A:
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.
A:
Yes. The T-FOG Upgrade is designed for easy integration with the widely fielded TACNAV TLS system. Once integrated with TACNAV TLS, the fiber optic gyro-based T-FOG Upgrade provides a variety of accuracy and performance improvements, including:

- improves target location from 300+ meters to 75 meters at 5 km range
- improves DR accuracy from 3% to 1% of distance traveled
- improves pointing accuracy from 35 mils to 10 mils
A:
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.
A:
No, TACNAV is a magnetic-based system and does not drift.
A:

Yes. As an upgrade to the TACNAV TLS system, the T-Fog Upgrade interfaces with a vehicle's existing systems, including the odometer, turret angle encoder, laser rangefinder, and GPS.

A:
Yes. TACNAV systems have been used in combat and peacekeeping operations since the early 1990s.
A:
The T-FOG upgrade improves operational effectiveness by facilitating accurate mobile integration of direct fire weapons and fire zone coordination.
A:
The T-FOG Upgrade improves DR accuracy from 3% to 1% of distance traveled.
A:
The T-FOG Upgrade improves pointing accuracy from 35 mils to 10 mils.
