTED_MEMORY_CLASS‘ as defined in table 8 of the NMEA Sentence Integration Guide.

One Time Programmable (OTP) Parameters

*** Some parameters can only be configured once. If a user attempts to configure an OTP more than once, the application will return GSRSP error code, ‘CANNOT_CHANGE_OTP_PARAMETER‘ as defined in table 8 of the NMEA Sentence Integration Guide.
