Technical Specifications - VBOX 3i Dual Antenna (v5)
This page covers the technical specifications for VBOX 3i Dual Antenna v5 units (VB3iSL-V5, VB3iD-V5 and VB3iD-V5a), for areas such as GPS, Slip, Pitch and Roll accuracies, IMU attitude accuracies, inputs, environmental and physical attributes.
Definitions
| * | Specifications will vary depending on the number of satellites used, obstructions, satellite geometry (PDOP), multipath effects, and atmospheric conditions. For maximum system accuracy, always follow best practices for GNSS data collection. |
| ** | Not using DGPS and crossing the start/finish line at 100 km/h. |
| *** | Approximately 29 MB per hour used when logging GPS data at 100 Hz; Approx. 182 MB per hour total logging capacity. |
