Last Updated: June 2020 ZUPT - or Zero Update Position and Timing, is used to mitigate gyroscope bias drift and in turn mitigate heading drift in a [GPS-Denied environment](https://resources.inertiallabs.com/resources/tunnel-guide-feature-for-ins-improves-performance-during-gnss-outage). It should be enabled when the user wants to reduce its accumulated orientation and position errors once a carrier object stops. If a completely motionless state is not achievable, then the user should disable the ZUPT option.

Last Updated: June 2020 When using the [Inertial Navigation System ](https://inertiallabs.com/products/ins/)(INS), position error accumulation is always a concern. One way a user can limit this error is by enabling the [“Tunnel Guide”](https://resources.inertiallabs.com/resources/tunnel-guide-feature-for-ins-improves-performance-during-gnss-outage) feature (**only available for fixed-axle land vehicle**).  When enabled, it allows the INS to reduce its accumulated errors during extended GNSS outages. Use this feature when external aiding data is unavailable. To do so, go to the “Correction options window of the “Options” tab and enable “Tunnel guide” as shown below.

Last Updated: March, 2020   **Customer:** I have found one issue that I am currently confused with. The timestamp recorded from COM1 of the [INS](https://inertiallabs.com/products/ins/) is consistently 17-20 seconds fast. If I start recording at 00 seconds, the first timestamp is equal to 17+ seconds, however the location data that comes from the GPS receiver is correct for 00 seconds and not 17+ seconds. Any insights into this issue?
