RTKINTEGERCRITERIA

Report inaccurate fixed-integer RTK positions with float solution type

Platform:

OEM719, OEM729, OEM7500, OEM7600, OEM7700, OEM7720, PwrPak7, CPT7, CPT7700, SMART7

This command forces a fixed-integer RTK position to be reported as float if the estimated solution standard deviation exceeds a threshold.

Normally, a fixed-integer solution is very accurate. However, in some rarely-occurring situations, even a fixed-integer solution can become inaccurate; for example, if the DOP is high due to satellites not being visible. In such cases, the accuracy of the RTK solution might be worse than what is customarily expected from a fixed-integer solution. The RTKINTEGERCRITERIA command changes the solution type of these high standard deviation integer solutions to their float equivalent. NARROW_INT, for instance, becomes NARROW_FLOAT. Depending on the GGAQUALITY command setting, this will also impact the NMEA GGA quality flag.
