Unfortunately, there is nothing that can correct for wheel slippage in the odometer feed as it relates to dead reckoning. However, TACNAV does compare its calculated distance against the distance traveled according to GPS. If there is a discrepancy between the two, TACNAV will temporarily adjust the odometer calibration factor to compensate for the difference.
Power lines have an insignificant effect on the TACNAV compass, unless you are next to a large substation with transformers. The lines themselves are typically too high to affect the compass. However, they may interfere with GPS reception.
No, TACNAV is a magnetic-based system and does not drift.
Yes. TACNAV systems have been used in combat and peacekeeping operations since the early 1990s.
Compass calibration will be required whenever the TACNAV-equipped vehicle travels into another magnetic latitude. If, for example, the vehicle is airshipped to another field of operation, calibration would be required. TACNAV features a display that will indicate when the calibration is questionable.
TACNAV II can function either as a single-box navigation module or be expanded into a multifunction TACNAV system, making it ideal for complete integration with virtually any platform.

KVH offers three TACNAV systems that offer a range of functionality and compass heading accuracy. Compass heading accuracy is also dependent on the quality of the compass calibration. The typical accuracy for each system follows:

TACNAV Light: 2-3 degrees compass heading accuracy

TACNAV TLS: 2-3 degrees compass heading accuracy

TACNAV TLS with the T-FOG Upgrade: 0.5 degrees compass heading accuracy

TACNAV II: 0.5 degrees fiber optic gyro heading accuracy
