Channel Configurations Explained

Each model contains at least 5 sets of channel configurations. These first 5 sets align to these categories:

Configuration	Category	Notes
1	Standard Configuration	Has one signal from each frequency, if the signal is verified.
2	Minimum Number of Channels	Has dual frequency for all constellations. The benefit is less data and less power consumption than High End Positioning.
3	High End Positioning	Has extra frequencies and channels for better positioning performance. Has all verified and trusted signals (may include multiple signals per frequency such as GPS L2C and L2P).
4	Maximum Number of Channels	Has all verified and trusted signals + BeiDou B31 BeiDou B3 is a special case. It does not have a released ICD, but NovAtel has tracked and verified the signal If there is a problem with using B3, NovAtel recommends changing to configuration #3.. Typically used for reference stations or where power and idle time are not a concern.
5	Experimental Signals	Has all signals regardless of verification status. The extra signals might not be used in positioning by default (GPS L1C, GLONASS L3, QZSS L1C, NavIC L5).

OEM7 Model Specific Notes

As of firmware version 7.04:

• Dual antenna models starting with FDD only have one possible channel configuration. The CHANCONFIGLIST log will just show duplicate configurations, and it doesn't matter which one you choose.

• FF models also have NavIC L5 in configuration #4.

• The default channel configuration is #3 (High end Positioning) when CORRECT Positioning char[4] is P, R, or B. Otherwise, default is #1.
